HXGN17-12 Cubicle Fixed Type Alternating-current Metal-enclosed Switchgear (hereinafter referred to as ring main unit) is a new type high-voltage switchgear designed for the transformation and construction of urban power grid. It also can be used for breaking load current or short-circuit current and making short-circuit current in power systems. It is equipped with FZRN25 and FZRN21 vacuum load switch, adopts spring operating mechanism, which can be operated by manual or by electric. The earthing switch and disconnector are equipped with manual operating mechanism. This ring main unit is
of complete set, small size, no flaming or explosive danger, with reliable"five preventions".
It complies with the standards GB3906 A.C. metal-enclosed switchgear for rated voltages of 3~35kV, IEC60420 High-voltage alternating current switch-fuse combinations
