【Summary Description 】 With the implementation of national policies such as the "11th Five-Year Plan for the Development of Wire and Cable Industry" and the "Plan for the Adjustment and Revitalization of Equipment Manufacturing Industry"

With the implementation of national policies such as the "11th Five-Year Plan for the Development of the Wire and Cable Industry" and the "Plan for the Adjustment and Revitalization of the Equipment Manufacturing Industry", the government is attaching more and more importance to the wire and cable industry, which shoulders the supporting functions of the two pillar industries of the national economy, power and communication, experts predicted. The annual demand growth rate of 110 kv and above high-voltage and ultra-high-voltage cross-linked cables will be about 14% before 2020. It is expected to reach 13,000 km in 2010, 26,000 km in 2015 and 50,000 km in 2020.
Thanks to the rapid development of Chinese economy, the cable industry has maintained a good growth momentum in recent years, especially a series of economic stimulus policies to expand domestic demand, which brings rare opportunities for the cable industry.
Data show that economic development and electric power construction of our country for 110 kV and above high voltage cross-linked cable demand is great, the proportion of its growth in recent years is 20%~25%. According to experts, due to the impact of the financial crisis on the wire and cable industry, the growth will slow down somewhat, but it is objectively predicted that the annual growth rate of 110 kv and above high-voltage and ultra-high-voltage cross-linked cables will be about 14% before 2020. It is expected to reach 13,000 km in 2010, 26,000 km in 2015 and 50,000 km in 2020.
The market demand for 220 kV cables is also expected to be strong, reaching 1,600 km in 2010, 3,700 km in 2015 and 7,000 km in 2020. The estimated market demand for 500 kV cables is 400 km in 2010, 870 km in 2015, and 1,700 km in 2020.
According to the latest statistics, our country has 35 kV CCV(catenary type) medium and low voltage cable production lines nearly 400; There are nearly 70 cross-linked power cable production lines of 110 kV or above (including those under construction), including nearly 50 VCV(vertical) lines and about 20 CCV(catenary) lines, with an annual production capacity of about 21,000 kilometers (calculated by 110 kV cable).
According to the national energy planning, a new round of construction and transformation of large power grid and urban and rural power grid will bring huge business opportunities to the cable manufacturing industry. The total investment of the State Grid Corporation during the 11th Five-Year Plan period reached about 850 billion yuan, and the total investment of the whole country exceeded 1 trillion yuan. Experts estimate that by 2020, the transmission capacity of China's UHV and trans-regional power grids will be 210 million kW, of which 800kV DC power grids will be about 56 million kW, and another 150 million kW will be made up of AC power grids. By 2020, the market demand for cables will reach 406 billion yuan.
First, with the rapid development of the new energy industry, wind power, nuclear power and other clean energy ushered in an unprecedented construction cycle, the market size of our special cable is 40 billion to 50 billion yuan a year, accounting for 20% to 30% of the total scale of the domestic cable market, and the current China needs high-grade cables almost all rely on imports. The second is that the copper cable used for communication will still be the main role of broadband subscriber lines in the next 10 years. Telephone cable sales are expected to see a second boom in a few years, and annual sales are expected to recover to 70 million to 85 million km, showing a steady but rising trend. Third, although the domestic market of electronic wire oversupply in the macro, but in the variety, specifications and special performance can not meet the needs of the color TV industry. For example, there are more than 10 domestic manufacturers of ultrafine enamelled wire, but for various reasons, about one-third of them still need to rely on imports. Self-adhesive enamelled wire, our country still has a relatively large gap with international advanced level in varieties and performance, and some high performance and high heat resistant grade products still need to be imported, and these products need to be realized in China. Fourth, power cable accounts for 25% of the total output value of cable, with an annual output value of nearly 40 billion yuan, which is a large market. And the market for power cables is growing at 14% a year.
The intervention of foreign cable industry giants adds greater variables and uncertainties to the uncertain prospect of China's cable manufacturing industry. However, we should also look at the positive side. Foreign cable enterprises enter the Chinese market, the formation of the fact that the Chinese market internationalization, foreign cable enterprises bring capital and technology at the same time, but also bring advanced management philosophy and management culture, conducive to domestic cable enterprises to learn and learn from, establish an international perspective, the implementation of international strategy, "domestic cable enterprises to survive, it is necessary to enhance the awareness of crisis, improve competitiveness.
