ACS — Aluminum Clad Steel Wire

The aluminum clad steel wire internationally known as Alumoweld or ACS is widely used in long-span transmission line, coastal areas and island as well as other hot and humid regions, salt fog regions and heavily polluted regions where the high corrosion resistance strand is needed.

  • Aluminum clad steel wire is a kind of bimetallic wire that aluminum covers on the steel core continuously and evenly.
  • Basic design to ASTM B416 standard

Product Description

Application

The aluminum clad steel wire internationally known as Alumoweld or ACS is widely used in long-span transmission line, coastal areas and island as well as other hot and humid regions, salt fog regions and heavily polluted regions where the high corrosion resistance strand is needed.

It is used as the core of ACSR/AW, overhead ground conductor, extra high voltage overhead conductor, optical fiber composite overhead ground line, self-damping conductor line, bare overhead conductor, OPGW, ground wire, messenger wire, guy wire formed wire for protecting, terminating and splicing transmission and distribution lines, fence, barber wire and hardware, etc.

Standard

Basic design to ASTM B416 standard

Construction

Aluminum clad steel wire is a kind of bimetallic wire that aluminum covers on the steel core continuously and evenly. Compared with ordinary aluminum cable steel reinforced, the conductor weight is 5% lighter, current-carrying capacity is 2-3% higher and power loss decreases 4-6%. Thus, the service life is long and it adds none erection cost.
