Demand for high-voltage, ultra-high voltage cross-linked cables

With the implementation of national policies such as the “Eleventh Five-Year Development Plan Proposal for the Wire and Cable Industry” and the “Adjustment and Revitalization Plan for the Equipment Manufacturing Industry”, the country has the supporting functions of electric power and telecommunications as the pillar industries of the national economy for wire and cable. The industry is paying more and more attention. Experts predict that the annual demand for high-voltage and ultra-high voltage cross-linked cables of 110 kV and above in China will increase with the "Eleventh Five-Year Plan for Development of Wire and Cable Industry" and "Equipment Manufacturing In the implementation of national policies such as the Adjustment and Revitalization Plan, the state is paying more and more attention to wires and cables, an industry that shoulders the supporting functions of the power and communication industries of the two major national economy pillars. Experts predict that China will have 110 kV by 2020. The annual growth rate of the above high-voltage, ultra-high voltage cross-linked cables is about 14%. It will reach 13,000 kilometers in 2010, 26,000 kilometers in 2015, and 50,000 kilometers in 2020.

Thanks to the rapid development of China's economy, the wire and cable industry has generally maintained a good momentum of growth in recent years. In particular, China has introduced a series of economic stimulus policies to expand domestic demand and bring rare opportunities for the wire and cable industry.

According to the data, China's economic development and power construction have great demand for 110 kV and above high-voltage cross-linked cables, and its growth rate has been 20% to 25% in recent years. According to the forecast of experts, due to the impact of the financial crisis on the wire and cable industry, the growth will be somewhat slower thereafter. However, the annual growth rate of high-voltage, ultra-high voltage cross-linked cables of 110 kV and above in China before 2020 is objectively predicted to be approximately 14%. It is expected to reach 13,000 km in 2010, 26,000 km in 2015, and 50,000 km in 2020.

According to forecasts, the market demand for 220 kV cables is also very strong, and it is expected to reach 1,600 km in 2010, 3,700 km in 2015, and 7000 km in 2020; the market demand for 500 kV cables is expected to be: 400 kilometers, 870 kilometers in 2015 and 1,700 kilometers in 2020.



According to the latest statistics, China currently has a total of nearly 400 lines of 35 kV CCV (catenary) medium and low voltage cables; nearly 70 lines of 110 kV and above cross-linked power cables (including those under construction), among which VCV (vertical) production lines There are nearly 50 CCV (catenary) production lines with an annual production capacity of approximately 21,000 kilometers (calculated as 110 kV cables).



According to the national energy plan, the construction and renovation of the new round of large power grids and urban and rural power grids will in turn bring tremendous business opportunities to the cable manufacturing industry. During the “Eleventh Five-Year Plan” period, the State Grid Corporation’s total investment reached 850 billion yuan, and the country’s total investment exceeded 1 trillion yuan. Experts predict that by 2020, China's UHV and cross-regional grid transmission capacity will be 210 million kW, of which 800 kV DC power grid is about 56 million kW, and another about 150 million kW by the AC grid. By 2020, the market demand for cables will reach 406 billion yuan.

First, with the rapid development of new energy industries, wind power, nuclear power and other clean energy have ushered in an unprecedented construction cycle. The market size of special cables in China is 40 billion to 50 billion yuan per year, accounting for 20% of the total domestic cable market. 30%, while the current high-end cables required by China are almost all dependent on imports. The second is that the copper twisted pair cable used in communications will continue to be the protagonist of the broadband subscriber line in the next 10 years. It is expected that the second climax of telephone cable sales will occur in a few years, and the annual sales volume may recover to 70 million to 85 million pairs of kilometers, indicating a steady increase. Third, although the domestic supply of electronic wire rods is in excess of demand in macro terms, it cannot meet the needs of the color TV industry in terms of variety, specifications and special performance. For example, ultra-fine enameled wire, there are more than 10 domestic manufacturers, but due to various reasons, about one-third still need to rely on imports. Self-adhesive enameled wire, China's varieties and performance and the international advanced level there is a big gap, some high-performance and high heat-resistant grades of the product still need to import, these products need to be realized in the domestic. Fourth, the power cable accounts for 25% of the total output value of the cable. The annual output value is nearly 40 billion yuan, which is a big market. And the market capacity of power cables is still growing at an annual rate of 14%.

The involvement of foreign wire and cable giants has added even more uncertainty and uncertainty to China's uncertain cable manufacturing industry. However, we should also see its positive side. The foreign wire and cable companies entered the Chinese market and formed the fact that the Chinese market is internationalized. Foreign wire and cable companies have brought in advanced capital management and technology, and also brought advanced management concepts and management culture, which are beneficial to domestic wire and cable companies for learning and learning. To establish an international perspective and implement an internationalization strategy, "If domestic cable companies want to survive, they must increase their awareness of the crisis and improve their competitiveness.
