摘要
An apparatus for continuous curing (vulcanization) of elongated products, such as cables comprising a conductor surrounded by a mantle of a crosslinkable material. The apparatus comprises a curing tube through which the cable is passed longitudinally. The curing tube comprises a heating zone in which the cable is subjected to heating for heating the cable to curing temperature in a pressurized gas atmosphere and a subsequent cooling zone in which the cured cable is subjected to cooling. The curing tube is coupled to at least one electric currency source so that the wall of the curing tube is heated due to the electric resistance of the wall material to form within the heating zone a heated mantle uniformly surrounding the cable and radiating heat thereto.
