(H)RW12-12(F) outdoor high voltage AC drop fuse (hereinafter referred to as "fuse"), suitable for outdoor overhead power distribution system with rated frequency 50Hz and rated voltage 10kV, as overload or short circuit fault of power system Protective element of a circuit or electrical device. When the fuse is in normal operation, it is connected in series in the power line, the fuse is in tension, 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 is quickly dropped, the circuit is cut off, and the protection of the line and equipment is safe. The load type fuse adds a spring contact and an arc extinguishing cover on the basis of the common type, and is used for dividing the load current in the power system. The fuse meets the technical standards of GB/T 15166.3-2008 "High Voltage AC Fuse Part 3: Jet Fuse", DL/T 640-1997 "Outdoor AC High Voltage Drop Fuse and Fuse Parts Ordering Technical Conditions".
