    Hi,
    I have a burnt 500A fuse (taken from an outgoing of substation). When i chked it from inside it had silica for arc extinguishing and metal strips as a replacement of fuse wire. Can anyone explain what is the difference between using a metal strip and using a fuse wire.
    please help me...which is better of the two?
    thnx
