In recent years, the domestic wire and cable industry for special cables are more discussions, largely because of special cables have higher profit margins and a higher threshold, higher profit margins can help companies win more economic benefits and higher The threshold for large, powerful wire and cable manufacturers, to give full play to their own technological advantages and financial advantages, to avoid small and medium-sized cable manufacturers homogeneous competition, low-cost competition. However, the special cable market in China or the high-end cable market is almost exclusively monopolized by wholly foreign-owned companies and joint ventures. Coupled with China's "preference" to import such a unique consumer psychology, the Chinese local special cable has not been able to fully compete in terms of competition "Quality and cheap" advantage.
In the special cables, in recent years, environmental protection materials, aluminum cables, aluminum rare earth optimization, carbon fiber cables, high temperature superconducting technology and "thin and small technology" have been well developed, and according to the market, in the next few years , These technologies have a bright future. However, we also have reason to believe that as domestic cable manufacturers increase their research and development efforts and produce qualified products in these technologies, they will be able to change the pattern that Chinese high-end cables are dominated by foreign forces to some extent. There will be Help China's 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 respond to market demand also respond to national calls. At present, a large number of production of wire and cable rubber, polyvinyl chloride, polyethylene and other polymer materials. In the production process produces a large number of toxic and harmful gases. Therefore, we must actively develop environmentally friendly materials, production of environmentally friendly wire and cable. Japan Fujikura and other cable companies in the development of environmentally friendly wire and cable, in order to monopolize the market, and actively promote the government enacted environmental protection wire and cable product standards. In recent years, the sales volume of environment-friendly wire and cable has rapidly expanded. Ordinary wire and cable and flame-retardant wire and cable can not compete with them. In addition, the wire and cable in the production process more than expected corner, can be recycled directly.
In addition, the aluminum alloy cables have been extremely hot in recent years. The main reason is that the cable industry is an industry with heavy materials and light industry, and the price of copper, which is the main raw material, is high, which has led to high cable production costs. To this end, the active introduction of foreign countries have been developed quite mature aluminum cable production technology, and hope to change the status of over-cable production. Moreover, the conductive properties of aluminum alloy cables and copper cables are comparable, its flexibility is better than the copper core cable, changing the past, poor mechanical strength pure aluminum cable, low fatigue resistance, joints prone to accidents And other shortcomings, to protect the cable overload and overheating in the case of long-term stability of the cable connection, but also make up for the traditional copper cable has a memory effect and high rebound performance defects, reducing line loss. In addition, aluminum cables have unparalleled economic and environmental advantages over traditional copper cables, from raw material production, processing and manufacturing to transportation, installation, operation and recycling. As of now, copper cables are the best alternative Product
In aluminum rare earth optimization, the current cable industry is a hot technology. As we all know, with continuous casting and rolling production of electrical aluminum rod in China has become quite popular, good performance. However, due to the equipment still stuck in the early 70s, there is not much technological innovation. To this end, we should actively promote our unique aluminum rare earth optimization treatment technology, and the use of some of the key special equipment and technology introduced to add aluminum zirconium alloy, the aluminum-fired furnace transformed into aluminum fuel or natural gas furnace, eliminating all aluminum melt Coal-fired furnace soot and flue gas emissions, and set the flue gas filter to purify flue gas to improve the quality of emissions and improve the yield, reduce costs, while the wire temperature from 70 ℃ to 150 ℃, carrying capacity increased 1.6 times .
