Abstract
A stranded filament bundle is coated with a cross-linking plastic that contains carbon black followed by enveloping in a plastic that cross-links in the presence of moisture. The inner coating will cross-link either when the outer layer cross-links by water treatment; or by conduction of heat in the extruder for the outer layer; or by microwave heating.
