ABSTRACT:
The invention relates to a method of manufacturing a cable. In the cable, the conductors are surrounded entirely or partly by synthetic resin supporting elements. In order to avoid shrinkage of the supporting elements, and hence extra loads on cable at high temperatures, the supporting elements are preshrunk before assembly of the cable. The elements are preshrunk by heating a temperature just below the softening temperature of the synthetic resin in question, maintaining them at this temperature, and then cooling them. During the heating process, the strength elements are mounted in such a way that their contraction will not put them into tension.
