HXGN17-12

BOX-TYPE FIXED AC METAL-
ENCLOSED SWITCHGEAR

Overview
HXGN17-12 AC metal ring network switchgear (load switch) (referred to as ring network cabinet) is a new high-voltage switchgear produced for the
transformation and construction of urban power grids. In the power supply system, it is also used as the breaking load current and short-circuit current
and closing short-circuit current. The ring network cabinet is equipped with FZRN25 and FZRN21 vacuum load switches, and the operating mechanism
is a spring mechanism. The mechanism can be operated manually or electric. operating. The grounding switch and the isolating knife are equipped with
a manual operating mechanism. The ring network cabinet is strong in set, small in size, free from burning and explosion hazard, and has a reliable "five-
proof" function.
The 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".
