Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE FABRICACION DE UN AISLADOR, PARTICULARMENTE UN AISLADOR PARA UN DIVISOR CAPACITIVO O DE UN AISLADOR DE TRAVESIA, QUE LLEVA UN NUCLEO CENTRAL Y UN CUERPO AISLANTE ADAPTADO DE MANERA ESTANCA ALREDEDOR DE DICHO NUCLEO CENTRAL. SE INTERPONE ENTRE UNA PARTE DEL NUCLEO CENTRAL 21 Y EL CUERPO AISLANTE 22 UNA CAPA DE REVESTIMIENTO FLEXIBLE 28 QUE PERMITE COLMAR LOS RECHUPES, Y COMPENSAR EL EFECTO DE RETIRADA DE LA MATERIA INYECTADA. EL CUERPO AISLANTE 22 ESTA REALIZADO POR SOBREMOLDEADO DE DICHO NUCLEO CENTRAL 21 PREVIAMENTE REVESTIDO EN DICHA CAPA DE REVESTIMIENTO FLEXIBLE 28 CON UNA RESINA AISLANTE INYECTADA, PARTICULARMENTE TERMOPLASTICA O TERMOENDURECIBLE.
