20 Mil (0.50 mm thick) Grade K Thermally Upgraded Kraft Press-Paper Flexible Laminate 105°C, brown, 48" wide roll
Part: KRAFTT/U.WEID.020
Manufacturer: Weidmann Electrical Tech. Inc.
Grade K Thermally Upgraded Press-paper is made of sulphate wood pulp and is used mainly as a layer insulating paper in low voltage and high voltage windings of oil-filled distribution transformers. The lifetime of the transformers is directly related to the condition of insulation paper of the winding.
Thermally upgraded paper is a cellulose-based paper that has been chemically modified to reduce the rate at which the paper decomposes.
The purpose of thermally upgrading insulation paper is to neutralize acids caused by thermal degradation of the cellulose over the lifetime of the transformer. Thermally upgraded paper retains a much higher tensile and bursting strength than untreated papers when exposed to elevated temperatures.
Electrowind Converting Solutions can custom slit-to-width, die cut and punch press custom parts, and sheet Kraft paper to your specification, along with other customized solutions. Request your quote for custom parts today!
