DyTerm®
Coveme DyTerm® insulating products derive from the coupling of Nomex® aramid paper with polyester or polymmide (Kapton®) films. Nomex® layers stick firmly to the plastic films by appropriate adhesives. DyTerm® laminates are suitable far use in electrical apparatus with ratings:
- up to 155°C class F: types N2S,N3S
- up to 180°C class H: types N2D,N3D
- up to 200°C class C: Kapton® based laminates.
The presence of films inhances the mechanical, physical and dielectrical properties of the laminate.
Coveme DyTerm® products are available in a wide range of different combinations, normally double or triple, but it is possible to reach other structures.
DyTerm® laminates are a highly performant solution to insulate 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 weII as to separate phases on the heads of the windings.
In transformers and electrical static equipments, DyTerm® is used as interlay insulating material.
