The initial stage of any new technology, new technology and new thing will face a lot of denial and repudiation, but as the history goes forward, the old idea will be eliminated, the new things will be accepted and accepted by people, and then appear in every corner of the society, aluminum alloy cable. It's a good example.

 

For a long time, it is believed that copper is used in cable as a conductor, and its electrical performance and stability have a great advantage over other materials. Therefore, copper has always been a choice of wire and cable raw materials. However, based on the actual situation of less copper and less aluminum in China, in addition to the national strategic vision of advocating energy saving and advocating sustainable development, the more economical and more environmentally friendly aluminum will be the first choice of the cable raw materials. Therefore, a number of visionary, powerful enterprises, early on began the development and research of aluminum alloy cable project, and achieved good results.

 

Many non professionals think that aluminum is a connecting material with poor performance stability, so they always reject aluminum cables. But the reason is not because of the metal properties of aluminum itself, but also in the production process and installation technology. Now, due to the great progress and wide application of alloy technology, the performance of aluminum alloy conductor is much better than that of pure aluminum conductor. The new aluminum cables add metal elements such as iron and magnesium to the pure aluminum, keep the excellent electrical properties of the aluminum, and achieve the overall surpassing of the copper cable in flexibility, yield strength and corrosion resistance.

According to the experts of cable related, aluminum alloy cable is more obvious than copper cable. Because of its own density is far less than copper, the quality of aluminum alloy cable is only about 50% of copper cable under the same conductivity, so it is more convenient and convenient for engineering use. On the most controversial cable connection performance, the aluminum alloy cable greatly reduces the thermal and compressive creep of the conductor through the special alloy formula and heat treatment technology, which makes the aluminum alloy cable have more than copper cable connection performance.

As early as many years ago, the performance of alloy wires and cables has passed the rigorous test of national standard GB/T9327. Now, as a result of good economic and electrical performance, more and more national construction units, engineering designers, private owners have begun to pay attention to aluminum alloy cables, and in the state, it has also made many good policies for the further development of aluminum alloy cables for enterprises. In the future, aluminium alloy cable, which conforms to China's national conditions and meets the needs of Engineering construction, will have broad market prospects and strong vitality.
