产品概述 Product briefaccount

XGN15-12型单元式六氟化硫环网柜是新一代以六氟化硫负荷开关作为主开关而整柜

采用空气绝缘的、适用于配电自动化的、既紧凑又可扩充的金属封闭开关设备。

环网柜适用于三相交流50Hz，额定电压12kV的户内配电装置。广泛应用于工业及民

用电缆环网及供电末端。特别适用于小型二次配电站、开闭所、工矿企业、城市居民小区、

机场、铁路、隧道、高层建筑等电力系统中作为接受和分配电能之用。

XGN15-12 Unit-type SF6 RUM cabinet that whole air-insulated is assembly composed with SF6

loading switch as the main switch suitable for distribution automaticboth compacted and extending

switch.

The ring main unit is suitable for 3-phase AC 50Hzrated current 12kV indoor distribution. It is

widely used as industry and civil cable ring and power supply end pointIt is also especially

suitable for small secondary distribution stationtransformer stationindustry-mine enterprise

civil district,airport,railway,subway,high-storey building.etcused as receiving and distributing power
