Abstract

An electric power fuse without an additional fuse holder is provided to reduce costs for manufacture and installation by integrating the holder in one body without installing an additional fuse holder on an insulator. An electric power fuse without an additional fuse holder includes insulator fuse fixing frames(10,10a), an insulator(20), elastic insulator supporting frames, and lift stretching frames. The insulator fuse fixing frames fix an insulator on the left and support a fuse body to expand and contract on the right. The insulator is fixed on the insulator fuse fixing frames. The elastic insulator supporting frames elastically support the insulator from the left. The lift stretching frames stretch the fuse body up and down and couple and separate the insulator.
