Cast resin special transformers

At TMC we use our vast experience and expertise to work with our customers to develop specialist solutions, designed specifically to suit their requirements. We produce cast resin special transformers up to a power rating of 25MVA at a system voltage of 52kV for a wide variety of applications, across a multitude of sectors.

TMC draws on its considerable know-how to assess the ability of products to withstand short-circuit forces (FEA analysis) and manage:

• cooling - not only with natural or forced air, but also with direct or indirect water
• installations in particularly polluted outdoor environments by studying and developing suitable solutions
• the combination of epoxy resin and foil winding ensures the ultimate in dielectric performance and short-circuit resistance
• aluminium or copper winding
• class F or class H insulation systems
• air cooling channels included in the coil for better thermal efficiency at power ratings >5MVA
