XSD Cable: Take You A Deep Analysis of The Causes And Consequences of Photovoltaic Cable Heating

When the photovoltaic cable in the process of operation through a certain load current, will generate a certain amount of heat, with the increase in cable load current, the surface temperature of the cable will gradually higher, if not dealt with in a timely manner, the consequences can be imagined, such as PVC cable, to the core temperature of 70 degrees as the upper limit, the surface temperature will be 5-10 degrees lower, therefore, the surface temperature of photovoltaic cable in the following 60 degrees is basically safe from the power From the point of view of maintenance, the lower the temperature, the better.

Photovoltaic cable in the operation of the process of heating the following reasons.

1, The cable conductor resistance does not meet the requirements, resulting in the cable in the process of running hot.

2, Photovoltaic cable type improperly selected to cause the conductor cross-section of the cable used is too small, the operation of overload. After a long period of use, the heat and heat dissipation of the cable will be unbalanced and cause heat.

3, Photovoltaic cable installation is too dense, ventilation and heat dissipation effect is not good, or the cable and other heat sources are too close to affect the normal heat dissipation of the cable, may also lead to cable heating operation process.

4, The joint manufacturing process is not good, crimping is not tight, resulting in contact resistance at the joint is too large, the cable heating.

5, The cable phase insulation performance is not good, resulting in low insulation resistance, the operation of the heat.

After the cable is hot, if the cause is not identified, timely troubleshooting, the cable will continue to energize the insulation thermal breakdown will occur. This may lead to short circuit tripping of the cable, which may cause a fire. From the above reasons, we can see that cable heating is directly related to the quality of the cable, in order to avoid accidents, XSD cable will continue to develop and produce better quality cables for users, and strive to create a safer working and living environment for everyone. I hope you must shine your eyes and choose quality cables with quality assurance.
