Overview

HXGN17-12 AC metal ring network switchgear (vacuum load switch) (referred to as ring network cabinet) is a new type of high-voltage switchgear produced for the needs of urban power grid transformation and construction. In the power supply system, it is also used for breaking load current, short-circuit current and closing short-circuit current. This ring network cabinet is equipped with FZRN25. FZRN21 vacuum load switch. The operating mechanism is a spring mechanism. This mechanism can be operated manually or electrically. operating. Grounding switch and isolating knife are equipped with manual operating mechanism. The ring main unit has strong complete set, small size, no burning and explosion hazard, and reliable “five prevention” functions.
This ring main unit complies with the relevant regulations of GB3906 «3-35kV AC Metal-enclosed Switchgear” and IEC60420 “High Voltage AC Load Switch Fuse Combination Electrical Appliances” standards.
