The Huajidian Electric Drop-out Fuse is an outdoor overcurrent protection device designed for overhead distribution lines operating at 6kV to 33kV. Featuring a high-insulation polymer or porcelain housing and an automatic drop-out fault indication mechanism, the fuse complies with international IEC standards and provides reliable protection for power distribution networks.
As a professional electrical equipment supplier, Huajidian sources its drop-out fuses from a certified manufacturing facility in Yueqing, China. Every product undergoes comprehensive factory acceptance testing (FAT) and is supplied with complete certification documentation and global after-sales support. The product is widely used by utility companies, EPC contractors, and power distribution projects across Southeast Asia, the Middle East, Africa, and North America.
The fuse tube utilizes an efficient gas-generated arc extinguishing system that interrupts fault currents within approximately 0.2 seconds. Rapid fault isolation minimizes damage to downstream electrical equipment and improves overall system reliability.
The automatic gravity-operated drop-out mechanism creates a clearly visible open circuit after fuse operation, allowing maintenance personnel to quickly identify fault locations while improving operational safety during inspection and maintenance.
Manufactured with corrosion-resistant metal components and high-performance insulating materials, the fuse operates reliably in temperatures ranging from -30°C to +60°C. Optional silicone-coated polymer insulators provide excellent resistance to pollution, UV exposure, humidity, and coastal salt spray conditions.
Multiple fuse current ratings are available to match transformers of different capacities. Huajidian also provides customized bracket dimensions, mounting configurations, and OEM manufacturing services to meet specific project requirements.
Every Electric Drop-out Fuse is manufactured under a comprehensive quality management system that includes incoming material inspection (IQC), in-process quality control (IPQC), and full-function Factory Acceptance Testing (FAT) before shipment, ensuring consistent product quality and long-term reliability.
