Abstract

La présente invention concerne un système et un procédé de réticulation chimique rapide pour câble électrique, le système et le procédé étant destinés à améliorer les propriétés thermiques et électriques d'une partie revêtement formant la couche externe du câble électrique qui est moulé par extrusion par une extrudeuse. Plus spécifiquement, le système de réticulation chimique rapide comprend : une première chambre de vulcanisation ; une unité de refroidissement ; une seconde chambre de vulcanisation ; et une unité de réticulation. Un trou de réception est ménagé d'un coté de la première chambre de vulcanisation pour recevoir le câble électrique qui est moulé par extrusion par l'extrudeuse, et l'intérieur de la première chambre de vulcanisation est maintenu à une pression qui est supérieure à la pression d'air. L'unité de refroidissement est un tuyau dont un côté est couplé pour communiquer avec la première chambre de vulcanisation, et de l'eau de refroidissement est reçue sur l'intérieur du tuyau de manière à refroidir le câble électrique en le faisant passer par l'intérieur du tuyau. La seconde chambre de vulcanisation est une chambre couplée pour communiquer avec l'autre côté de l'unité de refroidissement et, comme la première chambre de vulcanisation, l'intérieur de la seconde chambre de vulcanisation est maintenu à une pression qui est supérieure à la pression d'air. L'unité de réticulation est un tuyau dont un côté est couplé pour communiquer avec la seconde chambre de vulcanisation et dont l'autre côté est couplé pour communiquer avec la première chambre de vulcanisation, et l'intérieur du tuyau est maintenu à un état de chauffage de manière à soumettre le câble électrique à une réticulation chimique en le faisant passer par l'intérieur du tuyau. Selon la présente invention, comme décrit ci-dessus, l'unité de refroidissement et l'unité de réticulation sont placées entre les chambres de vulcanisation agencées des deux côtés de manière à déplacer le câble électrique en va-et-vient vers les deux côtés des chambres de vulcanisation, ce qui permet de réduire au minimum une ligne d'installation de production et de réduire ainsi les coûts d'installation. De plus, le câble électrique à haute température qui est moulé par extrusion par l'extrudeuse est d'abord refroidi avant d'être soumis à une réticulation chimique et peut ainsi être réticulé à grande vitesse sans transformation du câble, ce qui permet d'obtenir un rendement de production accru. En outre, la taille des installations de production est réduite, et le câble électrique est d'abord refroidi avant une réaction de réticulation chimique, moyennant quoi le câble électrique est applicable dans divers types de fils électriques comprenant des fils électrique de faible capacité tels que des fils électriques d'automobile, des fils électriques d'intérieur, des lignes d'équipement, etc., et possède donc une large plage d'applicabilité.
