The construction of smart grids drives an 18% annual increase in the demand for core components of reactive power compensation devices

The demand for energy efficiency improvement in the industrial sector is driving steady growth in the power capacitor market, particularly low-voltage shunt capacitors used for reactive power compensation and filtering devices. Industry statistics show that shipments of this category increased by 22% year-on-year in 2023, primarily benefiting from the accelerated automation transformation of the manufacturing industry and the large-scale construction of new infrastructure such as data centers.

Technological development exhibits a clear trend: firstly, environmental protection, where a new generation of products adopts biodegradable insulating oil to replace traditional mineral oil, reducing flammability by 70%; secondly, intelligence, with built-in sensors capable of real-time monitoring of key parameters such as temperature and current, and outputting health status data through digital interfaces; thirdly, modularization, with standard unit design supporting rapid combination and expansion, reducing maintenance time by 60%.

In terms of product performance, by optimizing the internal fuse design and controlling the field strength at the electrode edge, the expected lifespan of the product under 1.5 times overvoltage has been extended to 200,000 hours. The newly developed series of products dedicated to harmonic filtering exhibit a temperature rise 15K lower than conventional products under operating conditions containing 30% third-order harmonics, making them particularly suitable for industrial environments with dense frequency converters.

In terms of production line upgrading, the fully automated winding equipment, coupled with an online capacitance measurement system, achieves the manufacture of one core every 3 seconds with a precision controlled within ±0.5%. The vacuum impregnation process employs multi-level step pressure control to ensure that the insulation medium filling rate reaches over 99.9%. According to industry forecasts, with the global construction of smart grids and the advancement of Industry 4.0, the demand for related products will maintain double-digit growth in the next five years.
