sf6 gas insulated switchgear MultiAnalyser for Ultra High Voltage

A gas-insulated switchgear uses the dielectric gas sulfur hexafluoride, also known as SF6, at moderate pressure for phase-to-phase and phase-to-ground insulation. High-voltage conductors, interrupters, circuit breakers, switches, voltage transformers, and current transformers are in SF6 inside a metal enclosure.
