Description of PMP laminate insulation paper :
PMP laminate insulation paper is one composited insulation which is made of two layer condenser paper and middle is polyester. It named composite foil of polyester movie and capaciator paper(PMP).It has outstanding dielectric properties,and very good mechanical homes.
PMP laminate insulation paper particularly employed for unique voltage transformer,specifically class E motor and other electrical insulations.
Characteristic and Application:
1 Smooth and non-layer and non-foaming
2 It has good dielectric property and higher mechanical strength. So it’s the best choose to liner insulation of high-voltage transformer.
Storage:
By GB5591.1 provision of Chapter VII.
