The control cable is a distribution point of the power system directly to the electrical energy to various electrical equipment needs power connection lines. The cables we use in our daily life are generally divided into high-voltage and low-voltage. If you are using a high voltage cable, you will find that there is a layer of resin-like filler inside the cable, which acts as an insulator. This is an essential part of high voltage cables. In contrast, low-voltage cables don't have this, but they do have ribbons that are wrapped around them to hold each core in place and fill in the gaps.
