Brief introduction

As the grid density increases, and new transmissionline costs and environment problems are becoming hard to

control. To improve the transmission capacity of power

grids on the existing basis becomes the most effective way

to deal with the problem. Without increasing the conductorsection, the new overhead wires heat-resistant aluminum

alloy conductor and high strength aluminum alloy

conductor can increase transmission capacity in the most

economical way.

Manufacture process

Composition and classification ofaluminum alloy conductorIn the process of casting and rolling aluminum, add some

rare earths and some other alloy elements such as Mg Si ZrMn etc..According to its characteristics, it is divided into Al-Mg-Si alloy conductor and heat-resistant aluminum alloy .

Aluminum alloy rod

The heat-resistant alloy conductor and high tensile

strength alloy conductor can increase the capacity by 1-2

times of normal ACSR capacity . Such conductors are

suitable for some new high-capacity T/L or for some

expansion of old lines and transformer substation andsome large cross lines.
