Drop-out fuse

Drop-out fuse is the core protection device for 10kV/35kV outdoor power distribution systems, widely installed on overhead lines and high-voltage sides of distribution transformers to provide short-circuit and overload protection. When a fault occurs, the fuse element melts rapidly, and the fuse tube drops automatically to form a visible break point, realizing safe isolation and fault indication. Featuring high-strength insulation structure, it offers fast arc extinction, reliable operation, and easy installation & maintenance, adapting to harsh outdoor environments and serving as a key component for safe and stable distribution grid operation.
