Litz wire consists of a number of individually insulated magnet wires twisted or braided into a uniform pattern with the primary benefit of reducing AC losses in high frequency

windings. 

GPMEDTEK offers unlimited Litz wire constructions with multiple types of insulation to meet agency and/or specific customer voltage withstand requirements.

Because of the low electrical losses and ease of solderability, the enamels commonly used for insulating individual strands are Polyurethane and Polyurethane with a Nylon topcoat. However, other insulations may also be used. In many cases, Litz wire is insulated with an overall single or double wrap, or serving, of a textile, but is also available unserved.

When manufacturing motors, transformers, and other electromagnetic devices, magnetic fields are created by current in a wire. By raising the frequency, you create stronger fields and higher coupling, resulting in a loss in the materials due to two effects – Skin Effect and Proximity Effect. As the frequency rises, the current migrates to the skin and is pushed away by the field of its neighboring strand, making the core of the conductor useless.
