Product Description

PHENOLIC LIMINATED PAPER TUPE

Basic information and application :
This product is made of insulating winding paper impregnated with phenolic resin, heated, rolled and baked. It has high dielectric properties. It can be used as insulation components in electrical appliances and transformer oil.

Exterior :
The surface shall be smooth, and no defects such as delamination and bubble edge are allowed. Slight wrinkles, bubbles and die indentation that do not affect the vertical withstand voltage are allowed on the inner wall. The end face shall be cut neatly, and slight cracks are allowed on the end face if the wall thickness is more than 13mm.
