Abstract

PERFECCIONAMIENTOS EN LA FORMACION DE REVESTIMIENTOS PARA CABLES ELECTRICOS. COMPRENDE UN CONDUCTOR ELECTRICO (1), RECUBIERTO POR UN AISLANTE (2) Y ENCERRADO EN UNA FUNDA (3). EL AISLAMIENTO Y/O FUNDA ESTAN FORMADOS POR UNA MEZCLA DE UNA POLIOLEFINA RETICULADA, QUE PUEDE SER UNA GOMA DE ETILENO-PROPILENO, UN TERPOLIMERO DE ETILENO-PROPILENO, UN POLIETILENO Y OTROS; UN POLIETILENO HALOGENADO, DONDE EL HALOGENO PUEDE SER CLORO O BROMO; UN COMPUESTO A BASE DE MERCAPTO-BENZOIMIDAZOL METILITATO; Y UN PRODUCTO DE CONDENSACION ENTRE UNA DIARILAMINA Y UNA CETONA,PREFERIBLEMENTE ENTRE LA DIFENILAMINA Y LA ACETONA. EL AISLANTE ASI FORMADO SE APLICA SOBRE EL CONDUCTOR, CALENTANDOSE EL CONJUNTO A LA TEMPERATURA DE RETICULACION DE LA POLIOLEFINA, 200GC, DURANTE UN TIEMPO DE 2 MINUTOS, DE TAL MANERA QUE ESTA QUEDA APTA PARA ABSORBER OXIGENO POR DESCOMPOSICION, INHIBIENDO O RETARDANDO EL ENVEJECIMIENTO POR OXIDACION Y CALENTAMIENTO DE LOS COMPONENTES DEL AISLANTE O REVESTIMIENTO.
