RVR-1 Single-Phase Voltage Regulator (6-34.5kV): IEEE/ANSI compliant, 32-step on-load regulation. Fully sealed, maintenance-free, 1M-cycle lifespan with overload/undervoltage protection—reliable for stable power distribution.
ROCKWILL 6kV to 34.5kV Single Phase Automatic Voltage Regulator is pole-mounted single-phase voltage regulation equipment, designed for overhead distribution feeders. It covers system voltage range from 6kV up to 34.5kV, with on-load tap changing function to maintain stable output voltage under variable load and line drop conditions. The unit integrates single-phase transformer body, on-load tap changer, voltage sensing and intelligent control unit. It is tropicalised with anti-corrosion and UV resistant enclosure, suitable for outdoor harsh environment. Multiple tap positions with automatic voltage adjustment, local/remote monitoring and communication function are available. Type tests comply with relevant IEC and ANSI standards, widely used for long rural overhead distribution circuits to mitigate voltage drop issues.
