Structure of fuse link

The fuse pipe is the main part of fuse, it is made by installing the fuse wire in the porcelain pipe, filing the quartzsand in the porcelain pipe and sealing to-ends of pipe.For the fuse pipe with rated current below 7.5Aand 35V ratedvoltage, its fuse wire is rolled on the special porcelain core, referening to chart 2.a. for the fuse pipe with rated currentabove 7.5A, its fuse wire is hang in the porcelain pipe,referening to the chart.
