Litz Wire Types and Constructions
New England Wire Technologies is a pioneer and leading designer and manufacturer of Litz wire and specialty winding wire. 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. We offer all 9 types of Litz wire constructions with multiple varieties of insulation to meet agency and/or specific customer voltage withstand requirements.

Many Litz wire constructions are available with multiple layers of insulation to meet voltage-withstand requirements of UL and IEC. Multiple extruded layers of fluoropolymers such as FEP, PFA and ETFE are most common. These extrusions are offered in different colors so that the different layers are easily distinguishable.  Learn more about our proprietary NEWind® specialty winding wire products.

Various tape wraps such as polyimide and polyester are available for applications requiring greater cut-through resistance and minimum diameter. These products, most commonly used in power conversion equipment, are desirable in any application requiring additional voltage withstand between windings. 

All of the insulations available for complex bundles are also available over single-strand bare, tinned and silver-plated copper as well as various copper alloys and magnet wires.
