72.5-245kV plug-in type gas insulated metal enclosed switch gear & control gear

PASS (Plug and Switch System), or the plug-in type gas insulated metal enclosed switch gear and control gear, is the latest combined electrical apparatus developed by ABB company. With breaker, dis-connector and earthing switch placed in a sealed module, the combined electrical apparatus adopts SF6 gas insulation and self-energizing blown arc technology and creatively introduces the advanced modularization and integration design concept, making itself compacted, environmental-friendly and intelligent. PASS is a device used in the outdoor 66-220kV/50Hz power grid to cut off rated working current or fault current, or switch power lines, so as to control, survey, protect, isolated and switch the electric transmission line.
