Causes and solutions for overheating of wires and cables

[Abstract]:
When the power cable passes through a certain load current, it will generate heat. As the load current increases, the surface temperature of the cable will be higher. Such as: polyvinyl chloride (PVC) cable, is the core temperature 70 degrees for the upper limit, the surface temperature will be low 5 ~ 10 degrees. Therefore, the cable surface temperature below 60 degrees is basically safe, from the perspective of power maintenance, of course, the lower the better.
