Product Description High - Performance Outdoor High-Voltage AC Drop Fuse for 12kV Power SystemsOur outdoor high - voltage AC drop fuse is an essential and highly reliable short - circuit protection switch, specifically designed for 12kV distribution line branches and distribution transformers. It has been widely adopted in 12kV distribution lines and on the primary side of distribution transformers, serving the purposes of protection, equipment investment management, and cutting operations.Product OverviewAs the most commonly used short - circuit protection device in 12kV power distribution systems, this drop fuse combines economy, easy operation, and excellent adaptability to outdoor environments. It plays a crucial role in safeguarding the stability and safety of power distribution networks.Rigorous and Rational Overall StructureThe fuse is designed with a highly rigorous and rational overall structure. High - quality materials are selected, and the assembly process is strictly controlled. All components are stable, reliable, and feature flexible operation. This not only guarantees the reliable operation of the product during normal and fault conditions but also ensures that operators can easily and conveniently perform operations, reducing the risk of human - error during handling.High - Quality Materials and Advanced ProcessingAll accessories are not only designed reasonably but also made from high - quality materials using advanced processing technologies. This results in products with high precision and excellent interchangeability, ensuring the overall high - quality performance of the fuse. The use of such materials and processes enhances the durability and long - term reliability of the product, reducing maintenance costs over its lifespan.Superior Mechanical Performance and Fault - Breaking CapacityDuring full - gate operation, the melting tube moves precisely into place without shaking, bouncing, or tripping unexpectedly. The tripping action is highly reliable and is independent of the magnitude of the fault current. This fuse is capable of breaking a maximum short - circuit fault current of 16kA, providing effective protection against severe electrical faults and ensuring the integrity of the power distribution system.Anti - UV and Water - Resistant TubeThe melting tube is composed of an epoxy - resin glass - fiber winding tube and arc - dielectric materials. The outer layer is coated with anti - ultraviolet outdoor paint, endowing it with high mechanical strength and a long effective service life. Its geometric size is optimized, and the single - ended exhaust design accelerates the airflow speed, enhancing the arc - extinguishing ability. This allows the fuse to meet the requirements of breaking both large and small currents, adapting to various fault scenarios in the power distribution network.Silver Upper and Lower ContactsThe conductive contacts at both ends of the fuse feature a silver - on - silver structure. This design significantly reduces contact resistance, ensuring highly reliable electrical conductivity. By minimizing resistance, the risk of overheating and electrical failures due to poor contact is greatly reduced, improving the overall safety and efficiency of the power distribution system.High - Strength Silver - Plated Copper Trunnions and Cast Copper EarringsThe fuse is equipped with high - strength silver - plated copper trunnions and cast copper ear shells. The design ensures a tight and comfortable fit, with flexibility that prevents the melting tube from shaking during closure. This mechanical stability is crucial for the proper functioning of the fuse, especially during repeated operations and in harsh outdoor conditions.Parallel Trench TerminalThe casting and silver - plated parallel groove terminals provide two pressure line grooves, making wiring extremely simple and reliable. This user - friendly design simplifies the installation process, reduces installation time, and enhances the connection stability between the fuse and the power lines, contributing to the overall reliability of the power distribution system.Galvanized Ice HoodThe galvanized ice hood is designed to prevent rainwater from flowing over the stainless - steel spring and upper contacts. By doing so, it effectively prevents the top of the fuse from being immobilized due to freezing, ensuring that the fuse can operate properly even in cold and wet weather conditions. This feature is particularly important in regions with harsh winters and frequent icing.Elimination of Upper and Lower Diversion PiecesThe conductive parts at the upper and lower ends of the fuse are made of a single - piece silver - plated copper, eliminating middle break points. This design greatly improves the product's conductivity and reliability. Without break points, the risk of electrical resistance increase and connection failures is minimized, providing a more stable and efficient power - conducting path.Stainless - Steel Expansion Force Through the MandrelThe stainless - steel expansion force through the mandrel, made of a stainless - steel coil, ensures the stable and reliable connection between the melting tube and the casting copper trunnion. This connection stability is essential for the accurate operation of the fuse, guaranteeing that the melting tube can accurately drop when the fuse is activated, effectively cutting off the faulty circuit.In summary, our outdoor high - voltage AC drop fuse stands out for its advanced design, high - quality materials, and superior performance, making it an ideal choice for 12kV power distribution systems.
