There is a huge market space for UHV capacitor films. Da Southeast is a representative domestic manufacturer.

UHV capacitor film is a film used as a dielectric material for thin film UHV capacitors. UHV capacitors are an indispensable and important device in UHV power transmission systems. UHV capacitor film is the key core dielectric material of UHV capacitors, and its cost accounts for more than 70%. As the construction scale of my country’s UHV transmission projects continues to expand, the demand for UHV capacitors in my country continues to grow, driving the UHV capacitor film market to continue to rise.

In UHV transmission systems, UHV capacitors can be used in UHV AC and DC transmission lines. Their main functions are filtering, voltage stabilization, phase shifting, etc., which can improve the transmission capacity and operational stability of the power grid and can be used in power transmission, transformation, and distribution. In various aspects such as electricity. The scale of new energy power generation such as photovoltaics and wind power in my country continues to expand, the demand for west-to-east power transmission and north-to-south power transmission continues to grow, and the number of UHV transmission projects continues to increase. During the “14th Five-Year Plan” period, the State Grid plans to build “24 transmission lines” A total of 38 UHV projects in 14 years will drive the demand for UHV capacitors to continue to rise, which will benefit the development of the UHV capacitor film industry.

In my country’s UHV capacitor film market, Great Southeast is one of the representative companies. The UHV capacitor film produced by its subsidiary Great Southeast Wanxiang Technology is included in the national UHV power construction catalog and has been recognized by the national UHV power grid capacitor manufacturer. The Changji-Guquan ±1100 kV UHV DC transmission line project started in 2016 uses the UHV capacitor film produced by Dadongnan. Since then, Great Southeast UHV capacitor film has obtained the right to supply in many UHV major projects of the State Grid and China Southern Power Grid.

In the first half of 2021, Dadongnan’s operating income was approximately 787 million yuan, a year-on-year increase of 19.49%; the net profit attributable to shareholders of the listed company was approximately 93.19 million yuan, a year-on-year increase of 132.85%. Dadongnan is a professional film manufacturer in my country, and UHV capacitor film is one of its four core technology products. Great Southeast is one of the few companies in my country with UHV capacitor film production capabilities. In 2020, its share will reach about 30% in my country’s UHV capacitor film market, and it is highly competitive.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on UHV Capacitor Film Industry 2022-2026” released by the Industrial Research Center, Compared with other thin film products such as optical films, UHV capacitive film product standards have extremely high requirements, such as film crystallinity, heat resistance, thickness consistency, etc., and strict requirements on the technical strength of enterprises. In addition, UHV capacitor films are used in UHV transmission systems. In order to ensure the stability of UHV power grid operations, the two major manufacturers, State Grid and China Southern Power Grid, strictly review the quality of related electrical equipment. UHV capacitor films require a long certification time. The requirements for enterprise qualifications and strength are high.

Industry analysts People said that since 2012, my country’s capacitor film production capacity has expanded rapidly and is currently in a stage of overcapacity, with fierce market competition. Among capacitor film products, UHV capacitor film is a high-tech, high-value-added product with a small number of manufacturing companies and gentle market competition. Capacitive film companies with strong capabilities can transform and upgrade in this field. However, due to the high concentration of my country’s UHV capacitor film market at this stage, it is difficult for companies that are weaker and unable to compete with existing companies to enter.
