Look beyond the nameplate capacity
Thermal class describes the insulation system’s temperature capability. It is distinct from the transformer’s specified temperature rise. Both matter when evaluating loading conditions and the operating environment.
Match the insulation system to the application
Supertran offers 120°C and 140°C insulation systems, including options using FR3 natural ester fluid. The appropriate choice depends on the final design, duty, ambient conditions, and project requirements.
Consider the whole operating environment
Data centers, motor-driven loads, solar projects, and other demanding applications can introduce different thermal and harmonic conditions. Share your loading profile so the equipment can be reviewed as a complete system.
Confirm usable capacity with an engineer
Higher thermal class options can support additional loading capability in an appropriate design. Continuous loading, cooling, and protection requirements should be verified for the specific transformer rather than assumed from a general product range.
