Overview

SAS 400 series is 3 phases, SF6 gas insulated auto section switch (ASS) for overhead lines operating at a voltage up to 25.8kV. It is designed for a self-contained, circuit-opening device used in conjunction with source-side protective devices such as auto reclosers or circuit breakers, to automatically isolate the faulty section caused for the fault current or overload current on power distribution systems.
 The switch meets the demand for oil-less and maintenance free operation with SF6 gas, related parts & devices installed inside its hermetically sealed stainless steel tank.
