NMN

详细说明

DESCRIPTION

NMN is a flexible 3 layers insulation material  consisting a polyester filmwith a calendered NOMEX^?, on external both sides.

PROPERTIES

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 varnish or resins results in exceptional bonding between all winding components.

APPLICATION

NMN is a cost effective insulation material and is used in electric motors as slot insulation , phase insulation and wedges.NMN is used as core, interlayer and final insulation for transformers.

STANDARDS

Thermal Class F (155oC)

Insulating material according to IEC 626-1

DELIVERY FORM Total thickness in mm.
