TMC produces low-voltage special and distribution VPI transformers with normal or reduced losses and according to customer specifications, up to 10MVA and with insulation class up to 1.1kV.
TMC designs, manufactures and test our machines according to all international standards: IEC, IEEE, CSA, UL, ANSI, NEMA, NRCan.
VPI transformers main feature:
The most common cooling technologies are based on air, either natural or forced; and liquid, either direct or indirect, or with an AFWF heat exchanger.
In addition, the ability to withstand short-circuit forces is verified with FEA software.
LV transformers are almost always present in manufacturing plant to adapt local LV voltages to specific machinery requirement or to feed low voltage converters to pilot a motor.
Common technology for LV transformers is VPI (Vacuum Pressurized Impregnation).
VPI Transformer IP23 AF for dynamic UPS.
VPI Transformer for Marine Converter.
VPI Transformer IP23 AN for wind sea farm.
VPI Transformer IP44 for Auxiliaries on Board Vessels.
VPI Transformer IP21 AN for test room variable voltage ratio and frequency.
Insulation level: 1,1 / 3 /-
Insulation class: H
Frequency: 50 Hz + ripple
