China Customized 33kv High Voltage Switchgear ... High Voltage Switchgear. Overview: The switchgear is suitable for power plants, substations, combined substations and power systems. The system is a three-phase indoor AC single bus and segmented single bus, with a rated voltage of 50Hz, 35kV, used to control, receive and distribute power.
Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
New SF6 Gas Detection Capability - AWE International· Insulating gas for high voltage switch gears, circuit breakers, and electrical equipment. This is because, under pressure, SF 6 has a much higher dielectric strength than air or nitrogen. This means that gas-insulated switchgears can be placed indoors and can be significantly smaller in size compared to air-insulated switchgears.
