Description

Product Description

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 single-phase step voltage regulator is an advanced tap-changing autotransformer engineered specifically for precise voltage regulation on 11kV overhead distribution lines. Exclusively manufactured in China with rigorous quality control, this compact and reliable device automatically adjusts line voltage within a ±10% range via 32 fine-tuning steps (approximately 5/8% per step), effectively mitigating voltage fluctuations caused by varying load conditions or grid instability.

Compatible with both 50Hz and 60Hz power systems, the RVR-1 offers flexible installation options—supporting pole-mounted, pad-mounted, or substation deployment to adapt to diverse distribution network requirements. Its robust design integrates a durable oil-immersed structure and intelligent tap-changing mechanism, ensuring long-term operational stability and low maintenance needs. Ideal for enhancing power supply quality in rural, suburban, or industrial areas, this regulator delivers consistent voltage output, protecting sensitive equipment and optimizing overall grid efficiency.

Product Features

Precise Voltage Control：32-step tap changer (±10% range) for accurate voltage stabilization.
Wide Compatibility：Supports system voltages from 2,500V to 19,920V (60–150 kV BIL) and currents up to 1,665A.
Advanced Digital Control：Programmable settings for voltage limits, communication protocols, and data logging.
Flexible Installation：Pole-mounted brackets, pad-mounted bolts, or substation bases (elevating platforms optional).
Robust Design：Internal tap windings and optional ratio correction transformer for diverse grid applications.

Advantages

High Reliability： Ensures consistent voltage output in harsh environments.
Customizable ：Adaptable to various system voltages and control requirements.
Low Maintenance ：Automated tap-changing reduces manual intervention.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?

Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I
