Abstract

PERFECCIONAMIENTOS EN LA FABRICACION DE CABLES ELECTRICOS QUE NO PROPAGAN LA LLAMA, IMPREGNADOS CON FLUIDO AISLANTE.CONSTA DE UN CONDUCTOR (1); UN AISLANTE (4) SOLIDO ESTRATIFICADO, FORMADO POR MATERIAL CELULOSICO DISPUESTO ALREDEDOR DEL CONDUCTOR (1) E IMPREGNADO; Y UNA ENVOLVENTE DE CONTENCION LLENA DE FLUIDO AISLANTE. LA IMPREGNACION DEL AISLANTE SOLIDO ESTRATIFICADO ES REALIZADA CON UN FLUIDO AISLANTE FORMADO POR LA COMBINACION DE UN POLIDIMETILSILOXANO QUE TIENE UNA VISCOSIDAD SUPERIOR A 5 CTS A 25JC, Y UN COMPUESTO AROMATICO DE FORMULA (I) DONDE R ES UN RADICALAROMATICO, Y DONDE EL COMPUESTO AROMATICO INTERVIENE EN UNA CANTIDAD INFERIOR AL 10 EN PESO RESPECTO AL PESO TOTAL DE LA MEZCLA.
