ACS-Aluminum Clad Steel Wire
Aluminum Clad Steel (ACS) is a high-strength steel wire with a thick aluminum coating. The ACS wire consists of a central steel core and a layer of high-conductivity aluminum extruded onto it.
Construction
Aluminum clad steel wire is a kind of bimetallic wire that aluminum covers the steel core continuously and evenly.
Application
ACS wire is commonly used in overhead power transmission and distribution lines. It is also used in grounding systems and other applications where corrosion resistance is important.
Feature
The advantages of ACS wire is that it has a lower thermal expansion coefficient than aluminum wire, which means it is less likely to sag or break due to temperature changes. Additionally, the steel core helps to reduce the overall weight of the wire, making it easier to handle and install.
