Water-cooled transformer

Superior Cooling Efficiency: Significantly outperforms air-cooled and oil-immersed transformers in heat dissipation. Water's high specific heat capacity and thermal conductivity enable rapid heat removal from windings and cores.

High Overload Capacity & Extended Lifespan: Maintains lower and more stable winding temperatures, slowing down insulation aging. This allows for short-term operation at 120%–150% of rated load and extends service life.

Low Noise Emission: Eliminates noisy cooling fans (typical noise levels of 60–75 dB for air-cooled units), reducing noise to approximately <45 dB (primarily from pumps), making it ideal for noise-sensitive environments.

Compact Design & Space Saving: Requires no large ventilation ducts or fan maintenance space. The footprint is typically 20%–30% smaller than that of air-cooled dry-type transformers, suitable for underground substations and offshore platforms.

Excellent Environmental Adaptability:​ The closed-loop cooling system prevents ingress of dust, salt mist, and moisture. Compatible with pure water or glycol mixtures for low-temperature applications.

Reduced Fire Risk:​ Utilizes epoxy resin casting and pure water circulation instead of flammable insulating oil, significantly lowering fire hazards and simplifying environmental and fire safety compliance.
