Hainan wire & cable
Because wires and cables are overhead outdoors, the surface is easily covered with snow and ice. When the weight of ice exceeds the bearing capacity of wires and cables, it is easy to cause the cable to pull the transmission tower, or pull the telephone pole, and the cable itself collapses. Then, in order to avoid this situation, there are two ways to alleviate the Far East wire and cable:
First of all, in the choice of materials, we should pay attention to the choice of cables that can withstand the cold. As the snow and ice fall on the cables and in the gaps between cables, the center of gravity of the cables tends to deviate to the snow-covered parts, thus generating a force to make the cables rotate, and the snowball will roll bigger and bigger and eventually break. Therefore, the cable rotation is the main cause of icing.
If the cable is a hard conductor, when the snow accumulates enough, it is not easy to twist, and the snow will automatically fall off the conductor. At the same time, due to the different hardness and density of the cable, when the snow gradually solidifies to the ice, it will automatically break up to a certain extent. Therefore, some manufacturers have developed a new type of high-voltage overhead cable, among which Aero-Z new high-voltage overhead conductor is famous in the world. This kind of AERO-Z conductor is used in Iceland and Czechoslovakia, which are cold in the world.
Secondly, apply antifreeze paint on wires and cables. The so-called antifreeze coating is actually a kind of high-temperature thermal insulation coating or a reflective thermal insulation coating. It aims to achieve the purpose of anti-freezing through heat preservation. In addition, it also has the functions of waterproof, anti-corrosion, moisture-proof, crack-proof, fire prevention and insulation.
