Drop-out fuse cutout is of outdoor used AC HV protective device. To be connected with in-feeder of distribution transformer of distribution lines, it mainly protect transformer or lines caused by short-circuit and overload, and on/off loading, current. The drop-out fuse cutout is composed of insulators and fuse tube, static contactor is fixed on two ends of the insulator holder while the moving contactor is mounted on two ends of the fuse tube. The fuse tube is composed of epoxy glass tube.
