铜包铝线代替铜线作为编织屏蔽材料的可行性分析

Feasibility Study on the Use of Copper-Clad Aluminium Conductor as the Braiding Wire of Screen Braid Instead of Copper Wire

本文对电力系统中二次保护系统用编织屏蔽控制电缆采用铜包铝线代替铜线作为编织屏蔽材料的性能进行了技术分析,认为铜包铝线代替铜线作为编织屏蔽材料的技术是可行的,它可以节省大量的铜资源,创造可观的经济效益和社会效应。

This paper makes a technical analysis of the performance of the copper-clad aluminium conductor as the braiding wire of the screen braid instead of copper wire in the screened control cable used in the secondary protective system of power system. The author holds that it is technically feasible to replace copper wire with copper-clad aluminium conductor to make braided screen, which saves large amount of copper thus making remarkable economic and social benefits.
