Abstract

Procedure for the manufacture of electrical cables for telecommunications, insulated and protected with plastic materials, more particularly telephone, telegraph or mixed cables, and pieces of cable for radio or television signals at high or ultra high frequencies, of the normal or coaxial types, and for underground, aerial or underwater installations, in which the insulation or coating of the conductors is obtained from solid polymers or mixtures consisting predominantly of them, characterized in that the individual conductors, or the coaxial pairs of conductors, are insulated and/or or coated with an insulation consisting of linear, highly crystalline, high propylene polymers, or in a mixture predominantly containing such polymers.
