- power cable
The power cable is used to transmit and distribute high-power electrical energy in the main line of the power system, including power cables of various voltage levels and insulations ranging from 1 to 330KV and above.
According to voltage levels, power cable can be divided into low-voltage cables, medium-voltage cables, and high-voltage cables. According to the insulation conditions, it is divided into plastic insulated cables, rubber insulated cables, mineral insulated cables, etc.
- Overhead insulated cable
Overhead cables are also very common, and their characteristic is that they have no sheath. Many people have three misunderstandings about this type of cable.
First, its conductor is not only aluminum but also copper conductors (JKYJ, JKV) and aluminum alloys (JKLHYJ). Now there is also steel core aluminum stranded overhead cable (JKLGY).
Second, it is not only single-core, the common ones are generally single-core, but it can also be stranded with several conductors.
Third, the voltage level of overhead cables is 35KV and below, not 1KV and 10KV.
- Control Cable
The structure of this type of cable is similar to that of a power cable. The feature is that it only has a copper core instead of an aluminum core cable. The conductor cross-section is small and the number of cores is large.
It is suitable for stand-alone control or unit equipment control of power stations, substations, mines, petrochemical enterprises, etc., with AC rated voltages of 450/750V and below.
- Special cables
Special cables are cables with special functions, including flame-retardant cables (ZR), low-smoke and halogen-free cables (WDZ), fire-resistant cables (NH), explosion-proof cables (FB), water-blocking cables (ZS), etc.
Flame-retardant cables (ZR), low-smoke halogen-free cables (WDZ): mainly suitable for important power and control systems. When the line encounters a fire, the cable can only burn limitedly under the action of the external flame, and there are few harmful gases (halogen) in the smoke.
When the external flame disappears, the cable can be extinguished by itself, so that minimize the fire damage to the human body and property. Therefore, this kind of cable is widely used in important places such as petrochemical, metallurgy, high-rise buildings, and densely populated places.
