Insulation kraft paper,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
--Used widely as electrical insulation wrap on aluminium and copper wires by conductor manufacturers,
--electrical insulation between layers of wound coils in electrical motors, in capacitors, transformers & such other electrical equipment.
