XSD Cable: Cope Photovoltaic Cable Heat of Those Things

Photovoltaic cable normal power, the cable itself will produce a certain amount of heat, so you can not panic, because this is a normal phenomenon. But due to other special reasons, such as cable quality or cable specifications improperly selected and the installation and laying process is not standardized, etc. caused by the cable overheating that can be interpreted as the existence of greater safety risks, the next,XSD Cable will give you some knowledge of cable overheating, let's learn about it.

Firstly, the causes of cable overheating

1, The cable conductor resistance does not meet the standard requirements, resulting in cable heating in the process of operation.

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

3, The cable installation is too dense, ventilation and heat dissipation effect is not good, or the cable and other heat sources too close to the distance, will affect the normal heat dissipation of the cable, resulting in the cable in the process of running hot.

Secondly, the harm of overheating photovoltaic cable

After the cable overheating, if the cause is not identified and timely troubleshooting, the cable will continue to energize the insulation thermal aging phenomenon will occur, causing a cable short circuit, phase tripping, may cause a serious fire.

Thirdly, to prevent wire and cable overheating measures

1, According to the size of all the load, a reasonable choice of cable type specifications.

2, Choose a good brand, high reputation of the cable manufacturer to ensure that the quality of cable qualified.

3, Installation and laying of cables to ensure that the cable has a good ventilation and heat dissipation effect.

In addition to laying and use, the heat of the cable is also directly related to the quality of the cable, in order to reduce the cable heat as much as possible, XSD cable adhere to the use of high purity oxygen-free copper as raw materials, both to reduce the cable resistance, but also reduce the heat. Compared with ordinary cable, it has higher load capacity. With polyethylene as the insulation material, the cable also has high mechanical strength, good environmental stress resistance, excellent electrical performance, chemical corrosion resistance, etc., effectively reducing the short circuit, overload, heat generation and other problems caused by fire.
