Cable Insulation Paper
Callback
Cable insulation paper is manufactured from 100% high-quality sulfate insulating wood pulp.
This paper is highly refined and cleaned to ensure uniform thickness and free from formation Pinholes, un-dispersed fiber bundles and tiny defects
It is a low-voltage grade insulating paper well suited for making electromagnetic wires, power cables of
transformers below 35kV and other electrical insulating equipments below 35kV
This paper has stable electrical and chemical properties, and high physical strength to meet the exacting
needs of our valued customers
