Product descriptions from the supplier
Product Description
As a pioneer and the first source factory in China's voltage regulator industry, we have been deeply rooted in the sector for decades, accumulating profound technical expertise. Leveraging top-tier R&D capabilities and a mature manufacturing system, our products have gained widespread market trust with reliability and performance that far exceed industry standards.
The RVR-1 is a high-performance single-phase automatic voltage regulator for utility grids and industrial systems. It merges oil-immersed transformer reliability with advanced smart digital control, delivering precise, stable voltage regulation in harsh environments (remote rural grids, industrial parks, heavy-load facilities).
Its oil-immersed insulation ensures thermal stability, moisture resistance, and dielectric strength for long-term reliable operation in extreme conditions. Equipped with an intelligent digital control module, it offers real-time monitoring, automatic precision adjustment (multi-step tap switching), and remote communication (GPRS/GSM/Bluetooth) for easy configuration, fault diagnosis, and reduced on-site maintenance.
Ideal for mitigating voltage fluctuations from grid instability, load changes, or long-distance transmission, it safeguards sensitive equipment, improves power quality, and minimizes downtime—providing consistent, efficient power support.

The regulator uses multi-step tap switching (e.g., 32-step/16-step) and an intelligent control module to real-time monitor grid voltage fluctuations. It automatically adjusts tap positions to stabilize output voltage within a ±10% (or ±20%) range (0.625%/2.5% per step), compensating for line drops/load changes. Ideal for overhead utility/industrial systems needing consistent voltage.
Designed for 50Hz/60Hz single-phase grids (6kV-34.5kV), it’s pole-mounted for easy overhead line deployment—perfect for rural power networks, industrial parks, and remote load centers. It withstands harsh environments (extreme temps/humidity) and supports custom voltage ratings, fitting diverse utility/industrial precise regulation needs.
