Electrowind offers and stocks the core magnet wire (winding wire) and electrical insulation materials that dry-type transformer or “cast resin” transformer manufacturers and rebuilders use. Choosing the correct products to use in your dry-type transformers is critical as these transformers are typically built to withstand varying types of environment including the unforgiving environments found in chemical process plants or in the outdoors.
Electrowind can supply the insulating materials and parts you need as a single component or assembled as a complete kit.
