Different Types of Overhead Cables

Ⅰ. What are aerial cables

This kind of cables that hang the cable rack on a pole at a certain height from the ground are called aerial cables, which are also called aerial insulated cables. They are aerial wires with insulating layers and protective sheaths. aerial cables are high-voltage transmission lines that are erected in a zigzag pattern over the steel rails in electrified railways for the pantograph. They use special cables whose production process is similar to cross-linked cables. It is a new way of power transmission between aerial wires and underground cables. There are many different aerial cables on the market. let’s take a look.

Ⅱ. Different aerial cables

  1. The aerial cables of model JKLGYJ-1, 1X10/2 are aerial insulated cable with steel core aluminum stranded conductor cross-linked polyethylene, whose pole span can be 20 meters. JKLGYJ-11X10/2 long-term allowable current carrying capacity is 75A. Pay attention to the local power supply voltage. If it is relatively low, consider using aerial insulated cables with the model JKLGYJ-1, 1X16/3 (reference current carrying capacity 100A) because the line loss of the aluminum core wire is larger.
  2. Do not use wires to pass through pipes, which is not conducive to the heat dissipation of cables. VLV, 3X10+1X6 or VLV, 0.6/1kV, 3X16+1X10 aluminum core PVC insulated and sheathed aerial power cables can be used directly, and the wire rope is drawn by the pole, and the wire rope is tied with a cable hook or insulated wire. The reference current carrying capacity of VLV, 3X10+1X6 is 40A, and the reference current carrying capacity of VLV, 0.6/1kV, 3X16+1X10 is 54A. The price of the two aluminum core cables is not too high, basically the same.
