VPI medium voltage transformers
TMC produces medium-voltage transformers VPI transformers with power up to 25MVA and voltages up to class 36kV.
These products are typically required in thermal class C or R. The thermal class of the resin is the same as that of the insulating materials.
The insulating material is composed of aramid materials applied with double VPI cycles which perform well at maximum working temperatures and in the event of extreme thermal overloads.
The ability to withstand short-circuit forces is verified with FEA software.
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
