The following Guangxi cable manufacturers will take you to understand the reasons for the heating of power cables during operation:
1. The conductor resistance of the cable does meet the requirements, which causes the cable to generate heat during operation.
2. Improper selection of cables leads to too small conductor cross-section of the cables used, resulting in overload during operation. After long-term use, the heating heat dissipation of the cables are unbalanced, resulting in heat generation.
3. The arrangement of cables is too dense during installation, the ventilation heat dissipation effect is good, the cables are too close to other heat sources, which affects the normal heat dissipation of the cables, also causes the cables to generate heat during operation.
4. The joint manufacturing technology is good, the crimping is tight, which leads to excessive contact resistance at the joint, also causes the cable to generate heat.
5. The insulation performance between the phases of the cable is good, resulting in a small insulation resistance heating during operation.
6. The partial sheath of the armored cable is damaged, which will cause slow damage to the insulation performance after entering the water, causing the insulation resistance to gradually decrease, will also cause the cable to generate heat during operation.
