Cables will age with the increase of usage time. Aging is not a problem. Faults of aging are problems. In fact, many cable aging faults can be avoided. To avoid these situations, the cable will be used longer. The most direct cause of aging failure is insulation breakdown and breakdown. There are many factors reducing the conductivity of the conductive insulation. According to the actual operating experience, LINA is summarized in the following cases.
1.External Force Injury
From the operational analysis in recent years, especially in areas where the economy is developing at a high speed, quite a number of cable failures are caused by mechanical damage.
