Use as an insulator of a cross-linkable olefinterpolymer composition stabilized for direct contact with copper and an untinned copper conductor coated with this composition.

摘要

Olefine polymer or copolymer insulation may be applied directly to untinned copper conductors and cross-linked in contact therewith without severe oxidation damage if the cross-linkage copolymer contains from 0.5 to 10 parts by weight of zinc sulphide.
