Description

KYN61-40.5 series 33kv power switchgear uses removable vacuum circuit breakers and uses composite insulation to meet the "five-prevention" interlocking function. It is a power distribution device with superior performance. It is used in power plants, small and medium-sized generators, power distribution in industrial and mining enterprises and public institutions, and power reception and distribution in power system substations, as well as large high-voltage motor starting.

KYN61-40.5 removable AC metal-clad switchgear applies to 40.5kV, 3 phase, AC and 50/60Hz electrical power network for receiving and distributing power energy and also for control, monitor and protect ion. It is applicable in general power system and occasions with frequent operation. The product conforms to GB3906: 3~35kV AC Metal Enclosed Switchgear, IEC60694 & GB/T11022: The common technical clauses of HV Switchgear and controlgear Standard, DL/T404-1997: Order Technical term of Indoor AC HV Switchgear and IEC62271-200 1~52kV AC Metal Enclosed Switchgear and controlgear standard.

KYN61-40.5 switchgear is three phase AC 50 Hz,rated voltage of 40.5 KV indoor power distribution equipment.As power plants ,substations and industrial distruction of electric energy only ,and has a circuit implementation of control,protection and monitoring function .
