12KV RMU SF6 Load Switch Gas Insulated Switchgear HXGN15
SF6 RMU HXGN15 Load Switch Module 12KV GIS GB ISO IEC
Product Introduction
General
The load switch for the power supply cabinet is generally called C module, which is generally used in high-voltage three-phase five-wire cabinets.
Load switch unit which called C-unit included bus-bar, three-station load/earth switch, three-station single spring operating mechanism, there are two independent load switch and ground, switch operation hole, load switch and earthing switch position indication, indicates the kiln voltage indicator of the casing, etc.
