Summary
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 operatingrequirements in public and industrial medium-voltagedistribution systems. This panel applies to 3.6~12kv 3 phaseAC 50Hz / 60Hz network for receiving and distributing powerenergy and also for control, monitor and protection. It canbe arranged for single bus, single-bus sectionalizing systemIt accords to IEC62271-200 <<AC Metal Enclosed Switchgealand Control Equipment above 1kv and below 52kv>>
IEC694<<Standard Common Clause for HV Switchgear andControl Equipment>>,GB3906<<3~35KV AC Metal EnclosecSwitchgear>>, DL404<<Order Specification for Indoor AC HvSwitchgear>>, DIN.VDE0670<<AC Switchgear at Rated Voltageover 1kV>> and so on. It has perfect and reliable prevention function against false-operation.
