GENERAL
Switchgear RM6-40.5 includes a series of expandable SF6-insulated metal-clad switchgears at the voltage rating of 40.5kV.All live parts of primary high-voltage circuit are wholly enclosed in a welded cabinet of 3mm-thickness stainless steel sheets, which gives a small volume. The switchgear is not subject to the influence of surrounding conditions so that it guarantees the safe and reliable running and zeromaintenance. It can be integrated as module by using plug-in expansion busbar. Meet requirements of end users or network nodes and satisfy demands of various substations and switching stations, box-type substations, cable branch boxes and wind turbine towers. It features the compact structure, safety, reliability, long life and zero maintenance.
RM6 series provides transformers with following protections:
*Load switch-fuse composite apparatus.
*Vacuum breaker with relay protection.
