Description
-Name: Composite Insulation Paper For Transformer
Composite Insulation Paper For Transformer(AMA) is a three-layer composite electrical insulation material, which is composed of the following three materials:
A – M – A(Aramid / Mylar / Aramid)
This structure combines the excellent thermal resistance and mechanical strength of aramid paper with the dimensional stability and dielectric performance of PET film, making AMA an ideal insulation solution for medium- and high-grade motors, dry-type transformers, and electrical equipment.
AMA insulation paper is widely used by motor manufacturers, transformer factories, and electrical equipment producers who require reliable insulation performance under elevated temperatures.
-Features:
Soft composite type combines the excellent high temperature resistance of aramid paper 220 °C, good mechanical toughness and good dielectric strength of polyester film. 3.Material: polyester film coated with two sides of aramid paper, using imported H grade glue
