- Commodity name: HXGN17-12 AC Metal-Enclosed Ring Network Switchgear (Vacuum Switch)
The HXGN17-12 AC metal-enclosed ring network switchgear (vacuum switch) (referred to as ring network cabinet) is a new type of high-voltage switchgear produced to meet the needs of urban power grid renovation and construction.
HXGN17-12 AC Metal Ring Network Switchgear (Vacuum 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. It is also used in the power supply system to break load current and short-circuit current, as well as to close short-circuit current. This ring network cabinet is equipped with FZRN25 and FZRN21 vacuum load switches, and the operating mechanism is a spring mechanism, which can be operated manually or electrically. The grounding switch and isolating knife are equipped with manual operating mechanisms. This ring network cabinet has strong completeness, small size, no burning and explosion hazards, and also has reliable "five prevention" functions. This ring network cabinet complies with the relevant provisions of GB3906 "3-35kV AC Metal Enclosed Switchgear" and IEC60420 "High Voltage AC Load Switch Fuse Combination Electrical Equipment" standards.
