Paper Composites Excellent tear resistance and flexibility, easy to be applied. Low dielectric dissipation
Paper Composites
Characteristics:
*High mechanical strength, good dielectric strength with thinner slot insulation ply.
*Good thermal stability, it can work for a long term under 180°Cfor class-H insulation.
*Excellent tear resistance and flexibility, easy to be applied.
*Low dielectric dissipation, it can work in harsh condition
