Let us introduce you to the WESTKING EVFUSE, the structure of a safe and reliable EV fuse should be like this

1-The metal end cap and purple copper legs are riveted and re-welded to ensure they will not fall off due to vibration.

2-The fuse tube is made of high-alumina ceramic, which withstands electric arc impact and does not deform under high temperatures.

3-The fuse element is precision-stamped from imported Japanese alloy materials, ensuring durability against current shock.

4-The arc extinguishing medium is high-purity quartz sand, which is selectively cleaned and processed.

5-A curing process developed by WESTKING is used to fix the quartz sand, preventing the fuse element from being pulled apart by vibrations and effectively reducing the intensity of electric arc impact.

6-An interference fit is used for the inner and outer end caps to reduce resistance.
