Air insulated switchgear (AIS) is an auxiliary distribution unit used to disperse the electrical energy of the main transmission unit fed by a large distribution transformer. adopts the air as the insulation media designed voltage ranging from 11KV to 36KV medium voltage power distribution system. It plays a controlling and protecting role in the power system.
The air insulated switchgear is a secondary power distribution device and is a medium voltage switchgear that redistributes the power of a primary power distribution device that is powered by a high voltage distribution transformer.
It is widely used in power distribution stations and compact substations in load centers such as residential areas, high-rise buildings, large public buildings, and factory enterprises.
