Structural features The shell of this cabinet is made of steel plate or molded With a closed structure, this equipment has strong completeness, small size, no danger of combustion and explosion, and has reliable five-proof functions. The fuse combination electrical cabinet and the fuse tube have a striker. In the case of a short circuit, the striker hits the tripping mechanism to achieve Quick breaking, can effectively protect electrical equipment.
Performance introduction Due to the compact design structure and small volume, it can be installed in a ring main unit with smaller volume requirements. In a single use solution, the cabinet volume can reach up to The cabinets of wide and deep switch and fuse combination appliances can be wide, deep and high.
In line with the requirements, the cabinet is made of cold-rolled steel plates and formed by a CNC machining center. The assembled cabinet parts are fixed by nuts.
The low-voltage room is separated from the high-voltage room, and the insulation distance between it and the conductor in the high-voltage room is greater than . The protection level is reached.
