Bare Aluminium Transmission and Distribution Cable

ACSS/TW

Aluminum Conductor, Steel Supported. 
Trapezoidal Shaped Aluminum Strands.  Bare.

APPLICATIONS

Southwire's ACSS/TW is designed 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 under emergency electrical loadings than
ACSR/TW, excellent self-damping properties, and its final sags are not affected by long-term creep of aluminum.
Southwire's ACSS/TW is available in equal area and equal diameter design. The equal area design allows equal ampacity
in a smaller diameter conductor when compared with a standard ACSS conductor. The equal diameter design allows
more ampacity in an equal diameter conductor when compared with a standard ACSS conductor. ACSS/TW also
provides many design opportunities for new line construction: i.e., reduced tower cost, decreased sag, increased self-
damping properties, increased operating temperature and improved corrosion resistance.

SPECIFICATIONS

Southwire's 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 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.
