HXGS?Solid Insulated Electrical Switchgear, 12KV, 24KV,
HXGS?Solid Insulated Electrical Switchgear?is developed on based of its superior patented technologies such as solid insulation, solid sealed pole, fully-insulated modular busbar, etc, solid insulated ring network cabinet fully meet the ring network and radiation distribution network of various wiring programs.
The intelligent terminal equipment connected to the solid insulated switch unit can monitor and control the real-time situation remotely and ensure intelligent, reliability and flexibility of the distribution network system.
??No SF6?gas inside, avoiding pressure tank designing.
??All live parts are sealed or embedded in the epoxy resin and silicon rubber, fully insulated and wholly enclosed structure, safety protection level: IP67.
??All operating mechanism sealed inside a box, truly maintenance-free.
??Enhanced phase separation design, independent phase insulation to avoid the fault between phases.
??Standard modular design to facilitate unit extension, modification and replacement.
??Switch working position of each phase could be observed independently.
??Safe, smart, environment-friendly, flexible assembly enabled, good performance to apply in special environments.
??Multiple mechanical interlock to achieve 'five-protection' function.
??Complete indoor & outdoor application solution.
