Cable brand: aluminum alloy cable knowledge introduction
Release time： 2022-06-27 11:04
The development of China's cable industry has been relatively extensive, cable has accounted for 1/10 of the industry, according to the different conductive materials can be divided into aluminum core, copper core and aluminum alloy. With the continuous development of science and technology, electrical and mechanical properties are also improving, in Europe and the United States and other developed areas with aluminum alloy cable, has been applied for more than 40 years, accounting for 90% of the total cable.
Aluminum alloy cable brand advantage is that the material is very good, is on the basis of pure aluminum above the addition of a number of elements, such as iron copper silicon and other alloy materials. Through the special process, and after annealing treatment, greatly improve the overall physical mechanism capacity. The second point is that the electrical performance is relatively strong, the conductivity of aluminum alloy is more commonly used, the 61.5 load flow of the material is the same as 79, and the section is more than the other flow.
Aluminum alloy cable brand performance is relatively strong, can make up for the lack of other products less electricity system is relatively strong, under the same load capacity to provide conduction. In addition, the flexibility of aluminum alloy is 30% higher than that of copper, and the bending degree is strong. After the use of aluminum alloy, the force is relatively small, the tension is small, and the resilience is lower than other things. Therefore, it is reliable, safe and effective, and the anti-creep ability can be increased by 300%, avoiding the problem of relaxation.
Aluminum alloy cable brand corrosion resistance is also relatively strong, when aluminum and air contact will form a layer of oxidation layer, this oxidation layer is relatively corrosion resistant, then add a little inside this element can resist corrosion may be a little better. It has good corrosion resistance to multiple environments, is safe and reliable, and is a better material among cable brands. But also has flame retardant insulation performance, aluminum alloy cable is made of environmentally friendly crosslinked polyethylene material.
Longer service life is better than PVC, and the safety performance can be guaranteed. Combined with the unique metal armor structure, it meets the needs of low carbon smokeless and reduces the overall fire risk factor. In some large photovoltaic stations, the use of aluminum alloy cable brand as AC cable, the total cost is very low, the effect is relatively good, the price is so good, in line with the total cost of demand.
Guangdong Changjiang Cable Co., Ltd. is a large scale wire and cable manufacturers, more elegant, plant design is very reasonable, advanced equipment and technical force is also very strong. Has a strong production capacity, with more perfect management means, equipped with professional inspection equipment and technical personnel, for each batch of products will be multi-directional identification, can make the quality standards, product quality by the insurance company is assumed, to ensure the praise of cable.
