Not a stock item

Coiled, multi-layer insulating and protective conduit for applications in temperature class B.

  • Inner diameter from 1.60 mm to 210.00
  • available with wall thicknesses from 0.030 mm to 2.00 mm.
  • Precise, non-shrinking polyester insulating pipe for applications up to 155 °C.
  • Material UL approved

The non-shrink insulating conduit made of Mylar® A is used for robust insulation in electrical applications. It is also available with an electrically conductive surface coating for special applications. It is wound very precisely from polyester film. It has a high dielectric strength and mechanical impact resistance and is also suitable for demanding applications. It is mainly used as secondary insulation in windings of lacquer-impregnated and open electric motors.
