The ACSS/GA conductor is a kind of High-Temperature Low-Sag conductors. The most important difference between ACSS conductors compared to ACSR conductors is the use of 1350-O annealed aluminum wires instead of hard-drawn 1350-H aluminum wires. Annealed aluminum wires have higher electrical conductivity and lower electrical resistance. The best advantage of annealed aluminum wires compared to 1350-H19 aluminum wires is their higher thermal resistivity (up to 200 °C).

Description

The ACSS/GA conductor is a kind of High-Temperature Low-Sag conductors. The most important difference between ACSS conductors compared to ACSR conductors is the use of 1350-O annealed aluminum wires instead of hard-drawn 1350-H aluminum wires. Annealed aluminum wires have higher electrical conductivity and lower electrical resistance. The best advantage of annealed aluminum wires compared to 1350-H19 aluminum wires is their higher thermal resistivity (up to 200 °C). ACSS/GA conductor's core is composed of galvanized steel wires. The galvanized coating protects the core of the conductor from corrosion and harsh environmental conditions.

ACSS conductors find application in both overhead distribution and transmission lines. Comprising annealed aluminium strands with lower electrical resistance compared to standard aluminium strands but possessing lower mechanical strength, these conductors compensate for the reduced mechanical strength by incorporating high-strength steel wires in their core. The combination of high-strength steel wires with annealed aluminium layers reduces sag, increases current-carrying capacity, and diminishes line losses. Engineered to operate continuously at high temperatures up to 250 °C without compromising strength, ACSS conductors exhibit less sag under emergency electrical loads compared to typical ACSR conductors.
