ACSR

Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding for desired strength to be achieved without sacrificing ampacity.

Construction

What it's built from

Conductor: Aluminum alloy 1350-H19 wires, concentrically stranded around a steel core.
Core options: Class A, B or C galvanizing; aluminum coated (AZ); or aluminum-clad steel core (AL).
Corrosion protection: Grease applied to the core or infusion of the complete cable with grease.
Finish: Also available with Non Specular surface finish.
