NEWind® Double and Triple Insulated Winding Wires

New England Wire Technologies manufactures custom specialty winding wire and cable 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® Double and Triple Insulated Winding Wires solve this problem by insulating the conductors with multiple thin layers of insulation. Cable insulation layers are extruded in either two layers (known as double insulated or supplementary insulation) or three layers (known as triple insulated or reinforced insulation). This design ensures that defects in any one layer will not reduce the insulating ability. The result is motors and transformers that can be manufactured without additional insulation, thus reducing their cost and size.
