Abstract (en)
A power cable for carrying heavy current is shaped as a flat cable (10) which can be folded together and retained as a substantially round cable. The cable is made of an insulating plastic material, in which a plurality of parallel, solid, electric conductors (12) are embedded at regular intervals. The cable according to the invention is characterised in that during the manufacturing process the cable is subjected to a deformation in such a manner that the flat cable has assumed the shape of a cylindrical spiral, and in such a manner that each of the solid conductors of the cable follows a cylindrical, helical course, where said deformation assists in maintaining a helical shape. The resulting cable (10) can be maintained in the coiled state by the spiralling while it is installed in a building. When a piercing module is to be mounted on the cable, the portion of the cable to be inside the piercing module is flattened by unfolding the spiralling. <IMAGE>
