ABSTRACT:
In curing an extruded insulation layer of an electric cable by passing the cable through a catenary curing tube, a cable restraining device 8 is disposed at or just prior to the exit end of the catenary tube 11 and serves to apply to the cable 10 a restraint to oppose forces (developed by the hydrostatic pressure of the curing fluid) which tend to extrude the cable through the exit end of the curing tube. In the example shown, the device 8 comprises a set of resiliently flexible cones 9 and a clamping arrangement 12, 13 which is adjustable to adjust the degree of restraints.
