PMP is composited insulation which is made of two layer
capacitior paper and middle is polyester. film
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.
