ACSS-Aluminum Conductor Steel Supported

Application

Aluminum Conductor Steel Supported (ACSS) is a composite concentric-lay stranded conductor with one or more layers of hard drawn and annealed 1350-0 aluminum wires on a central core of steel. ACSS are suitable for operating at high temperature without loosing the mechanical properties. The final sag-tension performance is not affected by the long term creep of aluminum.

 Construction

ACSS, a non-homogenous conductor, is a concentric-laystranded conductor made from round aluminum 1350-O wires and round, coated steel core wire(s). Steel wires are coated with Class A coating of zinc – 5% aluminum mischmetal alloy. Other Classes of coatings are also available for additional protection from corrosion. Standard, High, Extra and Ultra High Strength steel are also available.
 

Features

ACSS conductors can be operated up to 250 °C.
ACSS conductors carry more current than ACSR conductors.
ACSS conductors are prone to resist the effects of aeolian.
 

Standards

ASTM B 609: Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
ASTM B 498: Standard Specification for Zinc-Coated (Galvanized) Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR).
ASTM B 856: Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Supported (ACSS).
