Railway transformers

Bearing in mind the specific needs of the railway industry, we manufacture and supply KBI, ATI and API series transformers for a wide range of applications.

We offer KBI shaped transformers for signal lanterns and SSP, as well as their toroidal counterparts - ATI and API. These transformers are used in voltage converters, SRK, SHL and SOT systems. In the production process, we use vacuum impregnation and resins pouring for hermetic and intrinsically safe products.

Railway transformers - KBI series

These are shaped transformers with a wide range of applications in railway traffic control devices.

Railway transformers - ATI series

These are toroidal transformers, which are a more and more often chosen alternative to the commonly used shaped transformers in the railway sector.
