Product Description
Transformer insulating Pressboard
1.The Insulation Transformer Pressboard is manufactured from 100% high quality sulfated insulating wood pulp. without sizing or used fillers. This paper is highly refinded and cleaned to ensure uniform thickness and formation. It is allowed to exist for little Pinholes, Undispersed fiber bundles and Tiny defects if it doesn't effect to meet the safety requirements in the manufacturing and applications of transformers and cables.
2.It is suited for making electromagnetic wire of transformers and other electrial insulating equipments Specification:
3.nominal thicknesses:1.0-8.0mm
4.size:1000mmX2000mm 2000mmX4000m
