As we know, the temperature of the power cable depends on a load of current, and the process should be completed in time to avoid lethal consequences. For instance, a polyvinyl chloride (PVC) cable entails a core temperature of 70 degrees as the upper limit, and the external temperature is 5 to 10 degrees lower. Consequently, the external cable temperature is safe below 60 degrees. However, do you know the why the electrical wire cable may be getting hot?

The main reasons for the heating of the cable during maneuver are as follows:

1. When the cable conductor confrontation does not meet the supplies, it would cause the cable to generate heat during operation.

2. The use of improper cable type could be damaging. When the conductor cross-section of the cable to be used is unusually small, and a surplus phenomenon occurs during operation. With the usage of time, the heat generation and heat indulgence of the cable are unhinged to cause heat generation.

3. When there is a lack of ventilation and heat dissipation, cable installation arrangement is compressed and cables are too close with each other the effects would be shown in hot cables.

4. The joint manufacturing technology necessitates brilliance and depends on these factors.

· Incorrect crimping

· Contact resistance at the joint is huge which may cause the cable to generate heat.

· Cable phase insulation performance is not desirable. It results in less insulation resistance; heating will also occur during operation.

6. The fractional casing of the steel-clad cable is damaged. Moreover, water is destructive for the insulation process, resulting in a gradual decrease in the insulation resistance, which will also cause cables to heat up.
