STEM TRAFO (STIMAMIGLIO SRL)

Exhibitor Profile

Our Main Production:

• Power and Special transformers up to 40 MVA
•  Furnace Transformers
• Reactors
•  VSR Regulators for Boosting Systems.

Our Voltage System Regulator for Glass Furnaces (VSR) makes an ON LOAD REGULATION in any situation .

Our VSR is not an induction regulator (motor with the rotor stuck) and is not a regulator with rollers or skids inside, it is not a static regulator, but it works only acting on the linkage flux.

Our VSR is similar and safe as a  standard  transformer because the only moving material is a shield .

The active part of the system is static, so the life of our VSR shield regulator is very safe and long as for a  normal transformer.

It is possible to make a VSR for every power required ( from 5.000 to 10 kva),  configuration ( 3-3/2-3/1-1 phase) , input voltage ( from 30 kv or more) and output voltage.
