This series is puffer interrupting pad mounted fully deadfront switchgear for underground system up to 25.8kV, 600A, enclosed in stainless steel tank full of SF6 gas insulation media.
It incorporates grounding switches in every way to provide added safety and faster working.
Features:Insulation, break, and simple grounding by SF6
-
This series is 3 phase, SF6 gas insulated load break switch (LBS) for overhead lines operating at a voltage up to 38kV.
It meets the demand for oil-less and maintenance free operation with SF6 gas, related parts and devices installed inside its hermetically sealed stainless steel tank.
It can be manually operated or motorized for sectionalizing,
-
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
