 Trapezoidal aluminum conductors steel-supported (ACSS/TW) are used for overhead transmission lines. They are especially useful in reconductoring applications requiring increased current with existing tensions and clearances; new line applications where structures can be economized due to reduced sag; new line applications requiring high emergency loadings; and lines where aeolian vibration is a problem.
Construction
ACSS/TW, a nonhomogeneous conductor, is a trapezoidal shaped wire compact concentric-lay-stranded conductor made from aluminum 1350-O wires and round, coated steel core wire(s). ACSS/TW conductors with equal area or equal diameter as compared to ACSS conductors are available for overhead lines. Steel wires are coated with Class A coating of zinc – 5% aluminum mischmetal alloy. Other Classes of coatings are also available for additional protection from corrosion. Standard, High, Extra and Ultra High Strength steel are also available.

Features and Benefits
1.ACSS/TW conductors are similar to conventional ACSR/TW conductors but have some very important additional advantages. ACSS/TW conductors can operate continuously at high temperatures (up to 250°C) without damage. ACSS sags less than ACSR/TW under emergency electrical loadings, it has self-damping properties, and its final sags are not affected by long-term creep of the aluminum.
2.ACSS/TW conductors constructed of equivalent aluminum circular mil cross-sectional area provide a conductor that is smaller in overall diameter than the equivalent conventional round wire ACSS conductor. The reduced conductor diameter is advantageous in reducing the effects of ice and wind loading on the conductor.
3.ACSS/TW conductors constructed to be equivalent overall diameter enable a greater circular mil cross-sectional area of aluminum within the conductor, reducing power loss in the conductor for day-to-day operations as well as allowing a significant increase in conductor current-carrying capacity.
