The 40.5kV Polymer Drop-out Fuse Cutout is a high-voltage protective device used for outdoor power systems. It provides reliable overcurrent and short-circuit protection for substations, distribution lines, and pole-mounted transformers. This fuse cutout adopts high-grade HTV silicone rubber for insulation, offering lightweight construction, excellent weather resistance, and strong anti-pollution capability.
When a fault occurs, the fuse link melts instantly and the fuse tube drops, disconnecting the circuit to protect the electrical system.
