The ODCER transformer is a modern electrical device specially designed to convert the voltage of the contact network into the voltage required to power the traction motors of AC electric trains. Its functional capabilities allow it to work effectively in conditions of increased mechanical loads, vibrations and temperature fluctuations. Thanks to the use of advanced technologies, the transformer provides high reliability and energy efficiency when operating in difficult conditions of railway transport.
Design features
The ODCER transformer has a robust design, which is specially adapted for open installation under the body of an electric train. This provides maximum resistance to mechanical influences, such as shaking, shocks and vibrations that occur during the movement of the railway train. The transformer housing is made of high-quality materials, which guarantee protection against moisture, dust and aggressive external factors.
Its design includes:
- Power winding with optimized insulation for increased electrical strength.
- An effective cooling system that ensures stable thermal conditions.
- Anti-vibration mounts to reduce the impact of dynamic loads.
- Protective coating for operation in conditions of increased humidity and dust.
