Specifications transformer Insulation paper

1. Made from 100% superior sulfate insulating wood pulp

2. For power cables, communication cable

  transformer Insulation paper  is manufactured from 100% high quality sulfated insulating wood pulp without sizing or used fillers   transformer Insulation 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.   transformer Insulation paper is used for wire, cable, liner insulation, tank insulation, transformer insulation and internections. It is suited for making electromagnetic wire of transformers and other electrial insulating equipments.   transformer Insulation paper's technical data:
