Deep analysis of photovoltaic cable heating causes and consequences

The reasons for heating of photovoltaic cables during operation are as follows:

1. The resistance of the cable conductor does not meet the requirements, resulting in the heat of the cable during operation.

2. Improper selection of photovoltaic cable type causes the conductor section of the cable used to be too small, and overload occurs during operation. After a long time of use, the heat and heat dissipation of the cable will be unbalanced and cause heat.

3. The installation of photovoltaic cable is too dense, the ventilation and heat dissipation effect is not good, or the distance between the cable and other heat sources is too close, which affects the normal heat dissipation of the cable, and may also lead to the heating of the cable during the operation.
