Outdoor high-voltage drop type fuses, series (H)RW5-40.5 (hereinafter referred to as FUSES), represent the most widespread short-circuit protection switch for distribution line branch lines and distribution transformers. Fuses apply to short-circuit and overload protection of transmission lines and power transformers in power systems having AC 50Hz and a rated voltage of 35 kV. At times, once conditions permit, one may separate and combine no-load overhead lines, no-load transformers, and small load currents. The fuses are mostly applied in distribution lines and the primary side of distribution transformers for protection as well as equipment switching operations. If installed on the branch of the distribution line, then it is possible that the power outage range may be reduced. The fuse complies with technical standards such as GB/T 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 Fuse.” It is meant for applications where conformity with IEC 60-282-1 is required in addition to technical performance. It also complies with technical standards such as GB/T 15166.2-2008 “High Voltage AC Fuses: Part 2: Current Limiting Fuses”.
