XSD Cable:The Importance of Daily Testing PV Cables for You

Photovoltaic cable is often referred to as the main nerve of economic development, because it is not only related to the Internet information transmission and daily operation of the production industry, but also to our daily life, obviously, the cable is closely related to our lives, once the failure, it will have a huge impact on our normal order of life, therefore, China attaches great importance to the construction, operation and maintenance of the cable, but at present The quality of domestic photovoltaic cables is worrying. Therefore, do not fail to immediately worry that they bought a poor quality cable, first you should check the following common test items.

1. Cable performance test

This phase of the test is mainly conductor DC resistance, insulation resistance, finished voltage test and insulation core voltage test, each of this process is very important, where the conductor resistance directly reflects the electrical transmission performance of the cable, but also indirectly affect the temperature, life, voltage drop and operational safety of the cable in the charged operation, it is mainly to check the conductor material and cross-sectional area, if the conductor material is not good or If the conductor material is not good or the cable cross-sectional area is seriously insufficient, it will lead to the conductor DC resistance seriously exceed the standard.

Insulation resistance, finished voltage test and insulation core voltage test are to test the electrical insulation performance of the cable insulation layer and sheath layer, insulation resistance is to detect the resistance of the insulation material between the two conductors, it should be large enough to achieve insulation protection.

2. Cable mechanical performance test

The main purpose of this performance test is to test the tensile strength and elongation at break of the insulation and sheath plastic materials, including before and after aging, as well as the finished flexible cable bending test, bending test, load fracture test, insulation core tear test, etc. The tensile strength before and after aging, elongation at break before and after aging is the most important and basic index of cable insulation and sheathing materials, requiring that the materials used for cable insulation and sheathing have sufficient tensile strength, not easy to break at the same time must also have a certain degree of flexibility.

3, Insulation and sheathing materials performance testing

Including thermal weight loss, thermal shock, high-temperature pressure, low-temperature bending, low-temperature tensile, low-temperature impact, flame retardant performance, etc., these are tests of insulation and sheathing plastic material performance, cable flame retardant performance is very important to test the performance of the test for non-flame test, that is, the standard installation of finished cables with a special flame ignited for a certain period of time, the flame extinguished itself after checking the flame. Of course, the less the burning part the better, indicating that it is poor flammability, flame retardant, but also to ensure the quality of safety performance.

Well, for you to popularize so much about the daily detection of photovoltaic cable, you get it, if you still want to know more related news and information, we suggest to pay attention to our company XSD cable official website, the follow-up will continue to push more detailed information for you, please pay attention.
