3241 is a semiconductor laminated glass cloth sheet made of alkali free glass fiber cloth immersed with epoxy phenolic resin add conductive component by hot pressed to form into laminated products that has semi conducting performance suitable for corona resistant material of a large high-voltage motor slot.
The appearance of semiconductor laminated glass cloth sheet need no bubbles , pits or wrinkles. It allows a little of spots. The edges need to be cut neatly and the end face must not have layer or cracks.
