Bare ACSS conductors are intended for use as overhead transmission, primary or secondary distribution conductor. This conductor is designed to operate continuously at elevated temperatures, up to 250ºC, without loss of strength. Also, this conductor has less sag than ACSR during increased current loading. It is self-damping if pre stretched during installation, and the final sag values are not affected by the long-term creep of the aluminum wires. ACSS conductors are ideally suited in replacement applications where increased current loading where existing tensions and clearances are required, new applications resulting in a reduction in the number of supporting structures required, and installations where aeolian vibration is an issue.

Annealed aluminum alloy 1350 wires concentrically stranded over a steel wire core. The steel wire core is Class A Zinc coated (Code GA2).

Notes:

Dimensions and weights are subject to standard manufacturing tolerances and are subject to change without notice.
Resistance is calculated using metal conductivity of 63% IACS for EC (1350)at 20ºC and 8% IACS for steel at 20ºC.
Ampacities are based on 75ºC conductor temperature, 25ºC ambient, 2 ft/swind, full sun, an emissivity of 0.5 and a coefficient of solar absorption of 0.5, at sea level.
