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.
