Abstract

Procédé permettant de réduire la hausse subie, lors d'une exposition prolongée à de l'eau ou de la vapeur d'eau, par la perte diélectrique d'un câble coaxial de télécommunication sous-marine dans lequel un diélectrique entoure un conducteur intérieur. On maintient au moins la région extérieure du diélectrique du câble à une température choisie entre 40 et 90 degrés C environ pendant un temps de durée choisie, ce temps étant assez court et la température assez modérée pour que les performances du câble ne subissent qu'une dégradation nulle ou comprise entre des limites admissibles. Applications courantes.A method of reducing the rise experienced, upon prolonged exposure to water or water vapor, of the dielectric loss of an underwater telecommunication coaxial cable in which a dielectric surrounds an inner conductor. At least the outer region of the dielectric of the cable is maintained at a temperature chosen between 40 and 90 degrees C for a period of time chosen, this time being short enough and the temperature moderate enough so that the performance of the cable is only affected no degradation or between acceptable limits. Common applications.
