Products Description
overview
RW12-15 (F) outdoor high voltage AC drop fuse (hereinafter referred to as "fuse") is applicable to the outdoor overhead distribution systems with a rated frequency of 50Hz and rated voltage of 10kV. It is used as a protective element of circuit or electrical equipment in case of overload or short circuit fault of a power system. When traveling normally, the fuse is connected in series in the power line, the fuse is in a tensioned state, and the movable joint is locked. When the line fails, the fault current causes the fuse to blow, the movable joint is released, the fuse tube is quickly dropped, and the circuit is cut off, which plays a role in safety protection for the maintenance of the line and equipment. The load type fuse is added with elastic contact and arc extinguishing cover on the basis of the ordinary type, which is used to open and close the load current in the power system.
The fuse shall comply with technical standards such as GB / T 15166.3 - 2008 high voltage AC fuses - Part 3: injection fuses, DL /T 640 - 1997 outdoor AC high voltage drop tested fuses and fuse links ordering technical conditions.
