GTXGN-12 Solid-insulated Switchgear is a new generation of fully-insulated and fully-enclosed environment-friendly switchgear. All live parts are enclosed in epoxy resin housing with APG injection moulding, and the adjacent cabinets are connected by plug-in solid-insulated bus, so the switchgear will not be affected by external environment.
GTXGN-12 Solid-insulated Switchgear includes three cabinets of basic functional units: vacuum load switch cabinet, vacuum load switch & fuse cabinet combination, and vacuum circuit breaker cabinet, which applies to 10kV threephase AC 50Hz single-busbar system. As an equipment to receive and distribute electric energy, it is provided with line control, protection, monitoring and communication, and can be used in airport, subway, large building, secondary substation and mining or industrial enterprises, especially suitable for those occasions with narrow place, poor environment, high altitude and maintenance free requirement.
Quality assurance is established based on continuous improvement in the process of research, development, design and production in compliance with quality system. The manufacturing factory has passed ISO9001 certification.
The product has been provided with type test as required by National High-voltage Test and Inspection Center, whose basic parameters and technical index conform the following standards:
GB 1984-2014 High-voltage alternating-current circuit-breakers
