ACSS Trapezoidal Wires ASTM sizes
SYSTEM RELIABILITY & FLEXIBILITY: ACSS conductors allow Utilities to operate their lines at normal day to day electrical loads, while enabling severe contingency/emergency ratings. ACSS permits important increments of ampacity when compared with similar in size conventional conductors (ACSR / AAAC) by operating at high temperatures up to 250 ºC, without any risk of thermal degradation. Several alternatives are available. Compact designs constructed of fully annealed trapezoidal wires (equivalents in area or in diameter) or designs with round wires. Unlike ACSR, the mechanical responsibility and sag and tension performance of ACSS conductors lies mainly on the steel core.
