Power Distribution
From the pantograph to all power converters, the power distribution can include multiple functions that our solutions can fully support with a modular approach: protection via HSCB, energy measurement for billing, safety earthing system, and power line components necessary to feed converters.
Our High Voltage boxes can integrate all these components combining standard modules in compact, flexible and digital solutions.
- Easy wiring, installation, and access for maintenance
- Short time-to-market thanks to smart design solutions
- Plug-and-play, fully tested products
- New intelligent unit for digitalized control & diagnostic services to/from TCMS
