Brief Introduction
FeaturesThis 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
ApplicationsUsed 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.
Insulating paper is wrapped in the outermost layer of the cable to protect the insulating layer of the conductive core and seal it against moisture intrusion or damage to the insulating layer. The paper is durable and even. It has high tensile, folding and tear strength. Free of metals, sand or conductive acidic substances. The dielectric constant is high. The paper has good stability when subject to insulating liquids. It is made from unbleached sulfate coniferous wood pulp, freely beaten, without sizing and without filling (material), and is made on a long wire paper machine. Used for insulation of wires or cables.
SpecificationsOur ordinary insulating papers are available in nominal thicknesses from 50 to 250 microns,
and in continuous rolls up to the widths of 625, 960mm and 1200mm (the roll diameter being 680 to 730mm),
or other customized diameters and widths on request.
