GTXGN-12 Solid insulated Ring Main Unit Switchgear is a new generation environmentally friendly composite insulated ring mainunit switchgear independently developed by our company.lt is a fully sealed power supply unit, with all live parts and switches fullysealed in an epoxy resin housing, without SF6 gas inside the housing. The entire switch device is not affected by externalenvironmental factors, ensuring operational reliability, personal safety, and achieving maintenance-free operation. GTXGN -12Solid insulated Ring Main Unit consists of three units: V unit (circuit breaker unit), C unit (load switch unit), and F unit (combinedelectrical unit), Each unit can be used individually or expanded freely, lts structure is divided into intelligent control instrument roomoperating mechanism, and primary part. The instrument room can be equipped with a microcomputer protection (controller, andthe primary part uses APG automatic gel technology to completely seal the isolation switch and arc-extinguishing chamber in epoxwresin, with dedicated connectors connected to the busbars. The arc-extinguishing chamber uses special copper-chromium contacimaterials, R-type longitudinal magnetic field contacts, and a fully sealed and cast process.The breaking short-circuit current capability, stablity, electrical life, temperature rise, and insulation level of this arc-extinguishingchamber have significantly improved compared to the previous arcextinguishing chamber (copper-aluminum contact materialscup-shaped lonaitudinal magnetic field contact structure, and incomplete sealing and casting process. The operating mechanismuses an integral spring operating mechanism that coordinates with the switch, where the isolating switch and main switch springoperating mechanism are integrated, making it easy to achieve interiocking. The mechanism has fewer parts, reducing unnecessarytransmission links, resulting in high reliability, and can be electrically operated according to user needsGTXGN二-12 Solid insulated Ring Main Unit: lt uses solid insulating materials as the main insulating medium and solid insulatingmaterial for main conductive connections, isolating switches, grounding switches, main busbars, branch busbars, etc, andencapsulates them into one or several modules with certain functions, which can be combined or expanded again, possessing full
insulation and sealing performanceGTXGN_-12 Solid insulated Ring Main Unit is suitable for 12ky, 50Hz three-phase AC distribution systems, used for ring networkbower supply or terminal power supply, The ring network unit can be installed in distribution systems of industrial and mininaenterprises, residential communities, schools, parks, etc, it can also be installed in compact prefabricated substations for the controand protection of distribution transformers, Therefore, both indoor and outdoor ring network units can achieve power distributionautomation.
