Aluminum Clad Steel Wire / Alumoweld (ACS/AW)

Aluminum coated steel wire Conductor for Power Transmission Line

Application

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.

Standards

AW or AS or AC.
AW : Aluminum-clad steel wire as per ASTM B 502 Standard.
AS : Aluminum-clad steel wire as per IEC 61232 Standard.
AC : Aluminum-clad steel wire as per AS 3607 Standard.
The covered aluminum steel wire for compression, internationally known as Alumoweld or ACS, is a wire of high resistance whose cover is carried through an extrusion process, that adheres the aluminum by pressure and heat.
Manufacture of bare overhead conductor, OPGW, ground wire,Overhead ground wire, messenger wire, guy wire, formed wire for protecting, terminating and splicing transmission and distribution lines,shield wire protecting transmission lines against lightning damage fence, barber wire and hardware.
Alumo-clad steel wire and strand is used by power utilities as well as formed wire and optical ground wire manufacturers.

Aluminum Clad Steel Wire Alumoweld(ACS-AW)Structure

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.

Characteristics

ACSR/AW Core Wire and Strand
Its high strength, excellent conductivity, impressive corrosion resistance and compatibility with solid aluminum wire make aluminum clad steel products highly desirable as a reinforcing material for ACSR conductors (ACSR/AW).

Formed Wire
Aluminum coated products are made with a special, malleable steel core in its formed wire solution. When used with other connectors and anchors, you guarantee a metallurgical compatibility that eliminates conflicts between dissimilar metals and matches the life expectancy of the conductor or guy wire.

Guy Wire
Aluminum guy wire is non-rusting, high-strength for electrical distribution and transmission lines, communications and signal lines, antenna towers, masts, stacks and other structures. The high tensile strength of this lightweight strand is permanently protected against corrosion by a thick cladding of aluminum.

Messenger Wire
Communications cables require the same superior grade of messenger strand as power cables. Messenger wire ensures a long life, will not rust and maintains its original strength.

Overhead Ground Wire
Aluminum clad steel overhead ground wires offer protection against lightning for transmission lines carrying large blocks of power while providing a combination of conductivity, corrosion resistance and high strength.
