Technical FAQs 4

What is LV switchgear?

LV (Low voltage) switchgear is an engineered solution used to control, protect, and isolate electrical equipment or systems to allow work to be done and clear faults quickly and safely when required.

What is air insulated switchgear?

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.

What is low voltage switchgear?

Low voltage switchgear is rated up to 1KV and consists of low voltage switches, earth leakage circuit breakers, HRC fuses, electrical isolators, Air circuit breakers (ACB), Molded case circuit breakers (MCCB) and miniature circuit breakers (MCB).

What type of switchgear is used to isolate a transformer?

This type of switchgear is used for medium-voltage power distribution, from 7.2kV to about 36kV volts. Ring main units can be characterized by their type of insulation: air, oil or gas. The switch used to isolate the transformer can be a fusible switch, or maybe a circuit breaker using vacuum or gas-insulated interrupters.
