In the production of wire and cable , because the cost of raw materials accounts for more than 80% of the production cost, and copper, aluminum, steel core, rubber, plastic and sheath materials are the mainstay of raw material costs, which requires wire and cable enterprises. Work hard to design distinctive products, save raw materials, and develop new environmentally friendly materials. Therefore, the following measures must be considered in the future to create a circular economy in the wire and cable industry:
First, eliminate the cold rolling mill and the black copper rod. The production process of rolling the 芰8 black copper rod by cold rolling mill is backward, and its black copper rod has high oxide content, low electrical conductivity, poor performance, small tensile force ratio, consumables, energy consumption and serious pollution. Eliminated.
Secondly, actively promote the optimization technology of aluminum rare earth. The production of electrical aluminum rods by continuous casting and rolling process has been quite popular in China, and the performance is also good, but the equipment still stays at the development level in the early 1970s, and there is not much innovation in technology. It is necessary to actively promote the unique aluminum rare earth optimization treatment technology in China. And use some of the key special equipment and technology introduced to add aluminum-zirconium alloy, transform the molten aluminum coal-fired furnace into molten aluminum fuel or natural gas furnace, all eliminate the emission of coal-fired soot and flue gas from the molten aluminum coal-fired furnace, and set the flue gas The filter device purifies the flue gas, improves the discharge quality, improves the yield, reduces the cost, and increases the working temperature of the wire from 70 ° C to 150 ° C, and the current carrying capacity is increased by 1.6 times.

Third, actively introduce technology and independently develop and develop special equipment for wire and cable with excellent performance. At present, the key production equipment of wire and cable leading products is still far from the advanced equipment of foreign countries. The technical level is still very large, mainly in the low productivity, low automation, high energy consumption, poor reliability, and can not meet the development of the industry. Need, digestion and absorption is seriously delayed. The technical level, performance and reliability of wire and cable special equipment have incalculable benefits for improving wire and cable product quality, production efficiency and material utilization. It is necessary to actively introduce technology and independently develop and develop high-performance wire and cable equipment with high performance, to create a circular economy service for the wire and cable industry. Finally, we will actively develop environmentally-friendly wire and cable products and strengthen the recycling of waste wire and cable products. At present, a large number of polymer materials such as rubber, polyvinyl chloride and polyethylene are used in the production of wire and cable products. The telephone generates a large amount of toxic and harmful gases during the production of wire and cable products. Therefore, we must actively develop environmentally-friendly wire and cable raw materials and produce environmentally friendly wire and cable. After the development of environmentally-friendly wire and cable products, cable companies such as Fujikura of Japan actively promoted the government's environmentally-friendly wire and cable product standards in order to monopolize the market. In recent years, the sales share of environmentally-friendly wire and cable products has expanded dramatically, and ordinary wire and cable and flame-retardant wire and cable cannot compete with it. The corner residuals generated during the production of wire and cable can be directly recycled. It is recommended to set up a professional "polyvinyl chloride" waste recycling treatment plant, fixed-point processing, and use it for other purposes to avoid secondary pollution.
