HXGN17-12 AC metal-enclosed ring main unit (load switch) (hereinafter referred to as RMU) is a new type of high-voltage switchgear produced to meet the needs of urban power grid renovation and construction. It is also used in power supply systems for making and breaking load current and short-circuit current, as well as closing short-circuit current. This RMU is equipped with FZRN25 and FZRN21 vacuum load switches. The operating mechanism is a spring mechanism, which can be operated either manually or electrically. The grounding switch and disconnect blade are equipped with manual operating mechanisms. This RMU features strong assembly integrity, small size, no risk of combustion or explosion, and reliable "five-prevention" functions.
This RMU complies with the relevant provisions of GB3906 "AC Metal-enclosed Switchgear for Rated Voltages of 3.6kV to 40.5kV" and IEC60420 "High-voltage AC Load Switch-Fuse Combination Units".
