Abstract

Sistema de corriente trifásica de alta tensión en disposición horizontal y cablesunipolares con una disposición de protección magnética para los cables eléctricosunipolares: * Donde cada cable unipolar incluye un conductor del cable (12) y unaislamiento de plástico (14) con una capa conductiva interna y externa,y la disposición de protección consta para un único cable unipolar * De una protección metálica (20) que rodea radialmente el cable unipolardispuesto por encima del cable unipolar * Rodeado de una protección metálica (20), íntegramente encintado (22)con un material de alta permeabilidad, y * Los protectores metálicos (20) presentan en sus extremos técnicas decontacto para el contacto de protectores metálicos entre sí, con lo cual, para la reducción del factor de pérdida eléctrica en la protección metálica(20), la protección metálica (20) está formada de una conductividad eléctrica que seencuentra en el área 80% hasta 150% de la conductividad eléctrica del conductor decable (12).Three-phase high-voltage current system in horizontal arrangement and single-pole cables with a magnetic protection arrangement for single-pole electrical cables: * Where each single-pole cable includes a cable conductor (12) and a plastic insulator (14) with an internal and external conductive layer , and the protection arrangement consists of a single unipolar cable * Of a metallic protection (20) that radially surrounds the unipolar cable disposed above the unipolar cable * Surrounded by a metallic protection (20), completely taped (22) with a material of high permeability, and * The metallic protectors (20) have in their extremes contact techniques for the contact of metallic protectors with each other, with which, for the reduction of the factor of electrical loss in the metallic protection (20), the metallic protection ( 20) is formed of an electrical conductivity that is in the area 80% to 150% of the electrical conductivity Decable conductor ica (12).
