  • Method and device for manufacturing an insulative material cellular insulator around a conductor and coaxial cable provided with an insulator of this kind
    Patent number: 5922155
    Abstract: A method of manufacturing an insulative material cellular insulator around a conductor, the insulator having a longitudinal passage in which the conductor is housed and closed cells extending longitudinally and separated from each other by radial walls, includes the following operations: the insulative material in the viscous state is extruded to impart the required shape to it to form the cells, the insulative material shaped in this way is applied to the conductor, and the insulative material is cooled to obtain the insulator. The insulative material is applied to the conductor at a distance from the exit of the shaping device such that the material is drawn down sufficiently for the walls of the cells not to be thinned without pressurizing the cells.
