Aluminum-cored steel-supported ACSS cables for overhead transmission lines.
ACSS Cable is a concentric stranded composite conductor consisting of a galvanized steel-stranded core and one or more layers of annealed or softened 1350-0 aluminum. The steel core is Class A galvanized zinc-coated steel that carries most or all of the mechanical loads of the conductor due to the annealed or softened aluminum. The steel core has high strength as required.
ZMS produces ACSS cables that can be operated continuously at temperatures up to 250°C without loss of strength, which also results in a significant increase in the ACSR’s current-carrying capacity. The ACSS is self-damping, with a lesser plunge under emergency electrical loads than the ACSR, and its final plunge is unaffected by the long-term creep of the aluminum.
These advantages allow ACSS cables to be used in new line applications. In applications where structures can be optimized due to reduced conductor sag or where high emergency loads may be required; or in lines where wind vibration is a problem. ACSS can be used to conduct an existing line to allow increased current using existing gaps and tensions.
Types of VERI ACSS Cable
ACSS—Aluminum Conductor Steel Supported
ACSS is a concentric stranded composite conductor made of a galvanized steel strand core and one or more layers of annealed or soft 1350-0 aluminum.
The steel core is Class A galvanized steel that can withstand most or all of the mechanical load of the conductor due to the use of annealed or soft-tempered aluminum. High-strength steel core available on request.

Aluminum Conductor Steel Supported cables are used for overhead transmission lines. And ACSS is designed to operate continuously up to 250ᵒC, even higher temperatures. But they can not destroy the strength of the cable. So it can improve the current carrying capacity of ACSS cable. The ACSS is self-damping, with less sag under emergency electrical loads than the ACSR. And its ultimate sag is not affected by the long-term creep of PF aluminum. These advantages make the ACSS very useful in new-line applications.
ACSS/TW—Aluminum Conductor Steel Supported
Steel Support (ACSS/TW) is a concentrically stranded conductor with one or more layers of trapezoidal hard-drawn and annealed 1350-0 aluminum wire on a central core of steel.
Designed for continuous operation at high temperatures, ACSS/TW has less sag under emergency electrical loads than ACSR/TW. It has excellent self-damping properties, and its ultimate sag is unaffected by long-term creep in aluminum.
STANDARDS&REFERENCES: ASTM B 857ASTM B609/ASTM B851/ASTM B856
ACSS/TW can be designed to have the same aluminum cross-sectional area as standard ACSS, resulting in smaller conductor diameters but reducing wind load parameters. Or diameters equal to that of standard ACSS, resulting in significantly more high aluminum area, lower conductor resistance, and higher current rating.
