What causes wires to heat up?
The reasons for wire heating are as follows:
1, the conductor resistance of the wire does not meet the requirements, resulting in heat during the operation of the wire.
2. Improper selection of wire leads to too small section of wire conductor, resulting in overload during operation. After long-term use, the heat and heat dissipation of the wire are not balanced, leading to heat.
3. When installing the wires, the arrangement is too dense, the ventilation and heat dissipation effect is not good, or the wires are too close to other heat sources, which affects the normal heat dissipation of the wires, and may also cause the wires to generate heat in the process of operation.
4, the joint manufacturing process is not good, the crimping is not tight, leading to the contact resistance at the joint is too large, will also cause wire heating.
5, the insulation performance of the phase-to-phase wire is not good, resulting in low insulation resistance and heating during operation.
6, part of the wire sheath damage, water will cause slow damage to the insulation performance, resulting in the gradual reduction of insulation resistance, but also cause heat in the process of running the wire.
