Abstract

PROCEDIMIENTO PARA MEJORAR LA RIGIDEZ DIELECTRICA DEL AISLAMIENTO DE CABLES Y/O OTROS COMPONENTES PARA CORRIENTE CONTINUA.COMPRENDE UN CONDUCTOR (11); UNA PANTALLA SEMICONDUCTORA INTERNA; UN AISLAMIENTO; UNA PANTALLA SEMICONDUCTORA EXTERIOR, ENCERRADO TODO ELLO EN UNA FUNDA METALICA RECUBIERTA POR UNA FUNDA ANTICORROSIVA. CONSISTE EN ALIMENTAR EL ELEMENTO CONDUCTOR (11) CONECTADO A LA CARGA (17) CON UNA TENSION RESULTANTE DE LA SUPERPOSICION A UNA TENSION CONTINUA (DC), DE UNA TENSION ALTERNA (AC) QUE TIENE UNA AMPLITUD PREFIJADA ENTRE 95Y 10 DE LA TENSION CONTINUA Y AL QUE SE SHUNTA POR MEDIO DE UN INDUCTOR (18).
