1. Produktuen ikuspegi orokorra Produktuen ikuspegi orokorra
Outdoor Dropout Fuse is a key protection equipment in medium-voltage distribution networks, mainly used to isolate fault sections and protect power equipment when short-circuit or overload faults occur in distribution lines. It adopts a mechanical dropout structure: when the fault current passes through the fuse element, the fuse melts quickly, and the moving contact falls under the action of gravity to realize circuit breaking and arc extinguishing. The product’s insulating shell is made of high-strength FRP material, with excellent insulation performance and mechanical strength; the conductive part is made of high-purity aluminum alloy, with good electrical conductivity and low contact resistance. It supports pole-mounted installation on overhead line poles, with simple installation steps and no need for complex civil engineering. The product is available in voltage levels of 10kV and 35kV, and current ratings of 5A-200A, which can meet the protection needs of different specifications of distribution networks, and is an essential equipment for ensuring the safe and stable operation of outdoor distribution lines.
