  • Hybrid Insulated Switch Gear

    Switchgear may be a simple open air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is “gas insulated switchgear” (GIS), where the conductors and contacts are insulated by pressurized SF6 (sulfur hexafluoride). Other common types are oil or vacuum insulated switchgear.
