Product Overview<\/b><\/strong><\/h3>\n

The Series Filter<\/strong>\u00a0is a passive filtering device consisting of high-voltage capacitors and inductors in an LC filter configuration. It is designed to be used in high-voltage power systems to effectively filter harmonics, particularly in 10~12kV three-phase circuits. The filter works by leveraging the impedance characteristics of different frequency currents to filter out high-frequency harmonic currents, reducing interference to electrical equipment. This product is known for its high reliability and durability, having been successfully deployed in various high-load power applications for years.<\/p>\n
