1. A cable article comprising:
a polyolefin composition comprising
from 20.0 wt % to 80.0 wt % of component T1) being an interpolymer of ethylene and less than 7 wt %, of a polymerizable comonomer selected from the group consisting of unsaturated esters and hydrolyzable silane monomers;
from 0.5 wt % to 5.0 wt % of a peroxide; and
from 20.0 wt % to 80.0 wt % of component T2) comprising
A) 5-35% by weight of a propylene homopolymer containing 5% by weight or less of a fraction soluble in xylene at 25° C. (XSA), or a propylene ethylene copolymer containing 90% by weight or more of propylene units; containing 10% by weight or less of a fraction soluble in xylene at 25° C. (XSA), both the amount of propylene units and of the fraction XSA being referred to the weight of A);
B) 20-50% by weight; of a copolymer of ethylene and a C3-C8 alpha-olefin containing from 0.1% to 20% by weight of alpha-olefin units and containing 25% by weight or less; of a fraction soluble in xylene at 25° C. (XSB), both the amount of alpha-olefin units and of the fraction XSB being referred to the weight of (B); and
C) 30-60% by weight of a copolymer of ethylene and propylene containing from 25% to 75% by weight of ethylene units and containing from 40% to 95% by weight of a fraction soluble in xylene at 25° C. (XSC), both the amount of ethylene units and of the fraction XSC being referred to the weight of (C);
the amounts of (A), (B) and (C) being referred to the total weight of (A)+(B)+(C), the sum of the amount of (A)+(B)+(C) being 100,
wherein the cable article is selected from the group consisting of cable insulation and cable jacketing.
