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 its machines according to all international standards: IEC, IEEE, CSA, UL, ANSI, NEMA, NRCan.

VPI transformers main feature:

• aluminium or copper windings
• class F or class H (180°C) insulation systems
• compatibility with both indoor and outdoor installations

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.
