ACSS Aluminum Conductor Steel Supported by Nassau National Cable

ACSS, designed for overhead power transmission and distribution, operates continuously at high temperatures up to 250°C without strength loss. It sags less than comparable ACSR under electrical loadings, is self-damping when prestretched, and its final sags aren't affected by long-term aluminum creep. These advantages make ACSS ideal for reconductoring projects needing increased current, new lines where structures can be economized due to reduced sag, high emergency loading applications, and lines prone to aeolian vibration.
