STER-ACSSTM

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

Aluminium Conductor Steel Supported

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.

Ideal for Reconductoring & New Lines.

● Increase capacity of lines while maintaining Electrical clearance.
● Can be Deployed in Existing Structures or can reduce strain on structures, increasing life.
● 100% more capacity building towards future demands.

 

Benefits

● 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.

Note: The Catalogue conductor Parameter are informative and can be customized as per Project Requirements.

Assumptions: Ampacity is calculated based on, 45°C ambient temperature, 0.56 m/s wind velocity, 0.8 as coefficient of solar absorption, 0.45 as coefficient of emissivity and 1045 W/sq.m coefficient for solar radiation, 0 m Elevation. Non-Specular (NS) Dull Finish Conductor can be available on special requirement.
