Title (EN) A METHOD FOR VULCANIZING AN INSULATING LAYER OF AN ELECTRICAL CABLE
(FR) METHODE POUR VULCANISER UNE COUCHE ISOLANTE D"UN CABLE ELECTRIQUE
Abstract: front page image
(EN)A method for vulcanizing an insulating layer of an electrical cable. In a continuous process for manufacturing an electrical cable, which comprises an electrically conductive non-metallic layer extruded outside and preferably simultaneously with an electrically insulating layer, a method of vulcanizing the insulating layer comprises passing the cable (3) through a gas-filled pressure chamber (1) in which it is supplied with heat for vulcanizing the insulating layer, the heat being supplied completely or partly in the form of heat due to electrical resistance heating generated by electrical energy transferred to the conductive layer. In one example, the electrical energy is transferred to the conductive layer by means of at least one electrode (2, 4, 5 or 7 to 10) making contact against the layer. Alternatively, the electrical energy could be transferred in a capacitive way, or magnetically by generating eddy currents in the conductive layer.
(FR)La methode s"applique a un procede continu de fabrication d"un cable electrique qui comprend une couche non metallique, conductrice de l"electricite, extrudee a l"exterieur et de preference en simultaneite avec une couche isolante de l"electricite. La methode de vulcanisation de la couche isolante comprend le passage du cable (3) a travers une chambre (1) remplie de gaz sous pression, dans laquelle on amene de la chaleur pour la vulcanisation de la couche isolante. Cette chaleur peut etre totalement ou partiellement produite par resistance electrique et resulter de l"echauffement provoque par l"energie electrique amenee a la couche conductrice. Dans un exemple, l"energie electrique est amenee a la couche conductrice au moyen d"au moins une electrode (2, 4, 5 ou 7 a 10) mise en contact avec la couche. En remplacement, l"energie electrique pourrait etre amenee par voie capacitive ou magnetique par generation de courants tourbillonnaires dans la couche conductrice.
