ABSTRACT:
An optical cable structure for use in high-voltage environments comprised of a metal-free cable core having optical elements therein and a multi-layer sheath encasing the cable core with all the hollow spaces within the cable core and in the sheath being filled with a softened or plasticized cross-linked synthetic material selected from the group consisting of a polyurethane resin, an epoxy resin and a polyester resin and at least the outer layer of the multi-layer sheath is composed of a creep-resistant material based on a compound selected from the group consisting of a polyolefin, such as a polyethylene or polypropylene, a polyurethane, a polyester or a polyester-elastomer. Such an optical communication cable structure is stabile in high-voltage environments and can be laid as desired adjacent structures carrying high voltage and can, for example, be suspended at overhead voltage lines.
