VERI CABLE ACSS is a concentric-lay stranded composite conductor made up of a core of galvanized steel strands and one or more layers of annealed or soft 1350-0 Aluminum. The steel core wire is Class A galvanized zinc-coated steel which, due to the annealed or soft temper Aluminum, carries most or all of the mechanical load of the conductor. Upon request the steel core is available in High strength.Aluminum-cored steel-supported ACSS cables for overhead transmission lines.
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.

APPLICATION
Aluminum conductor steel supported (ACSS) cable is used for overhead transmission lines. ACSS is designed to operate continuously at higher temperatures up to 250℃ without loss of strength, which allows for a significant increase in current carrying capacity over ACSR. ACSS is self-damping, sags less than ACSR under emergency electrical loadings, and its final sags are not affected by the long-term creep of aluminum. These advantages make ACSS useful in new line applications where structures can be optimized due to the reduced conductor sag, where high emergency loads may be required; or in lines where Aeolian vibration is a problem. Existing lines can be re-conductored using ACSS to allow for increased current using the existing clearances and tensions.
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
APPLICATION
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.

VERI Cable is founded by one of the most professional manufacturers. We specialize in producing and exporting all kinds of wires and cables. We have advanced tech staff, advanced equipment, and 30 years of experience in engineering. Welcome to visit at any time. Since we were founded, we have built favorable business relationships with many customers from all over the world.
For conductors suitable for overhead transmission (AAC AAAC ACSR ACAR ACSR/AW)/ABC/Concentric cables (Aluminum or Copper), ZMS usually uses standard wooden drum packaging, but we can also design different types of packaging according to customer requirements.
VERI Cable specializes in overhead cable, control cable, submarine cable, and cable accessories. HTLS conductors are a new type of overhead cable. And HTLS conductors include ACSS wire, ACCC cable, GAP type conductor, etc. As a professional cable manufacturer, we provide high-quality HTLS conductors. And we are a worldwide supplier of cable products. So our HTLS cables have passed the IEC, ASTM, and other international certifications.
