Product Description
The RVR-1 single-phase step voltage regulator is an advanced tap-changing autotransformer designed for precise voltage regulation on 11kV overhead distribution lines. Manufactured exclusively in China, it automatically adjusts line voltage within a range of ±10% in 32 fine steps (approx. 5/8% per step), ensuring stable power supply under varying load conditions. Suitable for 50/60Hz systems, it offers flexible configurations for pole-mounted, pad-mounted, or substation installations.
