بررسی قابلیت احتراق سیم بیش از حد به احتراق مجاور

In order to check the overload-wire's ignition capability to adjacent combustions, the aluminum and copper wires with sectional area of 1.5 mm2, 2.5 mm2 and 4 mm2 were used in experiment in different multiples overload current condition. From the experiment, the overload-wire's ignition capability to cotton clothes, fireproof pipes, waterproof boards were discovered. The results showed that overload-wire's ignition capability is directly proportional to overload current and time, but the effects of the type and sectional area of the wire on the ignition capability are multifaceted. The cotton cloths can be ignited while the fireproof pipes and waterproof boards only chard.
