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
Transformer for naval propulsion
The electrical propulsion systems have many advantages compared to the conventional engine driven propulsion system. This technology is required due to the increasing demand for electrical propulsion for different vessels, such as cruise ships, container ships and navy ships. With advancement in technology and research, the electrical propulsion system is not limited to small boats and small vessels anymore.
This solution is for a transformer for a motor driver with 12 pulse bridge rectifiers, a nominal power rating of 3.5MVA, a primary voltage of 11kV and a frequency of 60Hz.
Installation is indoor in a vessel hull with IP44 protection and an air-to-water heat exchange (AFWF).
Transformer is fully certified by a (third party) naval register.
- Power: 7,5 MVA
- Primary Voltage: 11kV, 60Hz
- Secondary Voltage: 2 x 1,8kV
- Protection: IP44
- Cooling: AFWF
