Study on Insulation Tension and Damage of Control Cable

The control cable is the power connection line that directly transmits electric energy to various electrical equipment and appliances from the distribution point of the power system. In the process of cable construction and use, there are many kinds of failures, and the causes of failures are also different. Among them, the insulation stretching and damage caused by external forces are the main causes of control cable failures. The finite element simulation software is used to simulate the cable stretching and damage defects, and analyze the wave impedance variation law of different defect degrees, which is helpful to analyze the cable fault and evaluate the cable service life.
