in compliance with CEI96 - 1 CEI 14 - 8 IEC 726 regulations
single-phase transformers
TMC column

TMC series transformers are made up to a power of 25000VA with a column-type nucleus and with a parallel series connection.
On request the dimensions can be changed 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
- frame with earth connection
- resin impregnated and tropicalised
- electric class of protection l
- the full power is referred to the max tension
- coils separated in a column execution

Essential information for order and offers inquiries:
- power in VA
- network tension and frequency
- output tension, specifying the subdivision of power on secondary (in case of more secondaries).
- ambient temperature
- working ambient conditions
