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 24kV single-phase pole-mounted 32-step automatic voltage regulator, based on advanced on-load voltage regulation technology, enables precise 32-step voltage adjustment. Equipped with an intelligent monitoring module, it can capture subtle voltage fluctuations in the distribution network in real time, respond quickly, and automatically switch voltage regulation taps to adapt to complex and changeable distribution network conditions.
Designed for pole mounting, it is compatible with different pole types and installation environments, eliminating the need for additional complex foundations and greatly simplifying the deployment process. With fully automated operation—from voltage detection and tap switching to voltage regulation execution—no manual intervention is required, which not only improves operation and maintenance efficiency but also avoids human operation errors.
It stably outputs 24kV single-phase voltage, effectively suppressing voltage deviations, flicker, and other issues, providing continuous and reliable power support for end devices and user loads in the distribution network. This helps the distribution network achieve more efficient and reliable power distribution and operation in scenarios such as urban-rural power supply and small commercial-industrial power supply, contributing to the construction of an intelligent and stable power distribution and consumption ecosystem.
Product Features
Precision Voltage Regulation
32-step voltage adjustment (±10% range, ~0.625% per step) for smooth and accurate voltage control.
Suitable for single-phase power distribution systems (2400V to 34,500V, 50/60Hz).
Robust Construction
Oil-immersed auto-transformer design ensures durability and efficient heat dissipation.
High-creep porcelain bushings and MOV-type arresters provide superior insulation and surge protection.
Smart Control & Monitoring
RVR intelligent controller with GPRS/GSM/Bluetooth for remote monitoring and adjustments.
Real-time voltage & current sampling via built-in sensors (CT/PT inputs).
Key Advantages
High Reliability: Oil-immersed construction and conformally coated PCBs ensure long-term stability in harsh environments.
Wide Compatibility: Supports 60Hz & 50Hz systems with voltage ratings up to 34.5kV (200 kV BIL).
Automated & Remote-Controlled: Smart controller enables real-time adjustments via mobile or SCADA systems.
Enhanced Safety: Built-in fault protection and pressure/oil monitoring prevent catastrophic failures.
Low Maintenance: Modular design simplifies servicing (e.g., tap changer motor, replaceable bushings).
Technical Specifications
Some of the voltage ratings include 50Hz (6kV, 6.35kV, 11kV, 15kV, 22kV, 33kV) and 60Hz (7.62kV,13.2kV 13.8kV, 14.4kV, 19.92kV, 34.5kV). Customization is available.

Why Choose the RVR-1?
The RVR-1 Automatic Voltage Regulator combines precision, durability, and smart control to optimize power distribution efficiency. Its 32-step fine-tuning capability ensures stable voltage delivery, while remote monitoring minimizes downtime. Ideal for utilities and industries requiring reliable voltage regulation in medium-voltage networks.
No. Adopting a design of step voltage regulation + induction regulation, it realizes smooth voltage switching. Combined with the buffering characteristics of oil-immersed insulation, it can avoid voltage surges that may impact the power grid and downstream equipment, making it suitable for scenarios requiring high power supply stability.
It mainly requires regular inspection of the insulation oil level and quality (at least once a year), cleaning dust on the radiator surface to ensure heat dissipation efficiency, and monitoring the operation status of the tap changer. These maintenance measures can guarantee the long-term stable operation of the equipment, and professional power operation and maintenance personnel are recommended for the operations.
