The SVR series line automatic voltage regulator is essentially an autotransformer with continuously adjustable voltage. It automatically adjusts the on-load tap changer position based on line voltage conditions to alter the transformer's turns ratio, thereby maintaining the output voltage within a specific range. It is suitable for power supply lines characterized by long transmission distances, heavy loads, significant voltage fluctuations, or power quality that fails to meet operational standards. It can also be used by industrial and mining enterprises where voltage quality does not meet production requirements.
Product Details
DETAIL
The SVR series automatic line voltage regulator is essentially an autotransformer with continuously adjustable voltage output. It automatically adjusts the on-load tap changer position based on line voltage conditions to modify the transformer's turns ratio, thereby maintaining the output voltage within a specified range. It is suitable for power supply lines characterized by long transmission distances, heavy loads, significant voltage fluctuations, or power quality that fails to meet operational standards. It is also applicable to industrial and mining enterprises where voltage quality does not meet production requirements.
Product Features
Utilizes an autotransformer structure capable of automatic on-load voltage regulation within a ±20% range; features excellent control performance and communication capabilities, supporting the "four remotes" functions: remote measurement, remote signaling, remote adjustment, and remote control; employs advanced anti-interference measures to ensure reliable controller operation; includes high- and low-limit protection for tap positions to prevent the tap changer from jamming; features separate oil tanks for the on-load tap changer and the autotransformer body;
Compact size, high capacity, lightweight, and low losses; easy to install; offers significant energy-saving benefits; high reliability.
Structural Characteristics
The automatic line voltage regulator extends the power supply radius of substations, making it suitable for long-distance power transmission in rural grids; it measures line voltage internally; ensures that voltage across the entire line meets national standards after regulation, with user-definable high and low regulation limits; effectively reduces line losses and distribution transformer losses; allows for the regulator to be switched into or out of service without interrupting the power supply.

FAQ
Are you a factory or a trading company?
Manufacturing Facility. Headquartered in Gaocheng District, Shijiazhuang City, Hebei Province, the company operates a 20,000-square-meter standardized workshop. Integrating R&D, design, production, and foreign trade, it maintains control over quality and costs right from the source.
Is product customization (OEM/ODM) available?
We can accommodate this. Our experienced technical team offers precise customization in strict accordance with your technical drawings, local grid standards (such as IEC and IEEE/ANSI), and specific environmental requirements.
How long is the warranty period? What kind of after-sales support is provided?
All units undergo rigorous testing before leaving the factory. We offer a warranty period of 12 to 24 months (depending on the model), along with lifetime 24/7 remote technical support and online troubleshooting.
What advantages do your transformer cores and silicon steel offer?
We independently process high-performance silicon steel and manufacture transformer cores in-house. Controlling the process at the source ensures excellent magnetic permeability, significantly reducing transformer no-load losses (delivering superior energy efficiency) and operating noise.
How do you choose between dry-type and oil-immersed transformers?
Dry-type (including open-ventilated): Air-cooled, flame-retardant, and maintenance-free; suitable for indoor environments with high safety requirements, such as shopping malls, hospitals, and subways. Oil-immersed: Cooled by insulating oil, offering excellent heat dissipation and strong overload capacity; suitable for industrial and mining enterprises, heavy-industry power grids, and harsh outdoor environments—offering the best cost-performance ratio.
Are box-type substations suitable for outdoor new energy projects such as photovoltaic power generation?
They are ideally suited for the application. Our PV combined substations and box-type substations feature high IP ratings—offering protection against weather, dust, and corrosion—along with excellent thermal insulation, and are specifically designed for harsh outdoor environments and integration with new energy power grids.
What are the safety standards for high- and low-voltage power distribution cabinets?
Designed and manufactured in strict accordance with international standards such as IEC. Equipped with reliable mechanical interlocking, arc-flash protection, and intelligent monitoring modules to ensure operator safety and stable system operation.
How should heavy equipment be packaged for long-distance ocean transport?
Sturdy, seaworthy packaging is used. The equipment is securely fastened to steel or heavy-duty wooden pallets, wrapped internally in moisture-proof vacuum film, and protected by an export-grade wooden crate; professional reinforcement during packing ensures full protection against impact during transit.
