Smart Low voltage power capacitor

Low voltage intelligent power capacitor is used in low voltage distribution network, such as construction, industrial construction, city power grids, rural power grids, etc. Its can stable voltage, reduce the line loss, improve power factor and energy conservation. Changed the traditional reactive compensation device which is bulky and heavy structural model, and so more cost savings, easy to maintain.
