Single-phase power transformers
We manufacture single-phase transformers in the power range 6.3 to 630 kVA. Our selection includes the Power Series and electrostatically shielded transformers.
The standard structure is open frame IP00, but the transformers are available up to IP65.
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 secondary windings, different settings, intermediate outputs, casters or other accessories requested by the customer.
