The transformer station door (TrafoSt):

The transformer station doors, which are individually manufactured according to customer requirements, serve to protect electrical systems. They are equipped in accordance with the regulations of DIN EN 62271-202 (VDE 0671-202).

In order to ensure sufficient air exchange to maintain the function of electrical components, the transformer station doors are equipped with ventilation grilles.

These have an optimized slat geometry and a special door leaf connection. To ensure the required burglar resistance of access doors, the Hodapp company launched the TrafoSt steel solid leaf door system, which was specially developed for this application.
