In recent years, there has been a lot of discussion on special cables in the domestic wire and cable industry. The main reason is that special cables have a high profit margin and a high threshold. A higher profit margin can help enterprises win more economic benefits. For large and powerful wire and cable production enterprises, a higher threshold can fully leverage their technological and financial advantages, Avoid homogeneous and low-priced competition with small and medium-sized cable production enterprises. However, the Chinese special cable market, or high-end cable market, is almost monopolized by foreign wholly-owned and joint venture companies. Coupled with China's unique consumer psychology of "favoring" imports, local special cables in China have not been able to fully leverage their advantages of "high-quality and cost-effective" in competition.

In the field of special cables, in recent years, environmentally friendly materials, aluminum alloy cables, aluminum rare earth optimization treatment, carbon fiber cables, high-temperature superconducting technology, and "thin and small processes" have all achieved good development. Moreover, according to the market, these technologies have a bright future in the coming years. And we also have reason to believe that as domestic cable production enterprises increase their research and development efforts in these technologies (processes) and produce qualified products, it can to some extent change the pattern of China's high-end cables being dominated by foreign forces, which will help to expand and strengthen the Chinese wire and cable industry.

Firstly, we can learn about environmentally friendly materials. In fact, the development of environmentally friendly materials conforms to market demand and also responds to the national call. At present, a large amount of polymer chemical materials such as rubber, polyvinyl chloride, and polyethylene are used in the production of wires and cables. A large amount of toxic and harmful gases are generated during the production process. Therefore, it is necessary to actively develop environmentally friendly materials and produce environmentally friendly wires and cables. After developing environmentally friendly wires and cables, cable companies such as Fujikura in Japan actively promoted the government's issuance of standards for environmentally friendly wire and cable products in order to monopolize the market. In recent years, the sales share of environmentally friendly wires and cables has rapidly expanded, and ordinary wires and cables and flame-retardant wires and cables are simply unable to compete with it. In addition, the leftover materials generated during the production process of wires and cables can be directly recycled and reused.

In addition, aluminum alloy cables have been booming in recent years, mainly due to the fact that the cable industry is a heavy material and light industry, coupled with the high price of the main raw material copper, which has led to high production costs for cables. Therefore, China actively introduces mature aluminum alloy cable production technology from abroad, and hopes to change the current situation of excessive cable production through this. Moreover, the conductivity of aluminum alloy cables is comparable to that of copper core cables, while their flexibility is superior to that of copper core cables. This changes the shortcomings of traditional pure aluminum cables such as poor mechanical strength, low fatigue resistance, and susceptibility to accidents at joints, ensuring the continuous stability of cable connections under long-term overload and overheating. It also compensates for the shortcomings of traditional copper cables such as memory effect and high rebound performance, Reduced line loss. In addition, regardless of the production, processing, manufacturing, transportation, installation, operation, and recycling of raw materials, aluminum alloy cables have incomparable economic and environmental advantages compared to traditional copper core cables, and are currently the best alternative to copper wire cables.
