Advantages and characteristics of overhead insulated cables

Overhead insulated cables are mainly used for overhead fixed laying, household lines and other places. Their insulation materials are special overhead insulated cable materials for weather resistance, so overhead insulated cables have the advantages of simple structure, safety and reliability, excellent mechanical and physical properties and electrical properties, environmental resistance and UV resistance. Because their insulation adopts special overhead insulated cable materials for weather resistance, the long-term allowable working temperature of the cable is as high as 70 ℃ or 90 ℃, And the electrical insulation performance is excellent, and the volume resistivity reaches 1.0 × Above 1012 Ω· m; In laying, the use of overhead insulated cables 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.

The new urbanization and new rural construction in countries all over the world, especially in developing countries, are accelerating. The new overhead insulated cable is of great significance to optimize the line structure, save energy and reduce consumption, and reduce cost. It is the preferred product for building a green distribution network. opgw wire
