In recent years, the domestic power capacitor industry has developed rapidly. The quality and quantity of products have been greatly improved, and a considerable number of advantageous companies have begun to gain ground in the international market and have achieved good results. With the rapid development of the power industry, technological progress, and the strengthening of reactive power compensation and energy-saving loss management, power capacitor manufacturers have encountered unprecedented opportunities for development, which has rapidly expanded the market for power capacitors, and has also triggered many areas of power capacitors A large amount is required.
