Three-phase power transformers

We manufacture three-phase power transformers in the power range 6.3kVA to 2MVA. Our selection includes Power and Eco Series, auto-transformers and electrostatically shielded transformers. Transformers in the Power Series have been designed to be cost-efficient, and transformers in the Eco Series to have very low power loss.

The standard structure is open frame IP00, but the transformers are available up to IP65. Power Series transformers feature separate primary and secondary windings, which creates an isolated network.

The transformers are intended for applications which require voltage increases or decreases or in which the transformer is used as an isolation transformer. If the voltage change does not require isolation, the solution might be an auto-transformer, which is smaller in size and more cost-efficient. The transformers are used in different kinds of industrial, construction, energy technology and marine applications, such as electric motors, compressors, cooling systems or IT/TN-S network formation. On request, transformers can be manufactured for different voltages and frequencies, and equipped with e.g. an electrostatic shield between the primary and secondary windings, different settings, intermediate outputs, casters or other accessories requested by the customer.
