Development history of wires and cables

China is at a stage of rapid development, and the rejuvenation of the Chinese nation is also an important task for the leaders of our country. Because neither daily life nor modern military power can be separated from power resources, so can not be separated from wires and cables. Wire and cable play an irreplaceable role. The quality of wires and cables determines the stability of power, and power determines productivity. Therefore, only the quality of wires and cables can improve the development productivity.
The conductive part of the wire is the core wire, and the most commonly used materials in daily life are copper and aluminum. Among many metals, silver has the best conductivity, copper slightly takes the second place, and gold and aluminum occupy the third and fourth places respectively. However, silver and gold are rarely used because of their high price, while aluminum is widely used because of its low price and light weight. As an ideal wire material, copper is very popular because of its high melting point, good thermal conductivity and tensile properties, and high safety.
For the sake of safety and the requirement of conductivity, more and more projects and occasions encourage and promote the use of copper wire. At present, the electrical materials of commercial buildings in China are basically copper cables, and copper wire is the first choice of most people when decorating the home. With the improvement of living standards, the increasing number of electrical appliances and the increasing demand for electricity, the importance of high-quality cables is self-evident, and the choice of copper cables also means an additional security. And copper is a "green" metal, which is very convenient and economical to recycle. Choosing copper wire also helps to reduce resource consumption and protect the ecological environment.
With the continuous progress of science and technology, the presentation of wires and cables is becoming more and more subtle, but its importance in our daily life is irreplaceable, and it will accompany mankind to the future.
