Medium-voltage switchgear N2X -12

high-voltagemetal-cladgas-insulated

　　N2X-12 non-SF6 gas-insulated metal-enclosed switchgear, designed and developed by the German senior experts, is a new generation of Medium-voltage C-GIS product integrating the excellent advantages of gas insulation and vacuum breaking technology, and the company owns all the intellectual property rights. 　　* Using micro positive pressure (rel.0.02MPa) and environmental-friendly N2 as insulating gas to reduce the negative influence to the environment and the risk of gas leakage. 　　* Less space occupation. Each panel can save land by 40% ~ 73%. 　　* Modular gas tank structure, Suitable configuration schemes can be chosen based on the exact requirements to ensure the reliable and economic operation of switchgears. 　　* Maintenance free on primary circuit. All the high-voltage circuit are gas sealed and not influenced by the environment. 　　* Using VEG vacuum circuit breaker , with mechanical endurance up to 10,000 operations, so as to increase the performance and reliability of the equipment. The special vacuum interrupter design makes non-restrike possible for 12kV 630A capacitor bank switching. 　　* High-voltage gas tank is manufactured by 3D 5-Axis laser welding of 3mm stainless steel sheet, and checked by helium leakage detection machine. Ensure annual leakage rate less than 0.1%
