KYN61-40.5 withdrawable metal-clad switchgear

Overview

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.
