Description：
Breakthrough innovation is achieved through technology integration. Combining the product development experience of air-insulated switchgear and gas-insulated switchgear, the QGG Series Solid Insulated Switchgear has been developed, which represents a major breakthrough in the field of medium-voltage technology and features high operational safety. As a core unit of the power distribution network, it is applied in power distribution networks. It adopts a vacuum interrupter for arc extinction, and its high-voltage live parts are molded from solid insulating materials with excellent insulating performance (epoxy resin materials), eliminating the air chamber with a pressure of 0.03Mpa and realizing full insulation, full sealing, and maintenance-free operation. The QGG Series Solid Insulated Switchgear is equipped with an intelligent online monitoring system, which monitors the status of key components inside the switchgear in real time, acquires status parameters, automatically evaluates the possibility of faults, and provides strong protection for the normal operation of the switchgear and the entire power distribution line. After years of dedicated R&D, the solid insulated switchgear has formed IV product series, each with its own unique characteristics.
