Product Overview
The Pole-Mounted Reactive Power Compensation Device (also known as a line reactive power compensation device) is a dedicated complete set of compensation equipment specifically designed for 6kV and 10kV high voltage distribution lines. Its core functions are to compensate for reactive power losses along the line and balance grid reactive power. It can effectively improve line power factor, reduce line losses, stabilize line voltage, and extend the service life of power transmission and transformation equipment. It is a key supporting device for energy saving, loss reduction, and stable operation of high voltage lines.
The product is primarily available in outdoor pole-mounted and floor-standing configurations, designed to suit outdoor installation scenarios for high voltage lines. It is factory pre-assembled and tested, strictly adhering to national and industry standards. High-quality components resistant to harsh outdoor environments are used. It features a compact structure, wind and rain resistance, reliable operation, and convenient maintenance. It is widely used in high voltage distribution lines, rural power grids, industrial park transmission lines, and distribution network renovation projects.
