Single-phase cast resin transformers for railway engineering


The technical solution was worked out bearing in mind the application of the transformers in the systems for protective separation of electric heaters for heating up EOR crossovers from supply devices near the tracks.
The transformers are adjusted for fastening in hanging position, in the EGC-102 boxes near the tracks.
The fastening slots are placed in accordance with the standard hole spacing used in railway devices.
