Provides Middle Rolling and Floor Roiling two different withdrawble types, can meet all our customers' technical requirements and operating features.
Reliable "anti-5" mechanical latch, convenient and safe maintenance,
Both VCB of ZN85-40.5/VS1-40.5 developed by our company and VD4, VB2 AND 3AH manufactured by other companies around the world can be matched with the switchgear.
KYN61-40.5 Series switchgear panel is a MV air-insulated switchgear (AIS) for primary distribution, with vacuum circuit-breaker has been designed for the various operating requirements in public and industrial medium-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 <>, IEC694<>, GB3906<<3～35KV AC Metal Enclosed Switchgear>>, DL404<>, DIN.VDE0670<> and so on. It has perfect and reliable prevention function against false-operation.
