Industrial Transformer
Industrial duty is harder than commercial duty.
An industrial transformer feeds production equipment: motors, drives, furnaces, compressors, pumps, process lines and the ancillary building services that keep a plant running.
Industrial duty is harder than commercial duty. Loads are often continuous, unbalanced and rich in harmonics from variable speed drives and rectifiers. Our industrial designs take that into account — through winding configuration, K-factor or harmonic consideration, cooling margin and insulation class — so the transformer does not become the bottleneck that stops your line.

Manufacturing, Testing and Standards
Every unit is built under documented process control and subjected to routine tests before dispatch: winding resistance, voltage ratio and vector group, impedance voltage and load loss, no-load loss and current, applied and induced voltage dielectric tests, and functional checks of accessories. Type tests — including lightning impulse, temperature rise and short-circuit withstand — are available for new designs and project requirements. See our testing and quality control pages.
