Specification

397.5 Lark ACSR - Aluminum Conductor Steel Reinforced

Allowable Ampacity for 397.5 LARK ACSR: 594 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.
