R&D Capabilities

R&D Excellence
OMEK owns a provincial high-tech enterprise R&D center, an academician workstation, and a doctoral innovation workstation.
Innovative Evaporative Cooling Transformer Technology
We collaborate with the Chinese Academy of Sciences on industry-academia-research projects, jointly developing evaporative cooling transformers.
Our evaporative cooling transformer adopts a new type of liquid insulating material with unique and excellent properties as the insulating and cooling medium for transformers. Its characteristics are as follows:
– Safe, non-flammable and non-toxic
– Oil-free, environmentally friendly and energy-efficient
– Strong dielectric strength
– Excellent insulation performance
– Efficient cooling performance


Featured Products
– Single-Phase Hermetically Sealed Oil-Immersed Distribution Transformer with Rolled Core (10–160 kVA)
– Three-Phase Hermetically Sealed Oil-Immersed Distribution Transformer (30–10,000 kVA)
The production standards for the above products have been listed in the “Zhejiang Manufacturing Quality Standard”
Industry Standards and Contributions
OMEK has led the drafting of and participated in the formulation of the following standards. Selected standards include:
