CONSTRUCTION: ACSS/TW is a composite concentric-lay-stranded conductor. Steel strands fonn
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

Aluminum Conductor, Steel Supported.
Trapezoidal Shaped Aluminum Strands. Bare.
APPLICATIONS
Southwire's ACSSITW 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
ACSRITW,
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
