All materials used in our production is UL/CSA listed, when applicable. Multi-source purchasing policy is maintained whenever necessary to assure availability and no interruption on the shop floor.
As our transformers are American made and we take great pride in what we do, all materials when available, are quoted and purchased from local and U.S. based vendors.
Laser scribed or Plasma etched High-B, grain oriented Silicon Steel is used in our core production. Sample test is done of each lot and size. Cores for applications that require Low-B steel are purchased and subject to the same inspection procedures. Maintaining high Core quality is important for the overall performance of our transformers.
