Abstract

Procédé et dispositif d'application d'un isolement en matière synthétique réticulable et vulcanisable. Le procédé permet l'introduction d'un mélange à réticuler de façon accélérée par des additifs, par un procédé de réticulation travaillant à peu près sans pression, sans prendre en considération les difficultés pour le stockage d'une solution déjà complètement combinée. Pour permettre cela, on évite la combinaison (fusion et granulation) du mélange dans une étape particulière de travail au moins partiellement, lorsqu'on produit la fusion, le mélange et l'homogénéisation dans une étape de travail avec l'application de la gaine isolante sur le conducteur ou sur le câble. Le nouveau procédé est approprié de façon surprenante pour la réticulation dite au bain de sel selon laquelle l'isolement juste extrudé est conduit à travers une masse fondue de sel ou également de métal comme véhiculeur thermique.Method and device for applying an insulation made of crosslinkable and vulcanizable synthetic material. The process allows the introduction of a mixture to be crosslinked in an accelerated manner by additives, by a crosslinking process working almost without pressure, without taking into account the difficulties for the storage of a solution already fully combined. To allow this, the combination (melting and granulation) of the mixture is avoided in a particular working step at least partially, when the melting, mixing and homogenization is produced in a working step with the application of the sheath. insulation on the conductor or on the cable. The new process is surprisingly suitable for the so-called salt bath crosslinking in which the just extruded isolation is carried out through a molten mass of salt or also of metal as a thermal carrier.
