ACS Alumoweld Aluminium Clad Steel Wire IEC 61232 Standard

Our ACS Alumoweld Aluminium Clad Steel Wire is manufactured in strict accordance with the IEC 61232 standard, ensuring high-quality performance for overhead transmission and distribution lines. This wire features a steel core clad with a layer of aluminum alloy (Alumoweld), combining the high tensile strength of steel with excellent electrical conductivity and corrosion resistance of aluminum. The Alumoweld construction provides reliable mechanical strength and excellent electrical performance, making it ideal for long-span overhead power applications. Conformance to IEC 61232 guarantees that the wire meets international standards for dimensions, mechanical properties, and electrical characteristics, ensuring durability and safety in demanding environments.

ACS, Alumoweld Aluminum Clad Steel Wire ACS APPLICATION

ACS– The full name: Aluminum Clad Steel Wire. The aluminum clad steel wire 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.

FEATURES

Aluminum clad steel wire is perfectly combined of aluminum and steel core, and there will be no flaking off during the heat treatment or mechanical workout. The aluminum clad steel wire is the best new bimetallic wire instead of pure copper wire.

A high strength steel wire with a 25% thick cross-section ratio of aluminum cladding creates a high electrical conductivity, highly corrosive resistant, and a thermal stability for high temperature operation and all with a lighter weight.
