OVERHEAD CABLE FOR THE TRANSMISSION OF LOWâ“VOLTAGE AND MEDIUMâ“VOLTAGE ELECTRIC POWER AND DIGITAL SIGNAL, ALUMINUM ALLOY CONCENTRIC CONDUCTORS WITH A FIBERâ“OPTIC CABLE INSIDE AND DRAWN WIRE TREATMENT PROCESS.

摘要

An overhead cable for the transmission of low- voltage and medium-voltage energy and digital signals, comprising a central fiber-optic cable, surrounded by a protective covering of the central fiber-optic cable and around such protective covering of such fiber optics by at least an aluminum alloy layer for the transmission of low-voltage and medium-voltage electric power or neutral wire and the covering thereof, where at least one aluminum alloy layer comprises a 6101 aluminum alloy wire that has been heat treated, submitting the same to a temperature within a range of 260 and 300°C and a treatment process for the aluminum alloy drawn wire.
