On the wire and cable wire and cable overhead due to the freezing technique outdoors, snow and ice covering the surface easily. When ice weighing more than the capacity of the wire and cable, it is easy to cause the transmission tower cable pull control cable prices, or to pull the poles, as well as the cable itself its breaking phenomenon. So, in order to avoid this from happening, there are two ways to relieve: 1. First, the choice of materials should be selected that can withstand the cold cable. Because of the gap on the snow falls between cable and cable, the cables tend to focus on the likely site of snow, resulting in a force, so that the cable is rotated, the snowball will snowball and eventually its breaking. Therefore, the cable is the main cause of the rotation icing. If the cable is a rigid conductor, when the snow piled more than enough time, not prone to twisting, snow will fall from the wire automatically. At the same time, due to the different cable hard density, when the snow gradually solidified to ice, to a certain extent it will be automatically broken. Therefore, some manufacturers will take advantage of the development of a new type of high-voltage overhead cables, which Aero-Z new high-voltage overhead conductors known to the world. The world's coldest countries Iceland and Czechoslovakia have adopted this AERO-Z wire. 2. Secondly, in the wire and cable coatings applied antifreeze. The so-called antifreeze paint, is a kind of high temperature insulation coating or reflective insulation coating. It aims to achieve frost insulation purposes. Further general also has a waterproof, corrosion, moisture, cracking, fire, insulation, and other functions. Specifications notation meaning specification using core number, the nominal cross-section and voltage level indicates ① single branch cable specification notation: the same loop of cables * (1 * nominal cross section), 0.6 / 1KV control cables, such as: 4 * (1 * 185) + 1 * 95 0.6 / 1KV, please visit: network transmission and distribution equipment more information visit ② multicore stranded branch cable specification notation: the same loop cable root number * nominal cross section control cable clamp, 0.6 / 1KV, such as: 4 ** 185 + 1 * 95 0.6 / 1KV ③ multi-core sheathed branch cable with standard notation: cable cores × nominal section -T, such as: 4 × 25-T whole spec notation because the branch cable contains trunk cable and feeder cables. And the two different specifications of structure, expressed in two methods: ① the trunk cable and drop cable respectively, such as: the trunk cable: FD-YJV-4 * (1 * 185) + 1 * 95 0.6 / 1KV drop cable: FD-YJV-4 * (1 * 25) + 1 * 16 0.6 / 1KV This method is particularly simple in design, can be easily expressed in different regional specifications ② the trunk cable and feeder cables together with representation, such as: FD- YJV-4 * (1 * 185/25) + 1 * 95/16 0.6 / 1KV method is relatively straightforward, but only in the case where the same kind of drop cable specifications, can not be represented with different specifications Extension: As the branch cable is mainly due to the 1KV low voltage distribution system, therefore, its rated voltage 0.6 / 1KV in the design of labels, can be omitted.
