Factory Facility

Functions

  • Automatic self-recovery: Cuts off power frequency follow current after overvoltage elimination, with 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, fuses instantly to cut off the fault circuit, preventing electrical equipment and lines from being damaged by large short-circuit current.
  • Efficient arc extinction: Equipped with quartz sand arc-extinguishing filler, which rapidly absorbs arc energy during fusing, suppresses 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 in normal working conditions.

Customization & Materials

Materials Selection
Customize the production of goods by using different materials according to the customers' requests, in order to meet their needs. Including the selection of the fuse housing, the selection of the fuse element, and the selection of the fuse cap.
Color Selection
The ceramic vases are available in white and brown colors. The epoxy tubes are available in colors such as green, white, black, yellow, brown, and gray.
Packaging Options
We offer products with smooth surface packaging, as well as carton packaging and wooden packaging. By default, we use packaging with our standard logo. We can also provide neutral packaging or packaging with the customer's own logo upon request.

The factory has its own component manufacturing workshop, production workshop, assembly workshop, laboratory, finished product warehouse, semi-finished product warehouse, and raw material warehouse. For the component part of our products, we produce them ourselves. We only use first-hand materials and promise not to reuse materials or use 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.

We have extensive export experience, including assisting customers in formulating shipping plans, facilitating customs clearance, and providing solutions for potential challenges. We help customers develop container loading plans to find the optimal solution within the limited space and weight constraints, securing more benefits for the customers.
