Title:
MANUFACTURE OF ELECTRIC INSULATING LAMINATED PAPER, AND OIL IMERSED POWER CABLE USING THE LAMINATED PAPER
Document Type and Number:
Japanese Patent JP3437750
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated paper excellent in a dielectric characteristic, a withstand voltage property, a mechanical characteristic, and adhesive strength in particular, and a power cable using the laminated paper.
SOLUTION: As this manufacture, first, craft insulating paper 1 to be integrated with a polyolefine resin 2 as a binder is meltedly extruded by an extruder. Then, this integrated electric insulating laminated paper is calendered or super- calendered to make whole thickness 30-200μm, and the ratio of polymer compsed of the polyolefine resin, is set to 40-90%. The laminated paper obtained by this method is made to be used for this power cable.
