RW5 Drop Out Fuse,
XG Drop Out Fuse,
31.5kv Drop Out Fuse
The drop fuse is an outdoor high voltage protector that pulls the load drop fuse. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line, and is used as a short circuit, overload protection and load and load current of the transformer and the line. The drop fuse is composed of an insulating bracket and a fuse tube, and the static contact is installed at two ends of the insulating bracket. The moving contact is installed at both ends of the fuse tube. The wire tube is composed of a layer arc extinguishing tube and an outer layer of epoxy glass tube. The pull-down type fuse adds a flexible auxiliary contact and an arc-extinguishing cover for dividing and combining the load current.
