Summary:
SRK-12 series main switch assembly, already applied in the new generation compact solid RMU,is a complete insulated . and sealed solid dielectric vacuum switchingequipment free of SF6 and maintenance. All the high voltage parts are embedded into epoxy resin with outstanding insulation performance, and the vacuum interrupter, main circuit, etC., are organically integrated with epoxy resin into a complete unit as well.
Different cubicles are also connected by the completely insulated solid dielectric busbar. Therefore, environmental influence has been sharply reduced, which guarantees the system reliability and safety during operation.
This product can be used for the ring network or terminal power supply in the 12kV, 50Hz distribution network, especially suitable for places of small space, unfavorable environment and free of maintenance, such as metro, chemical & oil industry, commercial
buildings, etC, This product can also be used for outdoor Y BM, box-type substation, capable of realizing automatic power distribution after adding protection device, communication module and back-up power.
