Such cables typically operate at voltages below 500V ac and 1000V dc. The current is not large and the load is intermittent, so the section is small, and is generally 1.5-10 mm. The control cable may be classified into an oil-impregnated paper insulated control cable, a rubber insulated control cable, a plastic insulated control cable, and the like, depending on the insulating material. One of the most common problems of the existing control cable is the occurrence of breakage, and the main factors causing the breakage of the control cable are as follows: cable fatigue caused by long-term use and insufficient strength of the cable itself.
