Product Q&A

Q:What is GTXGN-12 Indoor Fixed Solid Insulated Ring Main Unit?

GTXGN-12 is indoor fixed SF6-free solid insulated RMU. All high-voltage live parts are encapsulated in epoxy resin shell with vacuum interrupter inside. Features full-insulation, full-shielding, maintenance-free for indoor 12kV distribution network.

Q:What are main rated technical parameters?

Rated voltage 12kV, 50/60Hz; rated current 630A-250A;short-time withstand current 20-25kA/3s; cabinet protection grade IP4X.

Q:Does this RMU use SF6 gas for insulation?

No SF6 gas applied. It adopts epoxy resin solid insulation + vacuum interrupter. Zero greenhousegas emission, no risk of gas leakage or low-temperature liquefaction, fit for plateau and cold-area projects

Q:What functional units are available?

Support load-switch C-unit, fuse-combination F-unit, vacuum breaker V-unit. Feeder quantity can be customized according to customer project.

Q:Is isolation fracture visible for maintenance?

Yes. Equipped with visual isolation fracture observation window, operator can clearly judge disconnector status during maintenance work for safety operation.
