Electricity accompanies the tropical fire reason analysis

　　Electricity accompanies heat is a common heating method, which is widely used in industry and residential area. However, electric accompanying heat equipment also exists certain safety hidden danger, improper use will cause fire. So, what are the reasons that cause electric accompanying heat to catch fire?

　　1. the electric accompanies the heat insulation to be damaged, the cable connection is bad or the electrical component aging and so on the reason will cause the short circuit phenomenon, causes the short circuit at the electric current to increase greatly, causes the electric accompanies the heat temperature to rise, thus causes the fire.

　　2. the electric accompanies the tropical tail must use the tail end junction box to seal, if the electric tropical tail leaks does not install the junction box, the tail end once damp, easy to cause a short circuit, lead to fire.

　　4. installs the tail end junction box, should the outer sheath strips, will the shielding layer strips, forbids the electric heat tape shielding layer to access the tail end junction box, the shielding network such as accessing the junction box, will cause the circuit to ground, in the ground protection contact bad state, easy to produce the electric spark, triggers the fire phenomenon.

　　5、The design and manufacturing quality of the electric accompanying heat equipment itself will also have an effect on the fire at the end. For example, the electric wire and plug of the electric heating equipment must be matched, and the contact between the plug and the socket must be good, otherwise it is easy to have poor contact or the plug falls off and other problems, thus causing fire.

　　6. the electric accompanies the tropical end to use the water-absorbent insulating tape, causes the end to be damp, triggers the leakage to start the fire because the end is damp, in the electric heating process, the water will be heated to evaporate so as to form the high pressure. Leakage occurs when the insulation of the wires is unable to withstand such high pressure. If the leakage occurs in a humid place, it is easy to start a fire .
