Shanghai EK Investment (Group) Co., Ltd.

EKAI Quality Transformers and Electric Component at a reasonable price:
With a new concept EKAI Electric Group is offering customers a range of Quality Power Transformers and electric components each optimized technically and economically by the careful selection of conductor and isolation material.
In the past purchasers and plant engineers had to search suppliers to match the unique needs of their actual application to the manufacturers standard range of transformers. Considerations always include the trade off between the best technical solution and the most economic choice.
The choice of the best transformer concept is primarily dependant on the technical and qualitative requirements of the individual applications. These choices involve considerable price differences.
