For the cable factory, the cable production process is nothing but a big problem. How do you spend the cable in the cold winter every year? Cable antifreeze technology is undoubtedly our topic of concern, how to do cable antifreeze, what are the skills? Today we look at it:
Since the wire and cable are overhead, the surface is easy to cover snow and ice. When the weight of the ice layer exceeds the capacity of the wire and cable, it is easy to cause the cable to pull the transmission tower, or pull the utility pole, and the cable itself collapses. Then, in order to avoid this happening,
There are two ways to mitigate:
1. First, pay attention to the choice of materials to protect against cold cables. As the snow falls on the cable and the gap between the cables, the center of gravity of the cable tends to be biased toward the snowy part, creating a force that causes the cable to spin and the snowball to roll and eventually collapse.
Therefore, cable rotation is the most important cause of ice coating. And if the cable is a hard conductor, when the snow is piled up enough, it is not easy to twist, and the snow will automatically fall off the wire. At the same time, due to the different hard density of the cable, when the snow gradually solidifies to the ice, it reaches one.
The degree will be automatically broken. Therefore, some manufacturers have developed a new type of high-voltage aerial cable, which is known as Aero-Z new high-voltage overhead conductor. The AERO-Z wire is used in Iceland and Czechoslovakia, the coldest countries in the world.
2. Secondly, apply antifreeze coating to the wire and cable. The so-called antifreeze coating is actually a high temperature thermal insulation coating or a reflective thermal insulation coating. It aims to achieve antifreeze by keeping warm. In addition, it is generally waterproof, anti-corrosive, moisture-proof, crack-proof, fireproof, and insulated.
And other functions.
Antifreeze coatings on the market vary according to the research and development capabilities of each company. Therefore, you need to add more comparisons and inspections when purchasing.
