Switchgear - Wikipedia 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 the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.[email protected]

Effects of MV and HV cable capacitance on operational ... transmission does not suffer from the same problems as AC. DC transmission has its own additional costs, primarily converter stations. The insulation requirements for DC cables are lower than for AC and hence costs are lower. HVDC transmission systems are normally associated with overhead lines but cable-based systems have been developed.
