Key features

Epoxy Resin Vacuum Cast Insulation, Fully encapsulated windings provide excellent insulation performance, high dielectric strength, and superior protection against moisture, dust, and pollution

Low Loss & High Energy Efficiency ,Optimized magnetic circuit design significantly reduces no-load and load losses, ensuring energy-saving operation and lower electricity costs over the transformer's

Superior Fire Safety & Self-Extinguishing ,Non-flammable, halogen-free, and self-extinguishing materials eliminate oil fire risks and toxic gas emissions, making it ideal for indoor installations and

Environmentally Friendly Pollution Free ,No oil filling means zero risk of oil leakage, soil contamination, or water pollution , a clean, green solution for modern power distribution.

Low Maintenance , Long Service Life,With no oil to monitor, replace, or filter, the transformer requires minimal routine maintenance, significantly reducing operational and lifecycle costs.

High Mechanical , Short Circuit Strength ,Robust core clamping and coil structure provide exceptional resistance to sudden short circuits, preventing winding deformation and ensuring reliable operati

Ultra Low Noise Operation. Advanced winding technology and vibration-damping design minimize operational noise, making it suitable for noise-sensitive environments such as hospitals, data centers, an

Compact Footprint ,Space-Saving Design , Smaller dimensions compared to oil-filled counterparts allow flexible installation close to load centers, reducing cable losses and saving valuable floor spac

Strong Overload Capacity, Wide Temperature Adaptability , High thermal class insulation (Class H/F) supports continuous operation under overload conditions and adapts to a broad range of ambient temp

Wide Application Range ,Customizable Options ,Available from 30 kVA up to 6,300 kVA, covering voltage classes up to 35 kV, suitable for commercial buildings, industrial facilities, renewable energy

Q:Do you support product customization?

Yes. We offer OEM/ODM customized services based on customer drawings, technical specifications, or project requirements. Customization options include but are not limited to: voltage level, capacity, dimensions, color, materials, and wiring configurations.

Q:What information should I provide for a custom order?

To ensure accurate quotation and production, please provide the following: Product type and model; Rated capacity/power; Primary/secondary voltage levels; Frequency (50Hz/60Hz); Connection group; Impedance voltage; Cooling method; Insulation class and temperature rise requirements; Installation environment (altitude, temperature, humidity, etc.); Protection level requirement; Applicable standards (GB/IEC/ANSI, etc.); Quantity and required delivery date.

Q:How do I determine if my power distribution equipment needs upgrading or replacement?

It is recommended to evaluate the equipment when any of the following conditions occur: The equipment has been in operation for many years and loads are increasing; Frequent faults or overheating occur; Insulation performance has noticeably declined; Spare parts are difficult to source; The equipment can no longer meet current load requirements or new access requirements; Relevant standards or regulations have been updated.
