Abstract

PROCEDIMIENTO PARA HERMETIZAR LONGITUDINALMENTE UN CABLE DE TELECOMUNICACIONES. ENTRE LA CINTURA (6) Y LA PANTALLA (7) HAY UN ESPACIO QUE SE LLENA CON UNA MATERIA DE RELLENO SUSCEPTIBLE DE HINCHARSE EN PRESENCIA DE AGUA. SE DEPOSITA SOBRE LA CINTURA Y ESTA CONSTITUIDA POR UN POLVO TAL COMO CARBOXIMETILCELULOSA, O DERIVADOS SIMILARES COMO HIDROXIETIL CELULOSA O METILCELULOSA, DISPERSANDOSE DICHO POLVO EN UN AGENTE VISCOSO QUE NO SUPRIME LA CAPACIDAD DE HINCHAMIENTO EN PRESENCIA DE AGUA DE DICHA MATERIA DE RELLENO, TAL COMO POLIBUTENO, GLICERINA Y CERAS HIDROSOLUBLES.
