KYN61 Series 40.5kV MV Withdrawable Metal-Clad Switchgear
SUMMARY
KYN61-40.5 Series switchgear panel is a MV air-insulated switchgear (AlS)for primary distribution,with vacuum circuit- breaker has been designed for the various operatingrequirements in public and industrialmedium-voltage distribution systems.
This panel applies to 27~40.5kv 3 phase AC 50Hz/60Hz network for receiving and distributing power energy and also for control,
monitor and protection.
It can be arranged for single bus,single-bus sectionalizing system.It accords to IEC62271-200 <<AC Metal Enclosed Switchgear and Control Equipment above 1kv and below 52kv>>,IEC694<<Standard Common Clause for HV Switchgear and Control Equipment>>,GB3906<<3~35KV AC Metal Enclosed Switchgear>>,DL404<<Order Specification for Indoor AC HV Switchgear>>,DIN.VDE0670<<AC Switchgear at Rated Voltage over 1kV>>and so on.It has perfect and reliable prevention function against false-operation.
