China's wire and cable industry chain is relatively mature, which is divided into upstream raw material industry, different types of cable manufacturing industry in the middle and downstream application fields. The upstream raw material industry is relatively mature, which provides a good foundation for the development of wire and cable industry. The concentration of wire and cable manufacturing industry in the middle reaches is relatively low, and there is a big gap between developed countries, most of which are small and medium-sized enterprises. The development prospects of downstream applications are good, and the development goals of various industries put forward new requirements for the output, product types and quality of wires and cables.
1.Analysis of Wire and Cable Industry Chain
Wires and cables are the basic products for transmitting electric (magnetic) energy, transmitting information, realizing electromagnetic energy conversion and forming automatic control lines. There is no strict difference between wires and cables. Generalized wires and cables can also be called cables. Usually, the products with simple structure, no outer sheath and smaller outer diameter are called wires, and the products with complex structure, strong sealing outer sheath and larger outer diameter are called cables. The main structure of the cable is "conductor + insulation", and the main structure of the cable is "conductor + insulation + sheath".
At present, the industry chain of wire and cable industry in China is relatively mature. The upstream industry mainly provides the basic material industries for manufacturing raw materials of wire and cable products, such as copper, aluminium and its alloys; the rubber industry for manufacturing cross-linked insulating sheaths and sheaths; the polyethylene and polyvinyl chloride chemical industry; and the middle industry includes power cables, communication and so on. Cables for telecommunication cables, electrical equipment and other types of cables, such as bare wires, winding wires, etc., are manufactured and manufactured by cable manufacturers. The downstream industries are mainly those with demand for wires and cables, such as construction machinery, telecommunications, electric power and construction industries.
2.Upstream industries are relatively mature
The upstream of wire and cable industry is mainly raw material industry: copper-aluminium alloy, rubber sleeve and polyethylene, polyvinyl chloride chemical raw materials, etc. Because the above raw material industry has developed for a long time, the technology level is relatively mature, and there are many companies in the industry, it can provide a good basis for the development of the wire and cable industry. The main companies in the copper and aluminum alloy industry are Tongling Nonferrous Metals, Jiangxi Copper Industry, Yunnan Aluminum Co., Ltd. The main companies in the rubber industry are Hainan Rubber, Black Cat Carbon Black and Hongda New Materials, etc. The chemical industry is mainly the production enterprises of polyethylene and polyvinyl chloride, and the representative companies are Golden Fair Technology, Prit and Jinlu Group.
3.The downstream application prospects are good.
The downstream application fields of wire and cable industry are mainly electric power industry, communication industry, engineering machinery, petrochemical industry and so on. Since the 13th Five-Year Plan, most of the downstream application fields of the wire and cable industry have put forward the development goal of 2020. In the future, more demands will be put forward on the output, types and quality of wire and cable products, so as to promote the rapid development of China's wire and cable industry.
