Yuanchen Liquid Filled Power Transformer is core equipment for medium and low-voltage distribution networks – and they're a better, upgraded alternative to traditional oil-immersed transformers, with far higher safety and environmental standards. Yuanchen's Liquid Filled Power Transformer uses a high-performance liquid insulating medium, which delivers electrical insulation and heat dissipation.
Key Features
Environmentally Safe Medium
We fill the transformer with a flame-retardant, biodegradable insulating liquid that releases no toxic gases. This design meets the strictest fire safety and environmental regulations in the industry.
High-Efficiency Cooling System
We've optimised the cooling channels and designed a smart liquid convection structure for the unit. Even when the Yuanchen Liquid Filled Power Transformer is running under overload conditions, its temperature rise stays stable, ensuring consistent performance.
Maintenance-Free Robust Construction
The casing is fully sealed with precision welding, which eliminates any risk of leakage entirely. Internal components are treated with vacuum pressure impregnation, keeping them completely isolated from the external environment and negating the need for regular maintenance.
Compact and Flexible Design
Compared to traditional transformers with the same capacity, our liquid filled unit has a smaller footprint and is lighter in weight. This makes it easy to install and deploy, even in tight, space-constrained locations.
Our Advantages

System Certification Assurance
We follow the ISO9001 Quality Management, ISO14001 Environmental Management and ISO45001 Occupational Health and Safety Management systems rigorously. From R&D and design all the way to final product delivery, these systems ensure consistent quality across every step of the process.

Technical R&D Capabilities
As a national high-tech enterprise and a specialised, refined, distinctive and innovative SME, we have strong core capabilities in continuous medium formula refinement and product structural optimization. This lets us keep our product technology at the cutting edge of the industry at all times.

End-to-End Quality Control
We implement strict inspection standards for every stage of production, starting with raw material procurement and covering key processes like vacuum impregnation and hermetic welding. Every single transformer we make also undergoes type testing at nationally accredited testing centres for full quality validation.

Scalable Delivery Capacity
Our modern production base covers nearly 100,000 square metres and is equipped with serialised production lines. This setup lets us respond quickly to market demands and guarantee on-time delivery, even for large-volume orders.

FAQ
Q: What are the key differences between Yuanchen Liquid Filled Power Transformer and conventional oil-immersed transformers?
A: The main difference is the insulating medium. Our liquid filled transformers use flame-retardant, eco-friendly liquids, which offer much better fire safety and environmental performance. Conventional oil-immersed transformers, by contrast, use mineral oil.
Q: Does this type of transformer require specialised fire protection systems?
A: Generally, it doesn't. Because we use flame-retardant insulating liquids, building fire safety regulations set lower requirements for this transformer than for oil-immersed ones. That said, you should always follow the specific local fire safety regulations for your project site.
Q: What is the production lead time for standard products?
A: For our standard specification transformers, the production lead time is about 4 to 5 weeks. For customised products with special voltage or capacity requirements, we'll assess the lead time individually based on the detailed technical proposal for your project.
