Composite insulator composite polymer insulator composite silicone insulators are a special type of insulation control that can play an important role in overhead transmission lines.

Composite insulators are also known as synthetic insulators, non-porcelain insulators, polymer insulators, rubber insulators, etc. The main structure is generally composed of a shed skirt, a FRP core rod and an end fitting. The shed skirt is generally made of organic synthetic materials, such as ethylene propylene rubber, high temperature vulcanized silicone rubber, etc.; FRP mandrels are generally made of glass fiber as a reinforcing material, and a oxidizing resin as a base material; The end fittings are generally carbon steel or carbon structural steel coated with hot zinc-aluminum.

Classification of Silicone Rubber Insulators silicone rubber insulator silicone composite insulators

Composite insulators can be divided into: line composite insulators and power stations, electrical composite insulators. It can also be divided into rod-shaped suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof partial composite insulators, and so on.

Advantages of Composite Silicone Insulator

Small size, easy to maintain;

Light weight, easy to install;

High mechanical strength, not easy to break;

Excellent seismic performance and good stain resistance;

Fast production cycle and high quality stability.

End Fitting Structure

Composite insulators vary in their structure depending on the characteristics of use. In addition to meeting the tensile strength, meeting the requirements, and reliably connecting with the mandrel, the design of the metal tip also needs to meet the special requirements for application under high voltage. Composite insulators are generally made in the shape of a rod with a small capacitance. Therefore, the voltage distribution on the surface of the insulator is very uneven. Thus, in normal operation, the generated corona will be harmful, so it is necessary to use a pressure equalization measure. In addition, the synthetic insulating material cannot withstand an electric arc of several tens of kiloamperes. In the event of a short circuit fault, it will burn the umbrella near the wire and the tower, so arcing is required. At home and abroad, the method of adding a pressure equalizing ring is generally adopted to uniform the end electric field, weaken the corona, and lead to the fault arc.

The voltage equalizing ring of the composite insulator is a component of the composite insulator. Its function is to control the electric field strength inside the insulator, avoid internal partial discharge, reduce the local electric field strength of the external surface, especially the surface of the metal connecting part, and reduce the radio interference. Leading the power frequency arc to avoid burning the surface of the insulator and minimizing the local electric field strength near the end surface to improve its anti-smudge performance.

In addition, they are continuing to evolve. Since companies or customers have different requirements and demands, different types of rapid prototyping processes will be chosen. So how does rapid prototyping work? Reading the following contents and you will know which rapid prototyping service suits you best.

 

SLA（StereoLithography）

• Description: SLA is a photo-curing molding technology, which refers to the method of forming three-dimensional solid layer by layer through the polymerization reaction of liquid photosensitive resin by ultraviolet irradiation. The work piece prepared by SLA has high dimensional accuracy and is the earliest commercial 3D printing technology.
• Printing Material: Photosensitive Resin
• Strength: photosensitive resin is insufficient in toughness and strength and is easily broken. At the same time, under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.
• Features of finished product: SLA printed workpieces have good details and smooth surface, which can be colored by spray painting and other processes.

 

Selective Laser Sintering (SLS)

• Description:SLS is a selective laser sintering technology, similar to SLM technology. The difference is the laser power. It is a rapid prototyping method that uses infrared laser as a heat source to sinter powder materials and form three-dimensional parts layer-by-layer.
• Printing Material:Nylon powder, PS powder, PP powder, metal powder, ceramic powder, resin sand and coated sand (common printing materials: nylon powder, nylon plus glass fiber)
• Strength:material performance is better than ABS products, and the strength and toughness are excellent.
• Features of finished product:the finished product has superior mechanical properties and is suitable for direct production of measurement models, functional models and small batch of plastic parts. The disadvantage is that the precision is not high, the surface of the prototype is relatively rough, and it is generally required to be polished by hand, sprayed with glass beads, ash, oil and other post-processing.

Fused Deposition Modeling (FDM)

• Description: FDM is a melt lamination technology, that uses high temperature to melt materials, extrudes them into filaments through the print head, and builds up on component platform. FDM is the simplest and most common 3D printing technology, which is commonly used in desktop 3D printing devices.
• Printing Material：usually ABS or PLA wire
• Strength: PLA is brittle,its surface hardness is higher, and it is easier to break when bending. ABS parts are more resilient than PLA parts, and are easy to bend rather than break under pressure. Moreover, ABS has higher strength, better plasticity, and easier post-processing.
• Features of finished product: the printing layer is thick, the precision is poor, and the stratification of the surface is very obvious. Under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.

 

CNC

• Description: CNC machining is a subtractive manufacturing process in which the software control system issues instructions to make the tool perform various required movements. In this process, various precision tools are used to remove the raw materials and make parts or products.
• Materials: CNC processing materials are quite extensive, including plastics and metals. Plastic hand model materials are: ABS, acrylic, PP, PC, POM, nylon, bakelite, etc.; Metal hand model materials are: aluminum, aluminum Magnesium alloy, aluminum zinc alloy, copper, steel, iron, etc.
• Strength: different materials have different strengths and are difficult to list
• Features of finished product: CNC machined parts have a smooth surface, high dimensional accuracy, and the best compactness, and there are a variety of post-processing options.

 

Vacuum Casting

• Description: vacuum casting technology is to use the prototype (rapid prototyping parts, CNC hand parts) to make a silicone rapid prototyping mold under vacuum condition. It also uses PU, ABS and other materials to pour, so as to clone the same copy with the product prototype.
• Material: ABS, PU, PVC, silicone, transparent ABS
• Strength: the strength and hardness are lower than the CNC hand parts. Common PU material is relatively brittle, toughness and high temperature resistance are poor. ABS has higher strength, better plasticity, and easier post-processing.
• Features of finished product: easy to shrink and deform; the accuracy is generally only 0.2mm. In addition, the vacuum casting hand parts can only resist high temperature of about 60 degrees, and is lower than CNC hand parts in strength and hardness.
