Damaged outer skin
Fault description: The outer skin of the cable is physically damaged, such as scratches, cuts, tears, etc., exposing the internal wires and making them vulnerable to external environmental influences such as moisture, dust, chemicals, etc., further leading to a decrease in electrical performance or failure.
Cause: During the vehicle assembly process, it may be scratched by tools or other components; Friction and collision between cables and components such as the body and chassis during vehicle operation; Or be bitten by small animals such as mice.
Cable aging
Fault description: With the increase of usage time and the influence of the usage environment, the insulation layer and sheath materials of the cable will gradually age, resulting in hardening, brittleness, cracking and other phenomena, which will reduce the performance and reliability of the cable.
Causes: Long term exposure to harsh environments such as high temperature, low temperature, humidity, and ultraviolet radiation accelerates the aging process of cable materials; Meanwhile, cables are constantly subjected to mechanical stresses such as vibration and tension during vehicle operation, which can also promote material aging.
