Magnet Wire, Keeps Transformers & Generators Moving Power

The energy segment focuses upon delivering power where and when it is needed. At Essex, we have that focus in common. We have the magnet wire products and services to meet the transformer or generator manufacturer’s unexpected demands. A full range of continuously transposed cables (CTC) with single and multi-conductor configurations can be built to your specifications. Plus a full complement of wrapped round or shaped wire with enameled or bare wire is available.

Essex Has All the Shapes, Sizes, and Insulation Types You Need

From enameled to extruded, and bare to wrapped, we have the magnet wire shapes and sizes you need to build a transformer or generator.

For oil-filled transformers consider Essex Polyflex™ 225 wire. We extrude a polymer over an aluminum conductor to provide an abrasion resistant, high temperature wire that is compatible with various transformer oils. It features increased dielectrics and a high resistance to mechanical damage from winding processes.

For Large Power Transformers, we offer Continuously Transposed Conductors including configurations with B-Stage epoxy. For CTC, multiple conductors are assembled together and each order is customized to match transformer designs and customer requirements. At the same time, we can supply a full range of wrapped conductors—glass, Mica, Nomex, or Kapton.
