Overview of the products

XGN □ -12 solid insulation ring main unit switchgear is a new generation of environmentally friendly solid insulation ring main unit independently developed by this Co. and mainly composed of five functional units, namely, V unit (circuit breaker unit), C unit (load switch) and F unit (switch on unit). Each unit can be used independently or expanded freely. Its structure is divided into intelligent control instrument room, operating mechanism and primary part. The instrument room can be equipped with microcomputer protection (controller). The mechanism is a special missile operating mechanism. The primary part uses APG automatic gel process to completely seal the disconnector and chamber in epoxy resin and has a special joint and bus side. The design switch of the arc extinguishing chamber adopts dedicated copper bell contact material, R-type longitudinal magnetic field contact, and complete one-time sealing process. The short-circuit current breaking ability, stability, electrical life, temperature rise, and insulation level of the arc extinguishing chamber have been significantly improved compared to the previous ones(copper aluminum contact material, cup-shaped longitudinal magnetic field contact structure, and incomplete one-time sealing process).
