What are the common quality problems of shared new energy cables?

I. What are the common quality problems of shared new energy cables?1. Unqualified structure. The thinnest point of the thickness of the insulation layer is lower than the minimum value specified in the standard, or the average thickness is lower than the nominal value, and there is a risk of breakdown when using it.2. Failure of cross-linking degree. Crosslinking degree does not meet the standard, the new energy cable heat resistance is not qualified, can not meet the requirements of 90 ℃ operating temperature, short-circuit allowed 250 ℃, the electrical performance is greatly reduced.3. Bamboo-shaped new energy cable thickness is not uniform, the new energy cable appearance of bamboo. Due to the different sections of the new energy cable cross-section, the new energy cable is not uniformly heated, affecting the insulation life.4. Surface scratches. Under normal circumstances, the surface scratches in the detection process of new energy cables will be eliminated, will not be listed, but the new energy cables in the transportation or laying process may still be scratched by foreign objects, so it is necessary to check the new energy cable insulation is intact before use. Normal wire new energy cable put into operation too long service life has reached the service life. Wire new energy cable itself and the center head of the insulation resistance decreases year by year, not up to the standard value of the rules, quality problems will also appear.
