The subject of the invention is an insulating structure with screens shaping the electric field, applicable in high-voltage bushings, high-voltage cables, cable accessories and in measuring instruments, especially instrument transformers. The structure according to the invention comprising layers of electrically insulating material between which there are inserted conducting sheets which are screens shaping the electric field in high-voltage electric power equipment is characterized in that the conducting sheets are made of an insulating substrate layer with a porous structure, impregnatable and compressible along the direction parallel to the sheet plane, and at least one surface of the substrate layer has a strongly developed surface and is coated with a metal layer.
