Drop-out fuse and pull the load drop-out fuse is outdoor high-voltage protection of electrical. It is installed in high-voltage side of the distribution transformer or the Support Link of the distribution line as Transformers and lines short circuit, overload protection, and open, co-load current. Drop-out fuse is made by the insulating bracket and fuse tubes, static contact is installed at both ends of the insulation bracket, Moving contact installed on both ends of fuse tube, Fuse tube is composed by inner arc tube and outer phenolic paper tube or epoxy glass cloth tube. Pull load drop-out fuse can enhance flexibility auxiliary contacts and arc chute for open, co-load current.
