| Description : |
ACS = (Aluminium Clad Steel) is a high strength steel wire with a thick aluminium coating.
Aluminium Clad Steel (“ACS”) wire consists of a central steel core with a layer of highconductivity aluminium extruded over it. The aluminium layer forms a seamless metallurgical tie with the steel wire to guarantee permanent bonding during rewinding and stranding.
The aluminium layer thickness is atleast 10% of the wire radius and approximately 25% of the cross-sectional area. Conductivity is proportional to the aluminium layer thickness. Conductivities ranging from 20% to 40% IACS are available.
Aluminium Clad Steel cable is well known for its combination of corrosion resistance, high strength and superior electrical conductivity. These properties make it an excellent choice either as overhead static wire (ground wire, “OPGW”) It can also be used as core in ACSR conductors. |
