For many years, air insulated switchgear was considered to be the most economical solution for medium-voltage power distribution systems. 150 Views • Jun 19, 2017 • General Product Literature By staying here you are agreeing to our use of cookies. Air Insulated Switchgears (EVA MMMH) are medium voltage switching elements used in the secondary distribution system of electricity at levels of 12 kV, 24 kV, and 36 kV and according to the customer various demands. It plays a controlling and protecting role in the power system. 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 ). By staying here you are agreeing to our use of cookies. In earlier days for any voltage ratings AIS or outdoor substation is employed. Switchgear Assemblies, Breakers, Contactors are designed and manufactured according to IEC 62271 series. A point of note is that the GIS contain the same compartments and components as the normal (AIS) setups. For arc-resistant applications, ABB’s famous SafeGear® line features ratings up to 4000 A, 63 kA at 5 and 15 kV with the smallest footprint available in the industry.
