ACS Alumoweld Aluminium Clad Steel Wire

Shape of conductor: circular and sectional

Conductor Material: Aluminum Clad Steel

Insulation: N/A

Standard: IEC 61232

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.

GUY WIRE(galvanized steel guy wire):

Galvanized Steel Guy Wire which Concentric-lay stranded conductors made of Zinc-coated Steel wires. Commonly used for overhead ground/shield wire, guys and messengers, and for steel core in ACSR conductors.

GSW-Galvanized Steel Wire Conductor IEC 61089 Standard

Shape of conductor: circular and sectional

Conductor Material: Galvanized Steel Wire Stranded

Insulation: N/A

Standard: IEC 61089

GSW WIRE APPLICATION:

Galvanized steel wire also names GSW Wire ,Messenger Wire, Overhead Ground or Stay Wire, Guy Wire, GI Wire
Galvanized steel strand wire can be used as ground wire of overhead line, but also can be used as structural cable, supporting cable, cable, block cable and cable reinforcement core. It is made of wire twisted together. There are mainly ASTM standards, BS standards, IEC standards and other production standards. It is widely used in energy, construction, bridge, water conservancy and geotechnical engineering.

STANDARD :

ASTM A475, ASTM A363, IEC 61089 BS183:1972 and ect.Other International Standard.

CONSTRUCTION :

1.The single wires are concentrically stranded and wrapped helically around a central wire.
2.Zinc-coated grade of steel strand wire /guy wire : Class A ,Class B and class C.
Concentrically stranded Galvanized steel wire strand available in class “A”, “B” and “C” galvanizing, “A” being the least heavy and “C” being the most heavy.
