Product features of Solid Insulated Ring Main Unit Rmu Electrical Switchgear

The KXAIS-12 series Solid Insulated Ring Main Unit Rmu Electrical Switchgear is a fully insulated, fully sealed, and anti condensation ring main unit equipment that is based on solid sealing and vacuum insulation technology, and is independently developed using epoxy resin (APG process) to pour the three position switch (isolation, grounding), circuit breaker vacuum arc extinguishing chamber, and main circuit primary conductive components together to form the insulation component body. It is assembled from insulated busbars and other insulation connectors to form a fully insulated, fully sealed, and anti condensation ring main unit.

By using a circuit breaker vacuum arc extinguishing chamber and independently designing the electrical circuit connection and external structure of the insulation body, the structure of the insulation body is more reasonable in mechanical and electrical aspects. Conductive or semi conductive shielding technology is adopted on the surface of the insulation body to eliminate surface and partial discharge phenomena, truly achieving full insulation.Through independent research and development, we have designed insulated pull rods, transmission devices, and reliable interlocking operating mechanisms that meet the vacuum arc extinguishing requirements of circuit breakers.

By using rubber molding technology, the insulated pull rod and the fixed sealing unit pole are connected with insulated rubber to achieve full sealing, with a protection level of IP67.
