ACSR Conductors

ACSR : ALUMINUM CONDUCTOR, STEEL REINFORCED

ACSR consists of a solid or stranded steel core with one or more layers of high purity Aluminium wires wrapped in spiral. The core wire zinc coated (galvanized) steel or if required aluminium coated (aluminized) steel for certain applications.

Galvanization is generally of thin coating and is applied to protect the steel from corrosion. The central steel core provides additional mechanical strength and, hence, sag is significantly less than all other aluminium conductors.

ACSR with higher steel content is selected where higher mechanical strength is required, such as river crossing. ASCR conductors are very widely used for all transmission and distribution purposes requiring longer span.
