。[Claims for Utility Model Registration] (1) A fuse element is connected between the head terminal and the lower lead wire, and the fuse element is placed inside an arc extinguishing tube and covered entirely with a kraft or polycarbonate covering tube, and the open end of the covering tube is In a high-pressure cut-out fuse that has a stopper nearby to prevent lead wires from sagging, the arc-extinguishing cylinder has a content of 60 to 90% by weight.
It consists of a cylinder made of non-combustible paper, in which aluminum hydroxide is held in cellulose fibers, and a lining of boric acid applied to the inner surface of this cylinder. A high-pressure cut-out fuse characterized by having a length that allows the section to be pulled out from the end of the arc-extinguishing tube. (2) The stopper for preventing the lead wire from hanging is composed of a fluorine resin tube and an adhesive ring fitted around the outer periphery of this tube. 2. The high-pressure cutout fuse according to claim 1, wherein the fuse is adhesively fixed near the opening end of the covering tube.
