Efacec always favoured technological development as a main factor to ensure competitiveness and high quality of its transformers.

An integrated Management system of all the required information for the design and manufacture of Power Transformers has been developed by Efacec.

Power Transformers 

• SHELL Transformer | 1000 MVA; 525 kV (BIL 1675 kV)
• CORE Transformer | 250 MVA; 275 kV (BIL 1175 kV) 

Mobile Substations 

• Core ou Shell | 60 MVA; 245 kV (BIL1050kV)

Distribution Transformers 

• Hermetic, mineral oil immersed three-phase distribution transformers from 50 up to 6300 kVA, up to 36 kV for indoor or outdoor installation.
• Cast resin dry type three-phase distribution transformers from 250 to 6300 kVA, up to 36 kV, comercially know as PowerCast.
• Large  - Conservator oil immersed transformer up to 20 MVA and 66 kV for indoor and outdoor installation, with on-load tap changer and radiator cooling.

Our activities cover Turn Key Engineering Systems including:

•  Basic and detailed project
•  Procurement
•  Erection and testing

These activities also cover R&D, where skilled and innovative teams are responsible for state-of-the-art software and hardware development.
