Description
Overhead transmission line
Overhead fixed laying and access lines
Product Characteristics
The overhead insulated cable has the advantages of simple structure, safety and reliability, excellent mechanical and physical properties and electrical properties, environmental resistance and ultraviolet resistance, etc., because its insulation is weather-resistant special overhead insulated cable material, the long-term allowable working temperature of the cable is as high as 70ºC or 90ºC, and the electrical insulation performance is excellent, and the volume resistivity is more than 1.0×10^12Ω·m; In laying, the overhead insulated cable can reduce the laying gap, save the line corridor and reduce the voltage drop. In use, it can reduce the occurrence of power supply accidents and ensure personal safety.
