Product Details

ACSS/AW, Aluminium Conductors Steel Supported (ASTM B 856)

Features

ACSS has at least 63.0% IACS conductivity due to their "deadsoft" (fully annealed) aluminum strands.

For the same reason, ACSS cables can be operated at temperatures of maximum 250 °C without loss of strength. Since the mechanical tension applied to the aluminum strands is low, the ACSS self damping

characteristic is high. This allows ACSS cables to be installed at high unloaded tensions without the need for separate Stockbridge dampers.

Application

Generally used as bare overhead transmission lines.
