Insulating cable paper

Insulating cable paper

It's made of 100% high-quality sulfate insulating wood pulp.

Features:

1.This paper has stable electrical and chemical properties, and high physical strength to meet the exact requirements of our valued customers.  

2.Insulating paper available in nominal thicknesses from 40um to 250um, and in continuous rolls up to the widths of 470mm, 625mm, 960mm, and1000mm(the roll diameter being 680mm-730mm). 3.Other customized diameter and width depend on customers' needs.

Advantages:

1.The insulating cable paper is manufactured from 100% high quality sulfated insulating wood pulp. No sizing or fillers are used. 

2.This paper is highly refinded and cleaned to ensure uniform thickness and formation. Pinholes, undispersed fiber bundles and tiny defects, It is minimized to meet the safety requirements in the manufacturing and applications of transformers and cables. 

3.It is a low-voltage grade insulating paper well suited for making electromagnetic below wires, power cables of transformers below 35kw and other electrival insulating equipments below 35kw.
