Sterlite® Aluminium Conductor Steel Supported (ACSS) conductor is a composite concentric lay-stranded conductor consisting of a stranded steel central core with one or more layers of 1350-0 (High Temperature) aluminium wires
Sterlite® Aluminium Conductor Steel Supported (ACSS)
ACSS conductors can be used as a low loss solution, as part of efficient transmission networks. These conductors are suitable for lines that transmit very high or fluctuating loads.
● Improved self-damping characteristics and high degree of resistance to vibration fatigue.
● Can operate continuously at high temperatures up to 250°C (482°F) with appropriate steel core coating v/s 100°C (212°F) for standard ACSR, hence can carry twice as much current as ACSR conductor.
● No creep.
● Less susceptible to Aeolian vibration fatigue due to very low mechanical load on the annealed aluminium wire.
● Requires conventional installation techniques.
● Allows for lower overall transmission cost.
