In recent years, the discussion on the special cable of the domestic wire and cable industry is more, the main reason is that the special cable has a higher profit margin and higher threshold, higher profit margins can help enterprises gain more economic benefits, but the higher threshold for wire and cable production enterprises of large and powerful, can give full play to the technical the advantage and capital advantage, avoid competition, and small and medium-sized cable production enterprises homogeneous low price competition. But China special cable market or high-end cable market is almost solely foreign-owned companies and joint ventures monopoly, plus China's "preference" import such a unique consumer psychology, so the local China special cable in the competition is not able to give full play to the advantages of "quality".
In the special cable, in recent years, environmental protection material, Aluminum Alloy cable, Al re optimization, carbon fiber cables, high temperature superconducting technology and "small craft" have been a good development, and according to the market, in the next few years, the prospect of the technology of light. But we also have reason to believe that, with the domestic cable production enterprises in the technology (process) to increase R & D and production of qualified products, to a certain extent change China high-end cable was occupied by foreign forces pattern, will help Chinese wire and cable industry bigger and stronger.
First of all, we can first understand the environmental protection materials. In fact, the development of environmentally friendly materials to comply with market demand, but also in response to national calls. At present, the production of wires and cables, a large number of rubber, PVC, polyethylene and other polymer chemicals. A large number of poisonous and harmful gases are produced in the process of production. Therefore, we should actively develop environmentally-friendly materials, production of environmentally friendly wire and cable. Japan's Fujikura cable companies in the development of the environmental protection wires and cables, in order to monopolize the market, and actively promote the government environmental protection type of wire and cable products standards. In recent years, the share of environmentally friendly wires and cables has expanded rapidly, and ordinary wires, cables and flame retardant wires and cables are simply not competing with them. In addition, the leftover materials produced in the process of wire and cable production can be directly recovered and reused.
In addition, in recent years Aluminum Alloy cable are popular, the main reason is that the cable industry is a heavy material light industry, coupled with the main raw materials of copper prices higher, thus has high production cost caused by the cable. To this end, China has actively introduced foreign countries already developed quite mature aluminum alloy cable production technology, and hope to change the status of cable production too high. Moreover, Aluminum Alloy cable conductive properties and copper core cable flexibility is compared to be roughly the same, copper core cable better, change the shortcoming of pure aluminum cable has poor mechanical strength, anti fatigue ability is low, the joint accident prone, guarantee the sustained stability of cable overload and overheat in long time under the condition of cable connection also, make up the traditional copper cable with memory effect and high rebound performance defects, reduce the line loss. In addition, in terms of raw material production, processing, manufacturing and transportation, installation, operation, recovery, Aluminum Alloy cable has the incomparable advantages of economy and environmental protection than traditional copper cables, as is currently the best substitute of copper cable.
In the optimization of aluminum rare earth, it is a hot technology in the cable industry. As we all know, the production of aluminum rods by continuous casting and rolling process has become very popular in China, and the performance is also good. But as the equipment remained at its early 70s levels, there was little technological innovation. Therefore, we must actively promote the optimization of processing technology of aluminum rare earth of China, and the introduction of some key equipment and technology of aluminum zirconium alloy, the aluminum melting stove into molten aluminum fuel oil or natural gas furnace, the total elimination of aluminum melting stove coal smoke and flue gas emissions, and set the flue gas purification of flue gas device, improve the emission quality, increase yield and reduce costs, while the wire working temperature is increased from 70 to 150 DEG C., carrying capacity is increased by 1.6 times.
