Description of Electrical insulation paper PMP :
PMP is one composited insulation which is made of two layer condenser paper and middle is polyester.
Characteristic and Application for Electrical insulation paper PMP :
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.
