Disadvantages of overhead insulated cables

　　The allowable current carrying capacity of high-voltage insulated overhead lines is smaller than that of bare wires, because after adding a plastic layer, the heat dissipation of the wires is poor. The shape of overhead insulated wires should be raised by one level compared to usual. If the original 70mm2 wire is used, it should be matched to 95mm2.

　　The diameter of high-voltage insulated overhead lines is relatively large, and with the addition of plastic sheaths, the diameter is one grade larger than that of steel cored aluminum stranded wires with the same cross-section. Although insulated wires have many advantages, their unit cost is higher than bare wires, about twice as high for medium voltage lines and about 25% higher for low voltage lines.

　　Overhead insulated cables have a series of advantages over buried cables, and can also solve some of the problems encountered by conventional bare wires during operation. Therefore, most urban power grid renovations use overhead insulated cables.

　　Overhead insulated cables are mainly used in the construction and renovation of urban distribution networks, and are a type of cable that uses insulated wires instead of bare wires for installation. Not only can it overcome many drawbacks and operational difficulties of overhead bare wires, but it is also relatively inexpensive.

Good insulation performance. Due to the addition of an extra insulation layer, Zhengfan overhead insulated cables have superior insulation performance compared to bare wires, which can reduce the distance between lines, lower the insulation requirements for supporting components, and increase the number of circuits installed on the same pole.

　　The Zhengfan overhead insulated cable has good anti-corrosion performance. Due to the insulation layer on the outer layer, it is less susceptible to oxidation and corrosion than bare wires, and has strong anti-corrosion ability, which can extend the service life of the line.
