What is the frost protection technology for mining cables?

Wires and cables are suspended outdoors with snow and ice covering their surfaces. When the weight of the ice exceeds the capacity of the wires and cables, the cables can simply pull the transmission towers to or from the poles, and the cables themselves can break in appearance. To prevent this, the following should be noted: the first thing to note is the choice of cable material. When ice and snow fall on the cable and in the gaps between the cables, the center of gravity of the cable is slightly tilted to the part with snow, and then the force causes the cable to rotate and the snowball to roll more and more and eventually break up. Therefore, cable rotation is the main cause of icing. If the cable is a solid conductor, the snow will automatically fall off the wire when there is enough snow (rather than simply changing). At the same time, since cables are stable and of different densities, they will automatically break up when snow gradually condenses on the ice and reaches a certain level. As a result, some manufacturers have developed a new type of high-voltage overhead cable. Next, antifreeze is applied to wires and cables. The so-called antifreeze coating is actually a high-temperature insulating coating, perhaps a reflective insulating coating. The purpose is to achieve freeze protection through insulation. Others are usually waterproof, corrosion resistant, moisture resistant, crack resistant, fire resistant and insulating.
