Product discription
Drop-out fuse cutout and load switching fuse cutout are outdoor high voltage protective device.To be connect incoming feeder of distribution transformer or distribution lines ,it mainly protects transformer or lines from short circuit and overload,and on/off loading current,Drop-out fuse cutout is composed of insulator supports and fuse tube,static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube is composed of inside arc extinguishing tube,outer phenolic compound paper tube or epoxy glass tube load switching fuse cutout provides enforced plastic auxiliary contacts and arc extinguishing enclosure for switching on/off loading current.
fuse cutout characteristics
1. Widely applicable for12KV electric distribution as protector;
2. can protect transformer, capacitor, cable, branch cable;
3. polymer fuse cutout can supply reliable overload protection and short circuit protection on right time;
4. fuse cutout can be installed arcing chamber.
high voltage fuse cutout performance
