Strcture of the EV bolt type fuses
The fuse tubes of electric vehicles are made of high temperature resistant ceramic materials, which have high fire resistance and solid hardness.
The melt is sealed in a smelting tube so that 99.99% of the pure silver becomes a variable cross section melt. The smelting pipe is filled with chemically treated high purity quartz sand and specially treated chemical materials for arc to extinguish agglomeration.
