High Voltage Fuses Production

Functions

  • Automatic self-recovery: Cuts off power frequency follow current after overvoltage elimination, with a waterproof design ensuring stable performance.
  • Inverse-time overload protection: Features typical K-type fusing characteristic (inverse time-lag), with long fusing time under small overload current and rapid fusing under large overload current, adapting to the normal start-up current impact of general electrical equipment and avoiding false tripping.
  • Reliable short-circuit protection: Quickly responds to short-circuit current, fusing instantly to cut off the fault circuit, preventing electrical equipment and lines from being damaged by large short-circuit currents.
  • Efficient arc extinction: Equipped with quartz sand arc-extinguishing filler, which rapidly absorbs arc energy during fusing, suppressing arc extension and overvoltage, ensuring safe and smooth circuit breaking.
  • Stable insulation performance: Complies with IEC 60269/GB/T 13539 standards, with excellent insulation between the fuse body and the shell, eliminating the risk of electric leakage and insulation breakdown under normal working conditions.

Customize the production of goods by using different materials according to requests to meet specific needs. This includes options for the fuse housing, the fuse element, and the fuse cap.

Color Selection

Ceramic bodies are available in white and brown. Epoxy tubes are available in green, white, black, yellow, brown, and gray.

Packaging Options

We offer products with smooth surface packaging, carton packaging, and wooden packaging. By default, we use packaging with our standard logo, but we also provide neutral packaging or packaging with the customer's own logo upon request.

Materials and Customization Options

Our Manufacturing Facilities

The factory features its own component manufacturing workshop, production workshop, assembly workshop, laboratory, finished product warehouse, semi-finished product warehouse, and raw material warehouse. For the component parts of our products, we manage production internally. We only use first-hand materials and commit to not reusing materials or using second-hand materials. Our materials (including copper, brass, aluminum, iron, tin, zinc, nickel, stainless steel, silicone rubber, and ceramics) are all purchased from official state units to ensure high quality and safety.
