Intrduction :

ACSS is a composite concentric-lay stranded cable. The steel strands form the central core of the cable around which is stranded one or more layers of aluminum 1350-O wires. ACSS conductors are manufactured in accordance with the requirements of the latest applicable issue of ASTM specification B856. The "O" temper of the aluminum, a fully annealed or soft temper, causes most or all of the mechanical load on ACSS to be carried by the steel. The steel core may consist of 7, 19, 37 or more wires. Class A zinc coating is usually adequate for ordinary environments.

STANDARDS
ACSS conductor meets or exceeds the following ASTM standards:
lB-341 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced.

lB-500 metallic Coated Stranded Steel Core For Aluminum Conductors, Steel Reinforced.

lB-609 Aluminum1350 round Wire, Annealed and Intermediate Tempers, for Electrical Purposes

lB-802 Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel

Reinforced.

lB-803 High-Strength Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum and

Aluminum-Alloy Conductors, Steel Reinforced.

lB-856 Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Supported(ACSS)


Applications

ACSS is used for overhead distribution and transmission lines. It is designed to operate continuously at elevated temperatures up to 250°C without loss of strength; it sags less than a comparable ACSR under electrical loadings; it is self-damping if prestretched during installation; and its final sags are not affected by long term creep of aluminum. The advantages make ACSS especially useful in reconductoring applications requiring increased current with existing tensions and clearances, new line applications where structures can be economized because of reduced conductor sag, new line applications requiring high emergency loadings, and lines where aeolian vibration is a problem.
