INSULATING STRUCTURE WITH SCREENS THAT GENERATE ELECTRIC FIELD Russian patent published in 2011 - IPC H01B17/28 

FIELD: electricity.

SUBSTANCE: insulating structure comprises screens that generate an electric field, which may be used in high-voltage bushings, high-voltage cables, cable fittings and in metering devices, especially in metering transformers. The structure, according to the invention, comprises layers of an electric insulation material, between which there are conducting plates, such as screens that generate the electric field in the high-voltage electric equipment. Conducting sheets are made of a layer of an insulating substrate with a porous structure impregnated and compressed in direction parallel to the sheet plane, and at least one surface of the substrate layer has a well-developed surface and is coated with a metal layer. The layer of the electric insulation substrate is cellulose paper of electric insulation type. The layer of the electric insulation substrate is a nonwoven cloth made of polymer fibres.

EFFECT: conductivity improvement.
