Transformers designed around your application

Every project begins with a different on-site reality. Voltage, power rating, available footprint, installation environment, mechanical constraints, connections, or operating conditions: all of these factors can influence transformer design.

At WR, our approach is to start with these constraints to develop a solution tailored to the application, rather than trying to fit the project into a standard configuration.

Our team designs and manufactures dry-type electrical transformers for demanding industrial applications. Depending on project requirements, the design can be customized at various levels: electrical characteristics, winding configuration, material selection, core type, connections, enclosure, busbars, transition compartments, or integration with surrounding equipment.

This flexibility allows us to address a wide variety of applications, whether for power distribution, grounding, rectification, variable-frequency drive power supplies, or projects requiring a fully custom design.

The environment in which the transformer will be installed is also factored in from the very beginning. Some projects require enhanced protection against dust, water, snow, corrosion, or mechanical stresses. Others impose specific dimensions, tight spaces, or configurations that must facilitate transport, installation, or connections.

Therefore, design is not limited to the transformer's electrical characteristics. It also takes into account how the equipment will be integrated into the existing system and operated in the field.

This approach is built on integrated expertise. From specification analysis to design, engineering, manufacturing, and testing, every phase of the project is managed by WR's teams. Engineers, designers, electricians, welders, and technical personnel work together to turn project requirements into installation-ready equipment.

Our manufacturing capabilities allow us to build transformers ranging from 5 kVA to 20 MVA, with voltages up to 49 kV and insulation classes up to 220 kV BIL.

Depending on the application, transformers can feature copper or aluminum windings, various core configurations, busbars, transition compartments, custom enclosures suited to the environment, and diverse connection systems.

Every transformer undergoes a rigorous testing process prior to delivery. Routine tests verify dielectric characteristics, turns ratio, polarity, winding resistance, impedance, and electrical losses. Additional testing can also be performed depending on project specifications.

This ability to design, manufacture, and test equipment within our own facilities ensures complete continuity between initial specifications and the final product.

Whether dealing with a relatively standard configuration or a project with unique constraints, our goal remains the same: to deliver a transformer tailored to the application, the environment, and the true requirements of the project.
