I vantaggi tecnici ed economici dei trasformatori in olio

Thanks to the decades of experience from our partner company, Elettromeccanica Piossasco, our range of three-phase oil-immersed transformers is able to meet even the most demanding customer requirements in terms of:

Efficiency and energy savings
The possibility of installation in tropical climates with temperatures up to +55°C

Low noise levels
Customised designs based on client-specific technical requirements
Commercial and technical support in project development
