Tm transformers are made up to a power of 5.000 VA with a “mantle” type nucleus, for higher powers they are made with a “column” nucleus. On request the dimensions can be changes in order to fulfil any volume requirement.

Technical specifications:
– insulation class E
– frequency 50/60 Hz.
– open execution, protection level IP00
– ambient temperature 40°C
– either vertical or horizontal execution
– resin impreganted and tropicalised
– vectorial group Yy0 with accessible neutral conductor
– other vectorial groups on request
– standard execution with tensions included between 100V and 500V

Essential information for order and offers inquiries:
– power in VA or in KVA
– network tension and frequency
– output tension
– ambient temperature
– working ambient conditions
Primary Tension: 230-400Vac + N (accessibile)
Secondary Tension: 230Vac+N (accessibile) oppure 400Vac+N (accessibile)
Final code: 230+N=Cod.2 / 400+N=Cod.4
