Process for preparing an electrical cable comprising at least one conductor
and at least one layer of extruded insulating coating, which includes:
coating, by extrusion, the conductor with a polymeric composition
comprising a polyethylene, a radical initiator and at least one
unsaturated carboxylic acid of general formula (I) in free form:
##STR1##
in which:
R.sub.1 represents H or CH.sub.3 ;
n represents 0 or 1;
said unsaturated carboxylic acid being present in an amount of between
0.0006% and 0.25% by weight, said amount being expressed as the weight
content of --COOH groups relative to the total weight of the polymeric
composition;
heating the conductor thus coated so as to obtain cross-linking of said
polymeric composition.
