Overhead Cable Introduction

Overhead cable (full name of overhead insulated cable) is a kind of special cable which is equipped with insulation layer and protective outer layer and is made by using the process similar to cross-linking cable production. It is a new transmission mode between overhead wire and underground cable. Overhead cables are single-core, according to its structure can be divided into hard aluminum wire structure, hard-drawn copper wire structure, aluminum alloy wire structure. Steel or aluminum core support structure and self-supporting three-core structure (wire core can be hard aluminum or hard copper wire) and so on. With high reliability of power supply, power supply security, erection and maintenance convenience and economy and other major features. Its main technical parameters include weatherability, insulation level, inner and outer semiconductive shields. Overhead cable in a wide range of domestic and international transmission.

General overhead cable is single core, according to its structure can be divided into hard aluminum wire structure, hard pull copper wire structure, aluminum alloy wire structure. Steel or aluminum core support structure and self-supporting three-core structure (wire core can be hard aluminum or hard copper wire) and so on.

Hard aluminum wire structure of light weight, moderate tension, the cable is easy to bend, easy to install, and the project cost is low, you can install it on the existing tower to use, and now the general renovation or new construction more use of this.
