Performance characteristics and working principle of Chemical Ground Electrode:

1. Chemical ground electrode
2. Existing soil
3. Special filler
4. Ions diffuse around
5. Expand the conductive range of the soil

installation earth electrode is a new type of grounding system suitable for all kinds of places with high grounding requirements and difficult grounding engineering.

The chemial grounding electrode system  consists of advanced alloy compounds, with a copper tube on the outside to ensure maximum conductivity and long service life. The filling material inside the conductor contains special ionic compounds, which can absorb moisture in the air adequately. Active ions can be effectively released into the soil through the deliquescence, and interact with the moisture in the soil and air to further promote the external slow release and drag reduction of conductors, and to maintain the long-term stability of the resistance value. Compounds in conductors are gradually combined in colloidal transparency over time.

By utilizing the conductivity of the colloidal compound, the entire system can be ion-exchanged for a long time, thus forming an ideal electrolytic ion grounding system. After the slow-release filler in the conductor is embedded, the grounding resistance will gradually decrease, reaching a stable value within six months to one year, and the embedded slow-release process can last for several years. The main connecting parts of the ion grounding electrode are hot-melt welded, which has overcome other connection methods and easy connection loosening.

The connecting wire is a copper clad steel copperweld stranded wire with a section of 95 mm2 and a length of 3 m and is crimped to the grounding terminal/copper lug to facilitate connection with the copper clad steel grounding.

Chemical Ground Rod Specification and models

The grounding electrode of BEISUDA COMPANY electrolytic ion fully meets the requirements of grounding protection equipment such as UL, NEC, ANS, lEC, BC and other international standards.

Chemical Ground Electrode application range

Lightning protection and grounding works for petrochemicals, oil storage, power plants, substations, communication base stations, airports and network computer rooms, etc.

The copper-clad strand wire is shaped like a cable ccs, which is made of a plurality of copper-clad single wires. Because of its multi-stranded properties, the electrical conductivity and tensile strength are relatively good, and the product can be customized to enhance the elongation rate by multiple heat treatment in the production process, which has increased the strength and toughness of the steel compared with the pure copper strand. Moreover, the good electrical conductivity and corrosion resistance of the copper material are maintained due to the principle of the skin effect. Therefore, it is very popular in many fields of lightning protection and grounding, especially in power plants, substations, high-speed rail, subways, electrified railways, large-scale chemical plants, mechanical plants, communication base stations, transportation, computer rooms, highways and military bases.

Copper Clad Steel Stranded Wire Characteristics

3.Long life

The copper plating of single-stranded copper-clad round steel (copperweld steel) of multi-stranded copper-clad strand is thick, the excellent production process makes copper layer tightly combined and bent 180-360 degrees without cracking and its life is long and can be more than 30 years.

4.Low cost

The characteristics of high conductivity and corrosion resistance have greatly reduced the number of grounding conductors used in grounding projects, which can significantly save costs and achieve outstanding economic benefits.

5.Convenient construction and transportation

The single length of the copper-clad copperweld strand can be up to 100 meters, because the 100-meter package or the hundred-meter cable can be transported more easily. The welding between the grounding grids during the construction is recommended to use the exothermic welding series products produced by our company. There are different shapes of molds for exothermic welding, so that different permanent joints can be randomly welded. The construction operation is simple and easy to learn, and the various conductors of the grounding grid are welded together to become a true maintenance-free device.

Specification and modles:

Note: tinned copper-clad strands and PVC insulated copper-clad strands can be customized according to customer requirements.

Origin of new material development

0.8mm series copper-clad round wire is a new type of material developed by our Company to replace pure copper. Because it has the advantages of high strength, low price, high corrosion resistance and high conductivity of copper, and meanwhile its comprehensive performance is high and its cost is more economical than pure copper grounding device, it has been widely used in UHV lines, petrochemical industry, nuclear power and high-speed railway, especially in key projects in recent years.

coated ground wire:

The material in which the surface of a steel core is uniformly coated with copper includes copper-clad steel bars (for vertical grounding electrode only), copper-clad steel tape, and copper-clad steel wires (including round wires and stranded wires). According to the production process, it can be divided into continuous casting copper-clad steel and electroplating copper-clad steel.

Development of copper clad steel grounding device

With the increasing voltage level of power lines and the increasing capacity of the system, higher requirements are put forward for the safety and reliability of grounding devices.

The traditional method in foreign countries is to use pure copper as the grounding material, but pure copper is expensive and it is a strategic resource, which is not suitable for being massively used as grounding devices in China. From 1910 to 1955, National Bureau of Standards (NBS) conducted corrosion resistance studies of grounding bodies. 36,500 samples collected at 128 test sites throughout the United States represented 333 metal materials consisting of iron, non-ferrous metals and protective coatings, respectively. The test results show that only steel bars and stainless steel bars with copper plating thickness over 0.5mm can be accepted.

In addition, continue the statistical data of 8 to 30 years and take the test results of 43 copper samples in different soils, 41 of which were calculated, to get the 0.17mm average pitting depth of 30 years. Therefore, some international standards have determined the thickness of copper coating of copper-clad steel material to be at least 0.25 mm. Considering the hard friction during construction, it is suggested that the thickness of copper coating be defined as 0.5-0.8 mm.

In China, copper clad(copperweld) steel materials are widely used in substation grounding grids in areas with high soil resistivity. Because of the characteristics of UHV project, such as high voltage level, large capacity and short power cut window period, combined with the corrosion intensity of groundwater in the area, copper-clad steel grounding devices have been applied in UHV lines and many UHV lines in China use copper-clad steel materials as grounding bodies.

Comparison between copper-clad steel grounding and traditional hot-dip galvanized steel grounding device

1. Corrosion rate comparision

Annual corrosion rate of grounding materials in some place of Beijing and Tianjin

The test results show that galvanized steel has the most serious corrosion and its corrosion rate is more than 50 times higher than that of pure copper; the corrosion degree of stainless steel is much lower than that of pure copper and copper-clad steel, showing good corrosion resistance; as a copper-steel composite material, the self-corrosion potential of copper-clad steel in soil is basically the same as that of pure copper, and its corrosion rate is the same as that of pure copper; the corrosion rate of the electroplated copper-clad steel with thinner coating is higher than that of the continuous casting copper-clad steel with thicker coating.

2. Analysis and comparison of physical performance in short circuit

If the conductivity of copper were 100% and the conductivity of standard 1020 steel were only 10.8%, the conductivity of copper would be about 10 times that of steel. However, the conductivity of the 30% conductivity copper-clad round wire would be 30%, and the conductivity of the 40% conductivity copper-clad round wire would be 40%, which would be far better than the steel grounding body. Especially under skin effect, the conductivity of copper-plated strands at high frequencies would be much better than that of steel, that is, the conductivity of copper grounding body would be better than that of steel grounding body. The melting point of copper is 1083℃ and the maximum allowable temperature during short circuit is 450℃ ; the melting point of steel is 1510℃ and the maximum allowable temperature during short circuit is 400℃. Therefore, when the grounding body has the same cross section, the copper-clad steel grounding material has better thermal stability.

3. Economic comparison

According to Appendix D of Technical Conditions for Copper-clad Steel for Grounding in Electrical Engineering, the corrosion rates of copper clad steel in different soils are calculated according to the reference values in table. Corrosion rate of pure copper under different soil corrosion grades (mm/a)

The 0.8mm copper plating thickness is enough to meet the requirement of 60 years of service under the grade of III extremely strong corrosion.

The corrosion rate of galvanized steel is nearly 50 times that of copper-clad steel under the same soil conditions, and the grounding body should be overhauled after being used for 3-5 years.

The State Grid has accounted the UHV tower according to the drawings: after the investigation of the market price of material during the construction, the market price of the copper-clad-steel grounding body is calculated at RMB 20 /m, the market price of φ12 galvanized-steel round steel grounding body is calculated at RMB 6 /m and the grounding body laying is calculated according to the grounding construction drawing. During the 30-year whole life cycle, galvanized steel is overhauled every 5 years, of which the cost of material is RMB 20 /m for copper-clad steel and RMB 36/m for galvanized steel, that is, only material cost can be reduced by 80%. Galvanized steel can be overhauled and replaced six times. If the construction cost is RMB 70 /m3 for earthwork and stone works and each base tower is calculated by 23 m3 for excavation, RMB 9660 per base tower will be saved.

Copper-clad steel construction

The horizontal laying of the copper-clad steel grounding device is the same as that of the ordinary galvanized round steel, where only the connection method is changed to hot-melt welding, which has reduced the contact resistance between the joints and is more conducive to the release of lightning current.

Exothermic welding, also known as "aluminum heat welding", is a simple, high-efficiency, high-quality metal joining process that has been mass-produced and used in China in recent years. Exothermic welding uses chemical reaction heat of metal compounds as heat source and through superheated (reduced) molten metal or indirect heating, a certain shape and size of the melted joint is formed in the cavity of the special graphite mould, which meets the engineering requirements, and finally through cooling and condensation, the welding process is realized. At present, exothermic welding has generally replaced the mechanical connection between metals in the past.

Advantages of copper-clad steel

1.It has strong corrosion resistance and will not be disjointed, warped or cracked. The corrosion in the grounding body of the grounding grid is reduced, which has improved the overall operational safety of the equipment;

2. It has good electrical conductivity and stable electrical performance;
3. The copper layer and the steel bar achieve molecular bonding, and the grounding bar will not break down when it penetrates into the soil.
4. The copper-clad-steel grounding material used has high efficiency of reducing the resistance, and the length of the horizontal grounding body is reduced by 1/3 for the design of the high-resistance section, greatly reducing the excavation amount of the earthwork;
5. The design and use of exothermic welding technology is very suitable for the needs of field construction, greatly improving work efficiency and effectively shortening the construction period.

Performance parameters of copper-clad steel wire

Copper layer thickness:0.8mm; tensile strength: greater than 500MPa; copper-clad steel bent 180° without peeling off copper layer.

Specification of 0.8mm series copper-clad round steel: Soft copper-clad round bars are generally packaged in hanks or rolls, 100 meters per roll, easy to transport, suitable for laying of large grounding grids and horizontal grounding lines.

Usage:key projects, large grounding grids and horizontal grounding wires in industries with higher lightning protection requirements, etc.

1. The harmless fuel electric reach forklift will produce exhaust gas in the course of operation, which will not only damage the goods handled to produce strange odor and accumulate soot, but also endanger the health of operators and other people working in the same environment. This is due to the circulation of toxic exhaust gas and dust in the air. For the electric reach forklift, it not only does not produce exhaust gas, but also runs smoothly. At the same time, it has the advantages of ultra-low noise and ultra-low vibration.

2.Low operating costs: With the rising international oil prices, the operating costs of electric reach forklift is very low compared with fuel forklift trucks. The service life of electric reach forklift is longer. Compared with similar fuel forklift trucks, it can save 70% of the cost.

3.Automatic power-off function: When the electric reach forklift is stopped for more than 10 minutes, the power switch can be automatically cut off regardless of whether the key switch is turned off or not. This prevents unnecessary power loss even if the operator forgets to turn off the key switch without using the forklift.

4.Battery compatibility: Each brand of electric reach forklift battery is universal, so the original battery can also be used, so that each component can maintain a longer service life. 

5.Low maintenance costs: Now electric reach forklift uses AC motors without carbon brushes; the reduction of contacts greatly reduces the maintenance costs of electronic components. There is no need to replace electronic fragile parts. So electric reach forklift is more economical.

6. Electric reach forklift  is powered by motor. It uses batteries as its energy source. The carrying capacity is 1.0-4.8 tons, the gantry is 3-6 meters high, and the width of working passage is generally 3.5-5.0 meters. It has no pollution and noise.

According to the structural characteristics, Container Semi-Trailer can be divided into Flatbed semi-trailers and Skeleton Semi-Trailer. The main difference between the Flatbed Semi Trailer and Skeleton Semi Trailer is that the outer frame and diamond pattern floor plate is added. Container Flatbed trailers are mainly used in logistics systems for ships, ports, routes, highways, transfer stations, bridges, tunnels, and multimodal transport. Why are there still many people choose Flatbed Semi-Trailer while it has heavier tare weight than Skeleton Semi Trailer? Flatbed Semi-Trailer has a bottom plate (cargo platform) and can also be widely used to transport ordinary goods. That is the reason why wide flatbed trailer is also very popular for logistic as it has multiple functions. 

Same as Skeleton Semi Trailer, as current standard containers are available in standard sizes of 20 ft, 40 ft, 45 ft, and 48 ft (The world's uniform ISO standard), most of the Flatbed Semi Trailers currently in use are standardized general-purpose products, such as 20, 40, 45, 48-foot fixed-length. Ultraton Series Flatbed Semi Trailer is available with 2-axle 20ft Flatbed Semi Trailer, 3-axle 20ft Flatbed Semi Trailer, 3-axle 40ft Flatbed Semi Trailer, 3-axle 40ft Flatbed Semi Trailer for your choice. Customized design is also welcome. The frame is welded by longitudinal beams, cross beams, front and rear end beams. The longitudinal beams are made of high-quality steel plate submerged arc welded to form I-shaped (main size 450, 500). The cross beams are stamped into C shape by high-quality steel plates. The front and rear end beams are welded in rectangular section. An integral long beam is arranged at the intermediate container locking position to improve the carrying capacity of the container locking device. The whole frame of the frame is processed by shot blasting machine and is assembled and welded on a special positioning gantry. All these details are for durable structure, higher strength and perfect appearance.

Scientists have developed that the boron nitride harder than diamond

Diamonds will no longer be the hardest substance in the world! At present, scientists have artificially synthesized nano-scale cubic boron nitride, which has exceeded the hardness of diamonds.

According to the American Wired magazine, diamonds are not the hardest material in the world. Currently, the Nature magazine published in January pointed out that a new material has surpassed the hardness of diamonds.

A research team from scientists at the University of Chicago and other universities pointed out that the superhard material cubic boron nitride is a form of ultra-hard material that compresses boron nitride particles. Scientists have shown that this transparent material even exceeds the hardness of diamonds, with a Vickers hardness of 108 GPa, while synthetic diamonds have a Vickers hardness of 100 GPa and that the material is twice the hardness of commercial cubic boron nitride.

The biggest secret of this material is the nanostructure. Tian Yongjun and other researchers began to use boron nitride particles like the onion structure (like the Russian doll structure) to compress to 15GPa at 1800 degrees Celsius, that's about 68,000 times the pressure of a car's tires, this crystalline material will recombine to form nanostructures.

Under the nanocrystalline structure, neighboring atoms share a boundary, which is like some apartment house. To make the material harder, scientists reduced the volume of the particles, making it harder to puncture.

Tian explained that the nanostructure makes the material harder to puncture. For boron nitride, the average size of the characteristic strength is 4 nanometers, but the corresponding result is that CBN is very stable at high temperatures.

In the future, the price of the superhard material will be comparable to the current commercial price of less hard CBN, which may be used in machining, grinding, drilling and cutting tools, as well as in the manufacture of scientific instruments.

Plastic welding process of conveyor welding machine is achieved in there ways, softening by external heat source, softening by mechanical motion and softening by electromagnetic action.

Conveyor belt welding machine used in hot plate welding can be said to be the most simple plastic welding technology. It is especially suitable for welding large plastic materials which need large area of welding surface. The general conveyor belt welding machine acts on the waterproof material. The heat produced softens the product. The period is longer. The molten resin will stick to the waterproofing board and it will not be easy to clean. Impurities that affect bonding strength will be formed for a long time. Pressure and time should be strictly controlled to ensure proper melting amount. With different kinds of resin or metal and resin joint, there will be insufficient strength. But the conveyor belt welding machine produced by our company adopts the way that welding device is simple and welding strength is high, and the shape design of products and welding parts is relatively easy. Generally, after melting and softening the two plastic planes to be welded, remove it quickly to electric heating plate and combine the two surfaces and apply force until it is cooling down.

Another way is that when the hot air flow of the welding machine is blowing to the joint area, melt the welding wire between the joint area and the waterproof material and the weld is formed by melting the soldered plastic with the filling material. The welding machine equipment of this method is light and easy to carry but the welding skill requirement of the operator is higher. The two technologies of hot rod and pulse welding are mainly used in the welding of plastic film with small thickness. The two methods are similar. They press two thin films together and use the instantaneous heat generated by a hot rod or nickel-chromium wire to complete the welding.

It is a common fact that we find a wide variety of concrete machines on every construction sites, which make the construction jobs easy, safe and quick. Used concrete equipment has the characteristics of high cost performance. Low risk, low investment cost, high returns.

The armoured components of optical cables are all metal conductors. If the power lines are short-circuited or lightning strikes the metal parts, strong current will be generated to destroy the optical cable line equipment, and even casualties will occur in serious cases.

1. Shock of Lightning

The armoured components of optical cables are all metal conductors. If the power lines are short-circuited or lightning strikes the metal parts, strong current will be generated to destroy the optical cable line equipment, and even casualties will occur in serious cases.

2. Insulation of optical cable lines is poor

If the insulation of communication optical cable line is not done well, the operation strength of optical cable will be greatly reduced due to stress corrosion and static fatigue after the joint box is inundated or in the case of dampness, and cable breakage will occur in serious cases.

3. The influence of external forces

Line faults are often caused by external forces. Because many communication optical cable lines are laid in the field, the general burial standard is deep below the ground, so it can not effectively avoid the damage of many external factors to the optical cable lines.

4. Faults at line joints

Faults are most likely to occur at the junction of the line, because the optical fibers at the junction have no protection to the original cable structure or the protection has been significantly weakened, so the routine operation and protection work can only rely on the junction box, which leads to a great increase in the probability of faults.

What is sewage truck

Sewage truck is a new type of sanitation vehicle that collects, transfers and transports sludge and sewage to avoid secondary pollution. The suction truck can self-prime and discharge, with fast working speed, large capacity, and convenient transportation. The  suction sewage truck is suitable for collecting and transporting liquid materials such as manure, mud and crude oil.

The suction truck adopts the domestic technology-leading suction pump vacuum pump, which has a large suction force and long suction stroke. It is especially suitable for the suction, loading, and unloading of sludge in the sewer, especially for sucking sewage mud, silt, stone, and brick. Large objects such as blocks.

Sewage trucks details

The special part of the sewage truck consists of power take-off, drive shaft, vacuum suction pump, pressure tank body, hydraulic part, pipe network system, vacuum pressure gauge, visual fecal window, hand washing device, etc. Pump and high-quality hydraulic system, the tank can be opened later, and the double top is self-unloading. The dirt in the tank can be directly dumped through the back cover, which is of high vacuum (more suction than the suction truck), large tonnage, high efficiency, and wide usage.

The sewage truck has the same principle as the suction truck, but the sewage truck has different uses from the suction truck. The difference lies in the fact that the tank of the suction truck is a circular tank with a tighter structure, which can provide greater suction force under higher pressure and can be used for collecting and cleaning transportation sewage and sludge.

Since the suction hose is always immersed in the liquid surface, the air in the tank, and it becomes thinner and thinner because it is not replenished, so that the pressure in the tank is lower than atmospheric pressure, and the manure, under atmospheric pressure. , through the suction hose into the tank. Or because the siphon is close to the bottom of the tank, when the air is continuously discharged into the manure tank, it is compressed because there is no way out, so that the pressure inside the tank is higher than the atmospheric pressure, and the manure is discharged by the siphon and the suction hose under the action of compressed air. Outside the can.

The suction truck has the characteristics of high suction efficiency, self-priming, self-discharging, and direct irrigation. Pumping manure tank time: ≤ 5min, suction stroke: ≥ 8m. According to the characteristics of long service life, fast working speed, easy operation, and convenient transportation.
