Long term stretching of auto control cables can indeed affect their performance. This is mainly because cables are designed with a certain degree of flexibility and durability in mind, but prolonged stretching can exceed their normal design range, cause to a series of problems.
Firstly, prolonged stretching can alter the internal structure of the cable, including the conductor, insulation layer, and other internal components. This structural change may cause to a decrease in the conductivity of the cable, damage to its insulation performance, and even cause electrical faults such as short circuits.
Secondly, stretching may also have a negative impact on the mechanical properties of the cable. The protective layer and outer sheath of the cable may be damaged during the stretching process, resulting in a decrease in the cable's wear resistance, corrosion resistance, and tensile strength. These changes will make the cable more susceptible to external environmental influences, thereby shortening its service life.
In addition, prolonged stretching may have adverse effects on the signal transmission performance of the cable. For cables that transmit control signals, stretching may cause signal attenuation, distortion, or interruption, thereby affecting the normal operation of the car control system.
In summary, in order to ensure the stability and reliability of auto control cables, prolonged stretching should be avoided. During installation and use, strictly follow the manufacturer's instructions to avoid excessive bending, stretching, or twisting of the cable. At the same time, regular inspection of the status of cables, timely detection and handling of possible problems, is also an important measure to ensure the performance of cable use.
