Tightly winding the DC power cord around the object can cause the wire to be misinterpreted inside insulator, posing a DC power cable fatigue. Experts pointed out: "If the natural bending of the DC power cord is exceeded, excessively tight coiling will cause the entire DC power cable to become fatigued, which constitutes a misunderstanding." That is to say, whether it is a wire or an insulating case, it will burden unnecessary pressure.
The DC power cord should be twisted in a natural way. Although it looks a bit messy and takes up more space, it can be used to extend the life of the power supply. "The pressure of the ignition that occurs in the coil will cause the DC power cord to temporarily become badly contacted or even completely destroyed. When the time is coiled, the DC power cord will be subjected to excessive force, which will cause the two ends to fall, leak or contact poorly, and then greatly affect the life of the DC power cord."
Therefore, the most accurate method is to leave the DC power cord a certain length before the binding, which can be used to reduce the tight binding of 90 degrees and bring in a small amount of tension.
Regular maintenance can make the DC power cord work properly. In the long run, it can also reduce the waste of power resources, saving resources and reducing many expenses in the long run. If the DC power cable is protected in place within a certain range, the use process will be smoother and the fault will not easily occur.
The correct protection can effectively solve the oxidation problem and insulation protection of the DC power line. It provides an effective guarantee for the safety performance of the use process. Careful friends will find that when the DC power cord is used, the aging of the insulating material occurs when the DC power cord is used for a long time. Such a situation will not only cause a waste of current, but also have potential safety hazards and have a certain impact on the surrounding environment. If you usually develop a good habit of maintaining the DC power cord, then at least you can reduce the duration of its insulation aging.
