In the world, China's total output value of wire and cable has surpassed that of the United States and has become the world's largest wire and cable producer. With the rapid development of China's wire and cable industry, the number of newly added companies has continued to rise, and the industry’s overall technological level has been greatly improved. Although the wire and cable industry is a basic industry, it currently occupies 1/4 of the output value of China's electrical industry, and is called the "artery" and "nervous" of the national economy. As the second largest industry next to automobiles, its product variety satisfaction rate and domestic market share exceed 90%.
Since the reform and opening up, the huge production capacity formed by the Chinese cable manufacturing industry has made the world impressive. In 2009, the Chinese government actively stimulated domestic demand and increased investment in the construction and transformation of urban and rural power grids. The domestic wire and cable industry ushered in new opportunities, and there is still great potential for development in the future.
From the perspective of China’s rapid economic development and historical growth, in recent years, China’s cable demand has increased by 15% every year, but there are fewer cable manufacturers on the scale. At the same time, ultra-clean cross-linked polyethylene insulation used for high-voltage cables has not been produced so far in China, and many other special wire and cable materials are still imported.
Breakthroughs in wire and cable companies where China's wire and cable industry product structure has been adjusted to a good direction. With the EU's promulgation of the ROHS Directive, the development and large-scale adoption of eco-friendly wire and cable has become an international trend. With the increasing awareness of environmental protection, the application of halogen-free low-smoke cross-linked polyolefin insulated wire and cable will gradually expand.
At present, the application of fire-retardant and fire-resistant cables at home and abroad has expanded to many fields. For example, mining, general purpose rubber-jacketed cables, elevator cables, and cables for household appliances all have different degrees of flame-retardant requirements. China's Beijing, Shanghai and other key cities have adopted halogen-free low-smoke cross-linked polyolefin insulated wire and cable.
Focusing on technological innovation and focusing on the sustainable use of raw materials, only by reducing environmental pollution can we effectively increase the utilization rate of resources and reduce costs. It can be predicted that which company will do well in this area and become the leader in the wire and cable industry will be just around the corner.
The wire and cable companies announced that the first round of offshore tenders for the 1 million kilowatt offshore wind power concession project in China was announced through the new energy industry, indicating that offshore wind power has entered the stage of scale development. The construction of offshore wind farms is currently an important direction for the development of international new energy, and will also be the direction for the development of China's wind power industry. For submarine cables, their application in offshore wind power generation and transmission has a broad market prospect.
As the submarine cable project is recognized as a complex and difficult large-scale project in the world, from the environmental exploration, marine physics investigation, as well as the design, manufacture, and installation of cables, complex technologies have been applied, so that the manufacturers of submarine cable are still in the world. many. Most of the submarine power cables used in China are currently imported.
At present, submarine cables cannot be compared with foreign counterparts at the technical level. In particular, photovoltaic composite submarine cables and submarine cross-connected cable technologies that produce voltage classes of 220 kilovolts and above are currently under development at home and are used in some deep sea and oil platforms. Domestic high-tech products are only at the stage of understanding; some special cable technologies know very little, and we still have a long way to go.
China has a great demand for submarine cables. If cable manufacturers can seize opportunities and independently innovate and use their favorable conditions to develop advantageous submarine cable products, they will not only have a place in the domestic market, but also have the potential to fully utilize domestic cables. Cost advantage, enter the international market.
At present, domestic wire and cable companies are facing a period of rapid development, which is closely related to the development of China's economy, society, national defense, and energy.
According to the national plan, China will speed up the construction of new countryside and the process of urbanization in rural areas. This requires considerable power support, which also requires a lot of wire and cable usage.
Not long ago, the State Grid Corporation of China (hereinafter referred to as the State Grid) announced that by 2015 it will build a UHV power grid in North China, East China and Central China (“Sanhuaâ€), forming a “three vertical and three horizontal and one ring networkâ€. On the same day, State Grid announced that the world's highest 1000kV Jindongnan-Nanyang-Jingmen UHV AC pilot demonstration project has passed national acceptance, which indicates that UHV is no longer a "test" and "demonstration" phase. The process of approval and construction of the project is expected to accelerate.
In the next five years, the investment amount of UHV will increase substantially. The goal of the State Grid is to complete the construction of the “Three Chinas†UHV power grid by 2020, the Northeast UHV power grid, and the Northwest 750 kilovolt power grid as the delivery end, linking major coal and electric power bases, large hydropower bases, and large nuclear power bases. Large renewable energy bases, coordinated development of smart grids at all levels of the grid.
