1,KYN28 Type switchgears adopt cabinets made of zinc plate with aluminum cladding after multiple bending and bolted connection.

2,Main switches may use VD4, VM1, HD4, VEP, ZN63A, ZN6, ZN63M, and other centrally positioned handcart-type vacuum and sulfur hexafluoride circuit breakers with composite insulation or cementing insulation, whose operating mechanism is spring or permanent magnet. 

3,Or V7 and V12 type handcart -type vacuum contactors may be employed. 

 4,These switchgears are suitable for power plants, substations, industrial and mining enterprises and institutions, and other places of power distribution.
