Domestic high-voltage cable market is soaring

In recent years, the construction speed of UHV smart grids has been accelerating. In recent days, the State Grid Corporation of China also stated that it will further accelerate the construction of UHV smart grids with “two routes and two lines” in the second half of the year, and will guarantee the completion of the Suidong electricity transmission project by the end of September. In addition, the Hami South-Zhengzhou project will be put into operation at the end of the year; the Xiluodu-Zhexi project will be fully-bridged during the year; the Zhebei-Fuzhou project will be completed by the end of next year; and the Xinjiang-Northwest networked second channel and auxiliary power supply for the UHV AC-DC project will be actively promoted. Construction. Accelerate the restoration and reconstruction of power grids in the disaster-stricken areas of Sichuan Province; start the construction of Tibet's Qamdo and Sichuan networked projects; solidly promote the construction of pumped-storage power stations in Fengning, Hebei, and Dunhua, Jilin; Fujian Xianyou Pumped-storage Power Station will be put into operation within the year; do a good job in the reconstruction of the Fengman Dam...

It can be seen that, with the acceleration of the construction of UHV smart grids, the market prospect of high-voltage cable insulation materials is broad. At present, high-voltage cable insulation materials are mainly imported from abroad. According to the research report of U.S. industrial market research company Fridonia, the demand for insulated cables in the U.S. will greatly increase. In the next four years, market demand will reach nearly 180 billion yuan. yuan. In addition, the insulation cable manufacturers are constantly optimizing and improving the technology and quality of their products to meet domestic and export needs.

Faced with the huge domestic demand and the tremendous pressure from abroad, the development prospects of domestic high-voltage cables are indispensable, but the first step is to realize the localization of high-voltage cable insulation materials. At present, the state encourages the localization of high-voltage cable insulation materials to be vigorously promoted, and gives certain support to the policy. If a breakthrough can be achieved in the production of high-voltage cable insulation materials, it will be of great significance to the industry and to the country and society. .

First of all, if localization of high-voltage cable insulation materials is achieved, it will effectively break the monopoly of foreign industries and promote the transition of domestic cable manufacturers from low-end market competition to high-end market competition. This is an extremely important entrance.

Secondly, due to the fact that domestic high-voltage cable insulation materials are almost completely dependent on exports, they lack the right to speak in terms of prices, which results in high prices of high-voltage cable products. If domestically successful development and production of elegant cable insulation materials, then the The reduction of high-voltage cable prices in the land is a good thing for Guo Yumin.

Finally, the localization of high-voltage cable insulation materials is a direct performance of domestic cable companies, technological innovation, product upgrades, and it is a direct reflection of the “bigger and stronger” cable industry in China. From a certain point of view, if China's cable manufacturers successfully develop qualified high-voltage cable insulation, it will change the embarrassing situation of high output value and poor technology in the domestic cable industry.

In fact, China is not a company that does not produce high-voltage cable insulation. However, the vast majority of production companies have always competed on low-grade and low-tech products. The production of high-voltage cable insulation materials is based on the selection of raw materials, production processes, and purification processes. The production equipment is different from the production of other insulation materials, and it contains technological innovations in terms of production equipment, production technology, and product quality control. It is a qualitative leap in product application and product quality control. The zero breakthrough in localization of high-voltage cable insulation materials will undoubtedly promote the upgrading of the domestic cable industry.

In addition, from the upstream market point of view, domestic research and development, production of high-quality high-voltage cable insulation material also has inherent advantages. In particular, with the extension of the industrial chain, as an upstream petrochemical enterprise of cable materials, it has long been recognized that cable materials, especially high-voltage cable insulation materials, have a broad market, and have a huge space for development. Therefore, major domestic petrochemical companies have turned their attention to the cable material industry. It can be said that this is a very good phenomenon and development trend. It is very powerful for the development and localization of high-voltage cable materials and special cable materials.

Of course, as petrochemical enterprises should also fully realize that the resin material as a cable material has its own particularity and has a relatively high material quality requirement. Therefore, petrochemical enterprises should consciously establish special production equipment and process parameters according to the requirements of cable materials. Processes, etc., in order to produce the resin to meet the requirements of cable materials, only in this way can control the quality of cable products, so that domestic high-voltage cable materials and other materials, the healthy development.

However, there are still many obstacles in the research and development of insulating materials for high-voltage cables in accordance with the current characteristics of the current low concentration of the domestic cable industry and the lack of independent research and development capabilities. The most significant bottlenecks are: large input costs, high technical difficulty, low user acceptance, and insufficient close cooperation with raw material suppliers. If these four aspects are solved, it will be extremely important to support and help domestic cable manufacturers to develop and produce high-quality high-voltage cable insulation.

This also requires the current domestic capable, well-known large-scale cable material production enterprises, should continue to increase research and development costs, and strive to develop domestic high-voltage cable insulation materials. Actively organize technical personnel to tackle problems, adopt the methods of production, study and research, give full play to their advantages, and solve production process problems. In addition, it actively cooperates with raw material upstream enterprises to produce resin materials that meet the requirements, and solves the problem of localization of high-voltage cable insulation materials from the industrial chain.

The government should also give support and help from policies and funds. Of course, the most important thing is that domestic high-voltage cable users, especially power users, should break the “colored glasses” for domestic cable quality, actively support domestic production, and use domestically produced cross-linked materials to produce high-voltage cables. As a result, not only has it supported the development of the domestic cable industry, it has saved the company's procurement costs and has also contributed to the national industry.

In accordance with the characteristics of low entry barriers in the domestic cable industry, to effectively prevent some small and medium-sized enterprises that are not productive, after they smelled the machine, they swarmed into the high voltage cable insulation material market and brought disorderly competition to the market. Therefore, the country should The first step is to introduce the policy and effectively curb it. It can be said that this is very important, because high voltage cable insulation material is different from medium and low voltage cable insulation material, if cable material quality problems affect the quality of cable products, and then affect the power quality of the power grid, there are quality accidents, great harm, and damage Localization of high voltage cable insulation.

In addition, high-voltage cable procurement companies should specify the domestic raw material users in bidding, so as to effectively protect the brand raw material production enterprises, but also conducive to cable product quality control.

Undoubtedly, the domestic high-voltage cable market is huge and the market has a promising future. According to relevant department surveys, the current domestic high-voltage cable insulation material usage rate growth rate remained at 20%. According to the calculation of the length and cross-section of high-voltage cables used in recent years, the demand for high-voltage cross-linked cable materials is about 50,000 tons this year.

To this end, domestic cable manufacturers should vigorously develop domestic high-voltage cable insulation materials, first to seize the market, change imports to domestic, change domestic to export, change the low-end market competition for high-end market competition, and contribute to the revitalization of high-voltage cable national industries. In addition, the government is currently vigorously advocating and supporting the transformation of the domestic cable industry from "Made in China" to "Created in China," adding that the current construction of ultra-high voltage smart grids continues to advance, bringing great market and business opportunities to cable manufacturers. Domestic cable manufacturers, especially large and powerful ones, should increase R&D costs and move forward for a more brilliant future.
