(H)RW12-12(F) outdoor high-voltage AC drop type fuses (hereinafter referred to as “this fuse”) are applicable to outdoor hanging distribution systems with a frequency of 50Hz and rated voltages of 10kV. It gets installed as a protective element for circuits or electrical equipment in any case the power system faces an overload or short-circuit fault. When normally operating as the fuses, it connects in series within the power line. Ine, with the fuse in a taut state and the movable joint locked. When a fault occurs in the circuit, the fault current causes the fuse to melt, the movable joint is released, and the fuse tube quickly drops, cutting off the circuit and providing safety protection for the maintenance of the circuit and equipment. Load-type fuses add elastic contacts and arc-extinguishing covers on the basis of ordinary types, used for breaking and closing load currents in power systems. The fuse complies with technical standards like GBT 15166.3-2008 “High voltage AC Fuses Part 3:Jet Fuses” and DLT 640-1997 “Technical Conditions for Ordering Outdoor AC High Voltage Drop-type Fuses and Fuses”.

What is a Fuse Cutout? A fuse is an electronic device used to protect electrical circuits. When the current exceeds a specified value, the fuse breaks the circuit by fusing the melt through the heat it generates. 2. What voltage range does this Fuse Cutout support? The HRW12-12F Fuse Cut is for installation on the high-voltage side of the distribution transformer or distribution line branch line,Not exceeding 36 kV used as overload and short-circuit protection of the transformer and line, and to divide and close the rated load current. 3. How does the drop-out mechanism work? Falling fuse to make the fault current quickly fuse, through the arc in the tube heating, decomposition of gas, the formation of pressure, will be quenched in the tube, after the formation of open, the arc will be extinguished. 4. What materials are used in the construction of the Fuse Cutout? Divided into ceramic and composite materials, it consists of two parts: the insulating support and the fuse tube. 5. How easy is it to maintain the Fuse Cutout? Easy and simple to use, with durable materials that reduce the number of breakdowns and increase efficiency. 6. Can the Fuse Cutout be used in industrial applications? Can be used in various large facilities, substation transformers, power stations, new energy sources and other places to provide stable protection.
