Application Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR Offers optimal strength for line design. Variable steel core stranding enables desired strength to be Achieved without sacrificing ampacity. Construction ACAR has aluminium 1350 H-19 wires concentrically stranded around a 6201-T81 aluminium Alloy core. Typically, the 6201-T81 is the conductor core, but in certain designs, the 1350 H-19 And the 6201-T81 wires may be stranded in the same layer.
