Why not use copper wire, wire instead of fuse?
Thus, an important role in protection of power line and fuse with the electric appliances not to fire or burn out. So people give it a name - "fuse". Usually fuse fuse current is 1.5-2. times the rated current of the fuse. In the operation of the temperature is less than 80-1000. when the current exceeds the rated current fuse 5 times the fuse will fuse, prison immediately. If the diameter of the fuse is too thick, or with copper wire, wire instead of a encountered and leakage, short circuit or overload, because the fuse current is too large and can not timely fuse.
Can not achieve the purpose of protection of power lines and electrical appliances. For a long time abnormal operation, will lead to electric monument line and electrical appliance heating, fire or burned, and then lead to R fuel, or even lead to fire
Fuses are equipped with a switchboard usually family, fuse with fuse, fuse with tin, lead antimony alloy material. It has the characteristics of low melting point, high resistance and fever. Through the wire and the use of electrical appliances when the current exceeds the allowable value of the song, the thermal effect of the current will the fuse fuse current "a fever, and reached the fuse fuse through it immediately to the melting point), so as to cut off the electric fuse. The role of clay.
