Overview
XGN66A-12 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 3.6 ~ 12kV 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.
