Transformers and substations built to your specification

We don't sell a fixed catalogue: every unit is defined to the project and manufactured under our brand at qualified partner factories. Our European range is specified to the applicable CE, IEC / EN 60076 and Ecodesign requirements. US 60 Hz projects are quoted separately against the utility specification; solar inverter and step-up integration is offered within the skid and containerised range.

The stated NF EN, IEC and Ecodesign requirements apply to the European range. US-market transformers are quoted against the applicable project, utility and local requirements; the accepted standards, testing and documentation scope are stated in the quotation. Solar conversion integration is specified as part of the skid or containerised substation scope. See European compliance →
