Product Description

 

(H) RW10-40.5 (F) This outdoor high voltage AC drop fuse, hereafter simply referred to as the 'fuse,' is expertly designed for outdoor overhead distribution systems operating at a rated frequency of 50Hz and a rated voltage of 10kV. This indispensable protective element ensures unparalleled safety for circuits or electrical equipment during overload or short circuit conditions in power systems. During standard operation, the fuse is strategically connected in series within the power line, maintaining a tensioned state with a locked movable joint. In the event of a line failure, the fault current efficiently causes the fuse to blow, releasing the movable joint, promptly dropping the fuse tube, and interrupting the circuit. This action provides crucial safety protection, facilitating the maintenance of both line and equipment. The advanced load type fuse is enhanced with an elastic contact and arc extinguishing cover, specifically engineered to adeptly open and close the load current in power systems.

This fuse impeccably adheres to technical standards such as GB / T 15166.3 - 2008, which pertains to high voltage AC fuses - Part 3: injection fuses, and DL / T 640 - 1997, which delineates the technical conditions for ordering and testing outdoor AC high voltage drop fuses and fuse links.
