The HD series power capacitors are mainly used for reactive power compensation in power systems, which can effectively improve power factor and reduce reactive power loss. They are particularly useful for power factor correction and voltage waveform improvement of low-voltage equipment. The product is made of metalized polypropylene film and wrapped in special steel plates treated with sandblasting and rust prevention. It has a dry structure and mechanical explosion-proof design, and has high reliability and safety.
