•
•
The extreme flexibility of the heat reducing waves present on the transformer tank, allows to compensate the volume increases of the
insulating fluid related to its operating temperature.
The leak-proofness of the transformer tank prevents the absorption of
humidity, making it “Maintenance free”.
Reference Norms :
CEI EN 60067-1 to 10
CEI EN 50464-1
The phases of design and building, in addition to their compliance with
IEC EN norms, take into account the following rules:
ISO 9001 : 2008 regarding the quality standards and procedures.
ISO 14001 : 2004 regarding the environmental issues.
MF TRASFORMATORI guarantees the use of PCB free insulating fluids
free from PCB. The magnetic core is built of grain-oriented electrical steel
sheets and they use the step lap technique for their cut and assembly to
reduce the abnormal overheating risks and to decrease the noise.
The coils are designed and built so that the transformer may operate on
full-load conditions in strict compliance with A thermal class.
Note: on request, we may provide transformers with the same electrical
features but with a conservator.

The extreme flexibility of the heat reducing waves present on the

Reference Norms :
CEI EN 60067-1 to 10
CEI EN 50464-1
The phases of design and building, in addition to their compliance with

ISO 14001 : 2004 regarding the environmental issues.
MF TRASFORMATORI guarantees the use of PCB free insulating fluids.
The magnetic core is built of grain-oriented electrical steel sheets and
they use the step lap technique for their cut and assembly to reduce the
abnormal overheating risks and to decrease the noise.
The coils are designed and built so that the transformer may operate on

PARTICULARITIES OF AN OILFILLED TRANSFORMER
•
•
•
•
The extreme flexibility of the heat reducing waves present on the
transformer tank, allows to compensate the volume increases of the
insulating fluid related to its operating temperature.
The leak-proofness of the transformer tank prevents the absorption of
humidity, making it “Maintenance free”.
Reference Norms :
CEI EN 60067-1 to 10
CEI EN 50464-1
The phases of design and building, in addition to their compliance with
IEC EN norms, take into account the following rules:
ISO 9001 : 2008 regarding the quality standards and procedures.
ISO 14001 : 2004 regarding the environmental issues.
MF TRASFORMATORI guarantees the use of insulating fl uids free from
PCB. The magnetic core is built of grain-oriented electrical steel sheets
and they use the step lap technique for their cut and assembly to reduce
the abnormal overheating risks and to decrease the noise.
The coils are designed and built so that the transformer may operate on
full-load conditions in strict compliance with A thermal class.
Note: on request, we may provide transformers with the same electrical
features but with a conservator.
