good quality transformer insulation cable paper

  insulation cable paper is manufactured from 100% high quality sulfated insulating wood pulp without sizing or used fillers   insulation cable 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   insulation cable 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   insulation cable paper's technical data:
