FIELD: manufacturing technology.

SUBSTANCE: invention relates to a cable, including a cross-linked cable, also to a method for production of a cable, more preferably, to production of a power cable. Cable includes a conductor enveloped by one or more layers, wherein at least one of the above said layers is made from a polymer composition, which contains polyolefin and an anion-exchange additive of hydrotalcite type in the amount from 0.000001 to less than 1 wt% with respect to the total weight of the polymer composition. Herewith polyolefin is an unsaturated polymer of ethylene of low density, which is selected from an unsaturated ethylene homopolymer of low density or an unsaturated ethylene copolymer of low density and one or more comonomers in an amount of at least 50 wt% with respect to the total weight of the polymer component(s) present in the polymer composition. Besides, the polymer composition, if necessary, additionally contains peroxide in the amount of less than 35 mmol -O-O-/kg of the polymer composition. Herewith the cable, probably, is ligated and then cross-linked.

EFFECT: obtained cable has low conductivity and good mechanical properties.
