In July of this year, the national government released the "China Railway Network Plan". According to the plan, by 2025, the scale of China's railway network will reach about 175000 kilometers, including about 38000 kilometers of high-speed railways. By 2030, the scale of the high-speed railway network will reach about 45000 kilometers, connecting major provincial capitals and other large and medium-sized cities with a population of over 500000. The rapid development of high-speed rail in our country is building an increasingly dense railway network. As an important carrier of high-speed railway power transmission, the overhead contact system has become the main artery and lifeline of rail transit. The rapid development of high-speed rail will bring unlimited business opportunities to the cable industry.

To ensure the safe and fast operation of high-speed railways, the quality and efficiency of their transmission cables must also be guaranteed. In high-speed operation, a strong current supply requires high-speed rail transmission lines to achieve safe and reliable current transmission in a short period of time. Butcontrol cableQuite advantageous. This is also one of the reasons why copper cables are mainly used for high-speed railway transmission lines at present.

In addition, copper cables have the ability to resist tension, shrinkage, creep, and fracture, as well as excellent flexibility, corrosion resistance, and ductility, which can meet the stable and reliable operation of high-speed railways in various climatic environments, which aluminum cables cannot achieve. In the next few years, the development speed of China's wire and cable industry will be higher than that of the national economy, expected to reach more than 10%. Especially for power lines and ADSS cables, the annual growth rate can reach 15%, showing a rapid momentum.

In recent years, due to the acceleration of China's power grid construction and the successive investment in ultra-high voltage projects, a huge market has been created for the wire and cable industry. In the past 15 years,wire and cableThe industry has an average annual growth rate of over 15%. At present, the total industrial output value of the industry exceeds 400 billion yuan, surpassing the United States and becoming the world's largest producer of wires and cables. At present, China's wire and cable industry has formed a huge production capacity based on a large amount of technology introduction, digestion and absorption, and independent research and development. The cable material and cable equipment manufacturing industry that is matched with it has also initially formed a relatively complete supporting system. It mainly presents that large enterprises have obvious advantages in market competitiveness and strong profitability; Small and medium-sized enterprises have good asset operation capabilities; The market-oriented operation mechanism of private enterprises is flexible and rapidly developing, especially the prominent advantages of wire and cable manufacturing enterprises in economically developed coastal areas. In terms of assets, the state-owned economy currently accounts for only 15%, while the three capital enterprises account for nearly 25%, and the private economy accounts for over 60%.

Among the top companies in the wire and cable industry in terms of sales revenue, the vast majority are private enterprises. The East China region is the most important manufacturing area for the wire and cable industry, accounting for 50% of the country's assets and output value, generating 60% of sales revenue, and winning 70% of the industry's profits. In recent years, the development of control cables has been very rapid, and its development speed has significantly exceeded that of the wire and cable industry. Control cables refer to cables with a standard of GB/T9330, and their insulated cores are generally black and white. Compared with power cables mainly used for power transmission, the cross-section of control cables generally does not exceed 10 square meters. As control cables for transmitting control signals, they are generally 61 cores, but can also be changed according to user requirements. In the wire and cable industry, state-owned enterprises no longer dominate the industry.
