KYN28-24 Withdrawable Metal-clad Switchgear

Product Introduction

SUMMARY

KYN28A-24 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 13.8～24kv 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.
