(H) RW5-40.5 series outdoor high voltage drop type breaker (hereinafter referred to as cauterizer), is the most common short-circuit protection switch for distribution line branch lines and distribution transformers. The fuse is suitable for the power system with AC 50H2 and rated voltage of 35kV as the short-circuit and over-load protection of transmission lines and power transformers. Under certain conditions, no-load overhead line, no-load transformer and small load current can be divided. Fuses are widely used in the primary side of distribution lines and transformers for protection and equipment switching operation. It is installed on the distribution line branch to reduce the power outage range. Fuses comply with GB/T 15166.3-2008 "High voltage AC Fuses Part 3: Jet fuses", DL/T 640-1997 "Outdoor AC high voltage drop fuses and fuse parts ordering technical conditions" and other technical standards. Fuses comply with GB/T 15166.2-2008 "High voltage AC Fuses Part 2: Current limiting fuses" and other technical standards.
