1.Rated Specifications: Suitable for a rated frequency of 50Hz and voltage of 10kV, making it ideal for high-voltage applications.
2.Series Connection: Operates in series with the power line, ensuring that the fuse remains taut and locked during normal operation.
3.Fault Response Mechanism: Upon fault occurrence, the fuse melts and releases the movable joint, allowing the fuse tube to drop quickly and cut off the circuit.
4.Load Type Fuses: Enhanced design includes elastic contacts and arc-extinguishing covers for switching load currents in power systems, improving functionality and safety.
1.Fast Protection Response: The fuse melts rapidly during faults, unlocking the movable contact and causing the fuse tube to drop automatically, achieving quick fault isolation.
2.Simple and Reliable Structure: Fully mechanical operation, requires no external power supply or control, suitable for distribution lines without electrical control.
3.Combined Load Switching Function (Type F): Equipped with elastic contacts and arc extinguishing covers for safely switching load currents within the rated current.
4.Flexible Installation and Strong Adaptability: Suitable for 10 kV overhead lines, supports horizontal, inclined, or vertical installation, adaptable to various pole configurations.
1.Maintenance-Free Design: No moving electrical parts, requires no daily lubrication or adjustment, only periodic inspections and fuse status checks.
2.Quick and Easy Replacement: Modular fuse tube design allows rapid replacement after a fault without power outages or specialized tools.
3.No Auxiliary Power Required: Operates based on mechanical and thermal principles, independent of control power, reducing system support costs.
4.Long Service Life: Main structure made of high-strength composite materials and stainless steel components, with strong weather resistance and a service life of over 15 years.
1.Lightweight Packaging: Low single-unit weight, suitable for batch transportation, packaged in standard cartons or pallets with shock and moisture protection.
2.Ready-to-Install: Fully assembled and tested before shipment; on-site installation only requires fixing the bracket, connecting wires, and installing the fuse tube.
3.Comprehensive Installation Guidance: Provides illustrated installation manuals and video tutorials, with remote installation support available.
4.Global Logistics Support: Supports container, bulk, and air freight, with export packaging and documentation services.
1.All-Weather Protection Design: Fuse tube made of silicone rubber or composite materials, UV-resistant and anti-aging, stable operation in temperatures from -40℃ to +80℃.
2.Strong Short-Circuit Withstand Capability: Maximum rated short-circuit breaking current of 16 kA, short arcing time during interruption, and low arc energy.
3.Excellent Insulation Performance: Rated lightning impulse withstand voltage 125 kV, creepage distance ≥330 mm/kV, suitable for Class III and above polluted areas.
4.Reliable Mechanical Operation: Stable contact pressure, flexible locking mechanism, consistent fuse tube drop angle ensures accurate operation.
1.Precision Injection Molding and Die-Casting: Fuse tubes and metal components are mold-formed with high dimensional accuracy and consistent batch quality.
2.Comprehensive Testing System: Each batch undergoes full-item testing including power frequency withstand voltage, mechanical operation, and fuse characteristic tests.
3.Environmentally Friendly Surface Treatment: Metal parts treated with hot-dip galvanizing or Dacromet process, offering better corrosion resistance than ordinary electroplating.
4.Traceability Management: Implements fuse serial number management, records fusing characteristic curves, and supports fault analysis and quality traceability.
