What are the common models of overhead cables?

In the life, an overhead insulated cable is often seen, that is, a cable construction method in which the cable is placed on a pole that moves from the ground. Because the overhead cable erection is relatively simple and the cost is relatively low, the use is still extensive. So what are the common model specifications for overhead insulated cables?

1, JKV JKLV JKY JKLY JKYJ JKLYJ copper, aluminum core PVC insulated aerial cable copper, aluminum core polyethylene insulated aerial cable copper, aluminum core XLPE insulated aerial cable, used for overhead fixed laying lead line.

2, JKYJ JKLYJ JKTRYJ JKY JKLY JKTRY JKGYJ JKLGYJ copper, aluminum XLPE insulated aerial cable soft copper core XLPE insulated aerial cable copper, aluminum core polyethylene insulated aerial cable soft copper core PE insulated aerial cable copper core twist Wire cross-linked polyethylene insulated aerial cable aluminum core stranded XLPE insulated aerial cable for overhead fixed laying, soft copper core products for transformer down conductor. When the cable is overhead, consider keeping the cable and trees at a certain distance; when the cable is far away, allow the cable and trees to come into contact frequently. Steel core type overhead cable is used for mountainous areas and rivers are laid across.

3, JKLY / B aluminum core color cross-linked polyethylene insulated aerial cable, used for overhead fixed laying cable erection, should consider the cable and trees to maintain a certain distance; cable running, allow cables and trees to contact frequently.

4, JKLYJ / QJKLY / Q aluminum core light XLPE insulated aerial cable aluminum core light polyethylene insulated aerial cable, used for overhead fixed laying cable erection, should consider cable and tree to maintain a certain distance; cable running, allow cable Short-term contact with trees.

Steel-cored aluminum stranded conductor XLPE insulated aerial insulated cable (model JKLGYJ-1, 1X10/2), the pole bar distance can be 20 meters, JKLGYJ-11X10/2 long-term allowable current capacity is 75A, considering the distance Line loss, but enough. Note that the local power supply voltage is not high. If it is relatively low, consider using JKLGYJ-1, 1X16/3 (reference current carrying capacity 100A), mainly considering the line loss of the aluminum core wire.
