Wire and cable is the basic facility for transmitting electricity to every household or organization. Without it, we enjoy a modern life without electricity. However, precisely because it is laid out in our work and living environment, it also brings certain hidden dangers to our lives, life and work. Whether it is at home or abroad, due to the number of fires caused by overheating of wire and cable, what is the cause of the wire and cable overheating and causing fire? The following wire and cable manufacturers will give you a good introduction to the factors that cause the wire and cable to overheat? This way everyone can take precautions.

Wire and Cable

1. The cable conductor resistance does not meet the requirements, which will cause the cable to overheat during operation. There is also a cable selection type that is improper. The conductor cross section of the cable used is too small, and overload occurs during operation. After a long time of use, the heat and heat dissipation of the cable are unbalanced and cause overheating.

2. The partial sheath of the armored cable is damaged. After entering the water, the insulation performance is slowly destructive, resulting in a gradual decrease in the insulation resistance, which may also cause overheating during the operation of the cable.

3. When the cable is installed, the arrangement is too dense, the ventilation and heat dissipation effect is not good, or the cable is too close to other heat sources, which affects the normal heat dissipation of the cable, and may also cause the cable to overheat during operation.

4. The joint manufacturing technology is not good, the crimping is not tight, and the contact resistance at the joint is too large, which may cause the cable to overheat. The insulation between the phases of the cable is not good, resulting in a small insulation resistance and overheating during operation.

See the above mentioned wire and cable manufacturers, as long as we usually choose a regular manufacturer when buying cables, buy high-quality wire and cable, and install the appropriate cable according to the actual project or project. When wiring is installed, it is scientific and reasonable. Then it will not easily lead to overheating of the cable or even a fire.
