477 Hawk ACSR - Aluminum Conductor Steel Reinforced

Allowable Ampacity for 477 HAWK ACSR: 659 Amps

Applications:

ACSR wire, or Aluminum Conductor Steel Reinforced cable, is an electrical cable mainly used for distribution services as well as bare overhead transmission, both primary and secondary, in various industrial settings, including construction. ACSR cable is especially suitable for line design due to its steel core strand, which increases the strength of the cable without sacrificing its ampacity, yet affects the ACSR wire price. The aluminum alloy conductor in ACSR wire prevents overheating and allows for extra flexibility of the electrical wire.

Application:

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

Conductors:

Aluminum alloy 1350-H119 wires, concentrically stranded around a steel core available with Class A, B or C galvanizing; aluminum coated (AZ); or aluminum-clad steel core (AL). Additional corrosion is available through the application of grease to the core or infusion of the complete cable with grease.
