STOP! Quality first!
Transformers and chokes mounted under the chassis and on the roof of a rail vehicle are directly exposed to harsh environmental conditions: water, snow, fog, conductive dirt and salinity.
See the thermal shock test to which we subject ELHAND products intended for the railway industry to ensure their highest quality and long-term operation in demanding conditions.
The thermal shock test of the transformer presented is one of many tests to which it was subjected before it was put into operation, including:
- lightning stroke test
- trials and tests with positive results, as agreed by the customer
- trials and tests with positive results based on the standards IEC 60076-11 and IEC 60310
