WESTKING will introduce you to the structure of the AUTOMOTIVE GRADE EVFUSE, which is significantly different from other factories, and it is a fuse structure specifically designed for new energy electric vehicles.

1-The metal end cap and purple copper legs are robustly secured via riveting and re-welding to guarantee their stability against vibration.

2-The fuse tube is fabricated from high-alumina ceramic, capable of enduring electric arc exposure and sustaining its shape under high temperatures.

3-The fuse element is crafted from imported Japanese alloy materials, guaranteeing its resilience to current stunts.

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

5-WESTKING's developed curing procedure is employed to solidify the quartz sand, preventing the fuse element from splitting due to vibrations and efficiently mitigating the intensity of electric arc impacts.

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