(ACSS/TW) Steel Recinforced Trapezoidal Shaped Soft Aluminum Conductors 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.
Various types of steel wire & T-Shaped Aluminum 1350-O wires.
