- Railway & Transportation Transformers
Overview
ESTA Transformer designs and manufactures transformer solutions for railway and transportation infrastructure using a fully engineered-to-order approach, rather than catalogue-based products.
Railway applications require continuous operation, high resistance to shock and vibration, wide ambient temperature ranges, and maximum operational reliability.
For this reason, ESTA does not offer standard products for railway projects; each solution is engineered from the ground up according to project-specific requirements.
Application Areas
ESTA railway transformer solutions are used in the following applications:
Metro and tramway systems
Railway infrastructure facilities
Signaling and control systems
Traction substations and auxiliary power systems
Depots, maintenance and workshop facilities
Transportation-related industrial installations
Product Groups
For railway and transportation applications, ESTA provides the following product groups:
