Main Structure Features:
1.The drop-out fuse consists of an insulating bracket and a fuse tube.
2.Static contacts are mounted at both ends of the insulating bracket, and dynamic contacts are installed at both ends of the fuse tube.
3.The fuse tube comprises an inner arc extinction tube and an outer layer (phenolphthalein paper or epoxy glass cloth).
4.Features include small volume, light weight, simple process, flexible installation, easy operation, and strong outdoor adaptability.
5.It can turn on and off non-load current and, with an arc extinguishing chamber, can handle load current as well.
