Electrical Insulation

DyTerm® Nomex® based flexible laminates

Coveme DyTerm® insulating products derive from the coupling of Nomex® aramid paper with polyester films. Nomex® layers stick firmly to the plastic films by appropriate adhesives. DyTerm® laminates are suitable for use in electrical appliances with following working temperatures:

  • up to 155°C class F: type N2S
  • up to 180°C class H: types N1D,N2D,N3D, N3S
  • up to 200°C class C: Kapton® based laminates

DyTerm® laminates are a highly performing solution for the insulation of electric motors, transformers and electrical machines, at operating temperatures ranging of 155 -180 and 200°C.

In rotating machines, DyTerm® is used in slot closure and insulation, as well as to separate phases on the heads of the windings. In transformers and electrical static equipments, DyTerm® is used as interlay insulating material.
