10KV–15KV Drop Out Fuse (Drop Type Fuse for Overhead Power Lines) is a medium-voltage protection device widely used in overhead distribution networks to safeguard transformers, feeders, and electrical equipment from overload and short-circuit faults. It operates with a simple yet reliable mechanism: under normal conditions, current flows through the fuse link continuously, but when abnormal current occurs due to lightning strikes, system overload, or short circuit, the fuse element melts rapidly, releasing the fuse tube to drop downward and create a visible air gap for safe circuit isolation. This design not only ensures fast fault interruption but also provides clear visual indication for maintenance personnel, improving operational safety and efficiency in field environments. The product is typically rated for 10KV–15KV systems and is suitable for rural power grids, industrial distribution lines, and pole-mounted transformer protection. Manufactured with high-strength porcelain or composite insulation, anti-aging materials, and precision metal contacts, it delivers excellent mechanical strength, electrical stability, and weather resistance under harsh outdoor conditions such as humidity, dust, and temperature variation. Advanced production processes include high-temperature forming of insulation parts, anti-corrosion treatment of conductive components, and strict assembly control to ensure consistent performance and long service life. Each unit undergoes rigorous testing including dielectric strength verification, thermal cycling, and mechanical drop operation tests to guarantee reliability in real-world applications. With stable performance and easy installation, the 10KV–15KV drop out fuse is an essential protective component for modern overhead power systems, ensuring continuous and safe electricity distribution.
