SynTherm® – Insulating Materials

SynTherm® NPN/130

SynTherm® NPN/130 is a flexible 3-ply insulation consisting of a polyester film with a calandered Nomex® layer.

Attributes

The proven dielectric properties of the polyester film and the excellent mechanical and thermal properties of the outer Nomex® layers result in a high performance insulating material. The ability of the outer layers to absorb impregnants results in exceptional bonding between all winding components. Smooth and abrasion resistant surface and therefore easy to machine processing.

Application

SynTherm® NPN/130 is used in electric motors as slot insulation, phase insulation and wedges.
SynTherm® NPN/130 is used as core, interlayer und final insulation for transformers.

Standards
  • Suitable for class H (180 °C) systems
  • Insulating material acc. IEC 60626
  • UL approved, e.g. E247773
  • RoHS compliant acc. to 2011/65/EU
  • Test standard IEC 60626-2
  • Sample conditioning acc. to standard atmosphere 23/50

It remains to be seen how things will continue. Crisis management dominates. It is simply impossible to make serious forecasts about future economic and social changes. All forecasts are plain guessing.

Thus, the resolutions remain: maximum solidarity, responsible action and best possible maintenance of all structures. There will be a time after SARS-CoV-2!

In this spirit we wish you all much steadfastness and good health.
