High Voltage Porcelain Drop-Out Fuse

The outdoor drop-out fuse is used to protect power distribution lines and transformers from overload and short-circuit damage, and is used for disconnecting equipment in 10kV to 38kV AC systems. Its design takes into account the most common operating conditions and applications, and has the following excellent features: 1. Equipped with arc-extinguishing (extension) rods according to the fuse specifications to enhance the breaking capacity. 2. Advanced fuse tube design. 3. Reliable and efficient electrical path. 4. All metal components are treated with special processes to prevent corrosion and rust. All technical performances comply with GB/15166.3, IEC60282-2 and ANSI/IEEE37.41 standards.
