Aluminum Conductor Steel Supported-Trapezoidal Wire(ACSS TW)
ASTM B857 Standarded ACSS / TW Conductor
Application
Aluminum conductor steel supported-trapezoidal wire is widely used in overhead distribution and transmission lines. This product has the special design of equal area and equal diameter. The equal area design enables equal capacity to go through smaller diameter conductor compared with a standard ACSS conductor. The equal diameter design allows more capacity to go through an equal diameter conductor compared with a standard ACSS conductor.

Standards
ACSS/TW conductor meets or exceeds the following ASTM specifications:
B500 Metallic Coated Stranded Steel Core for Aluminum Conductors, Steel Reinforced.
B609 Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
B802 Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced.
B803 High-Strength Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum and Aluminum-Alloy Conductors, Steel Reinforced.
B857 Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Supported (ACSS/TW).
Construction
ACSS/TW is a composite concentric-lay-stranded conductor. Steel strands form the central core of the conductor with one or more layers of 63% minimum average conductivity aluminum 1350-0 wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the “0” (fully annealed or soft) temper aluminum. Steel core wires are protected from corrosion by Galfan® , zinc-5% aluminum-mischmetal alloy coating. High strength steel core, aluminized, and aluminum clad steel core is also available.
Characteristics
- This product enjoys many advantages in design including lower power consumption, lower sag, and high corrosion resistance.
- Compared with ACSR/TW, emergency power load causes less sag to this product. ACSS/TW has excellent self-damping properties so that it is not easily droop because of gradual deformation of the aluminum coating.
- It can endure up to 250℃ temperature under the condition of constant working without becoming soft.
- This product conforms to the ASTM B857 standards.
