Combined insulated wire for overhead distribution power lines with voltage up to 1 kV 50 Hz optical modules

摘要

The claimed invention relates to the field of electrical engineering, namely to manufacturing of electric cables and optical cables. Combined wire for overhead distribution lines comprising conductive wires made of aluminum wires stranded together, compacted isolated thermoplastic or cross-linked polyethylene, or the polymer compositions flame retardant, wherein the inserted at least one optical module, the optical module is configured with a number of fibers of 1 to 48 pieces, the optical module sheath is made of a mechanically durable weatherable polymeric material between the optical module and the external Obolo chkoy longitudinally overlapping edges molded alumopolymer ribbon with an aluminum foil thickness of not less than 80 microns, the optical module is integrated in the electrical conductor. introduced suspension cable made of wires of aluminum alloy or aluminum wires reinforced with galvanized steel wire, insulated conductive wires are twisted around the carrier rope optical module is twisted together with the insulated conductive wires around the carrier rope Combined occasion developed and industrialized is mastered of "Sevkabel", St. Petersburg, Russia and JSC "Sevkabel Optic", Saint-Petersburg, Russia.
