cable paper: 1.Low voltage 2.Even thickness and tisssue 3.Less than 35kV 4.Thickness:80micron,130micron,170micron, 200micron
Introduction(power cable paper)
Electrical cable paper is made of 100% superior sulfate insulation wood pulp, without any rubber and fliers. This paper has even thickness and tissue. Pinhole, undistributed coma and part-defects are within the safety scope of transformer and cable making practice. Electrical cable paper is low voltage insulating paper, suitable for making electromagnetic wire used for below 35KV transformer, Electrical cable and other electrical insulating equipments. This paper is electrical and chemical stability and high physical strength. It has three grades: Excellent, Grade one and qualified products. The basis thickness has 80μm,130μm,170μm,200μm.This paper belongs to roll paper and the width of the roll is 625mm. The paper of other thickness and width can produce according to the contract.
