1. COMPOSITION AND PRESENTATION
They are made from insulating winding paper, cellulose fabric or specially electric no-alkali glass cloth, impregnated phenolic resin, epoxy resin rolled upon mandrels under tension or between heated pressure rolls, or both and than oven-baked, cured.
At delivery time the presentation of the sheets is as follows:
|
Surface: should be even. Size: Normal diameter: 10mm-1200mm Range of wall thickness: 1.5mm-50.00mm Normal length: 450mm-1000mm |
|
|
- beyond the above size should be discussed between buyers and sellers. |
