Trasfor - Transformers and Reactors for Rolling Stock

The IRIS standard, the latest to regulate applications in the rail sector, sets out very strict standards for usage in this field. This type of application is characterized by the aggressive environmental conditions, a restrictive MTBF rate (Mean Time Between Failures), the practical exclusion of maintenance and repetitive electro-mechanical stress. In addition, there is the safety aspect regarding the installation position of the units. A positioning that needs to satisfy the required mechanical behavior during freezing, shocks and vibration, and demands the employment of highly competent specialists. Simulations with FEA tools in order to predict the behaviour of the components against shock, vibrations and fatigue stresses are used.
