ABSTRACT OF THE DISCLOSURE A process and apparatus for the vulcanization of the insulation of an electric cable in which the cable core with the insulation thereon are passed through a tube filled with a liquid having a specific weight substantially equal to the specific weight of the insulation. The section of the tube nearer the entrance end is supplied with degassed liquid at vulcanizing temperature and the following section is supplied with degassed liquid at a temperature for cooling the insula- tion, and because the liquid has different viscosities at the two temperatures, a liquid interface is produced between the two portions which interface is maintained during the vul- canizing of the insulation. During the vulcanizing of the insulation, a portion of the liquid in at least one section is removed and treated to remove vulcanization products.
