What are the causes of aging of energy storage power harnesses?

I. What are the reasons for the aging of the energy storage power harness?1. The ambient temperature where the energy storage power harness is located. Energy storage connector car electrical equipment according to the size of the load current to select the cross-sectional area of the wire used. Long working hours of electrical equipment can be selected wire the actual load capacity of 60%; short working hours of electrical equipment available wire the actual load capacity of 60% - A. Energy storage power harness is located in the external environment and the heat source is too high, the insulation breakdown, the seriousness of which will trigger A fire. Two chemical corrosion. Cable buried directly in areas with acid and alkali effect, often become the cable armor, lead skin or outer sheath is corroded, the protective layer due to long-term chemical corrosion or electrolytic corrosion, resulting in the failure of the protective layer, the insulation is reduced, but also lead to cable failure. 2, external damage. Analysis of the operation in recent years, especially in the rapid economic development of Hai Pu Dong, now a considerable number of cable failures are caused by mechanical damage. 3, cable joint failure. Cable joints is a weak link in the cable line A, by the direct fault of the personnel (poor construction) provoked by the cable joints failure occurs from time to time. Construction personnel in the production of cable joints in the process, if the joints crimping is not tight, heating is not sufficient and other original network, all will lead to the cable head insulation is reduced, thus provoking accidents.
