Technical Information
New England Wire Technologies manufactures winding wire in single-end, stranded and Litz wire multi-conductor cable configurations. While magnet wire in the single-end or Litz wire form is the most common winding wire, its coating has been found to be susceptible to insulation loss between winding turns, separate windings and between the winding and the ground.
NEWind® multi-layer insulated winding wire solves this problem by insulating the conductors with multiple thin layers of insulation. NEWind® wire insulation layers are commonly extruded in single, double (supplementary), or triple (reinforced) layers that can reduce creepage and clearing distances. The result is motors and transformers that can be manufactured without additional insulation, thus reducing their cost and size.
