NEWind™ -- Litz wire constructions are available with multiple layers of insulation to meet the 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. Various tape wraps, such as polymide 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. These products also meet the requirements of UL1950 Annex U and IEC 60950. 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. Many of the constructions described here can be supplied as UL recognized components or manufactured to specific AWM styles. 18 – 40 AWG are available with supplementary or reinforced insulation for Class H systems and below. These products are UL recognized under category OBJT2. VDE approvals are available as well. Ask for NEWind™
