Drop-out fuse product introduction

Drop-out fuse cutout and load switching fuse cutout are of outdoor


used high voltage protective device.To be connected with incoming feeder of distrbution transformer or distrbution overload, and on/off loading current.Drop-out fuse cutout is composed of insualt insulator suppors and fuse tube, static contact is installed on two ends of fuse tube, static contacts is fixd on two sides of insulator support and moving contact is installed on two ends of fuse tube, outer auxiliary contacts and arc-extinguihing encloure for switching on/off loading current.

At normally working via fuselink tightened the fuse tuble is fixed to form up of close position.In case system occur fault current result in fuselink melt moving contact has no tightened strength again, mechanism is locking, operator shall via insulating cperating bar pulling the auxiliary contact is separated between auxiliary contacts there occur electirc arc will be lengthened in arc-extiguishing enclosure gap and meanwhile arc-extinguishing explode gas to blow off the arc during current passing zero.

High-Voltage fuse series

Cutout features:

The dropout fuse is mainly used to protect lines and transformers against short circuits and overload. Rated voltage: 12KV~36KV; Rated current: 100A, 200A.

1. Interrupting current capability: interrupt current 12.5KA; maximum 16kA fault current/four times.

2. Long creepage distance

3. Fuse tube is composed of Epoxy fiberglass tube and bone fiber. Moisture resistances, high interruption capability, deform resistance, UV resistance, and aging resistance.

4. Material of Contacts consists of copper and copper alloy, and surface is silvered to reduce the resistance, improve conductivity, and lower temperature rise.

5. The lower pocket and contacts are made of copper alloy casting and heat galvanized to achieve high strength, and high resistance to corrosion, and can withstand thermo and dynamic impulse caused by short-circuit current.

6. The upper and lower contacts have good alinement property. No aliening adjustment needed during installation, and easy for operation.

7. Heat galvanized metal parts, high pollution resistance, and 1000h salt-fog pollution test passed.

8. Advanced design to assure fuse tube being hooked after dropout for safety consideration.

9. Interruption using stepwise structure; can interrupt high and low fault current credibility.

10. Water resistance: pressure-relief cap of upper contact has water resistance and can reduce ionized gas to affect the upper circuit. Button of fuse link can promise inside of tube dry.

11. Manufacturing process has high precision; interchangeability

12. Light weight, small volume, convenient to install
