Causes of Fire Caused by Wires and Cables

Cables and wires cause fires mainly because of overload, short circuit, excessive touch resistance and external heat source effect.

(1) Fire temperature is generally 800 ~1000 C. In case of fire, conductor cable will lose its insulation ability quickly, which will lead to secondary electrical accidents such as short circuit, causing greater losses;

(2) Conductor cables have greater overload capacity under the allowable carrying capacity of the rules;

(3) Under short-circuit condition, the conductor cable will cause instantaneous melting and burning of insulation data and ignite surrounding combustibles.
