Abstract

The invention relates to a photoelectric combination cable, which comprises an optical unit, a feeder line unit and a center reinforcement. The photoelectric combination cable is characterized in that the optical unit is provided with a plurality of dual-core semi-tight tube optical fiber protection layers, dual-core full-chromatograph optical fibers are arranged in the dual-core semi-tight tube optical fiber protection layers, multiple strands of aramid fiber reinforced yarns are longitudinally wrapped outside the dual-core semi-tight tube optical fiber protection layers, stainless steel metal hoses are spirally wrapped on the outer parts of the multiple strands of aramid fiber reinforced yarns, polyurethane jackets are extruded on the outer parts of the stainless steel metal hoses to form protection layers, a copper conductor is arranged in the center of the feeder line unit, a plurality of insulation layers are arranged on the copper conductor, polyurethane jackets are arranged on the outer parts of the insulation layers to form protection layers, the outer diameter of the optical unit is equal to that of the feeder line unit, the optical unit, the feeder line unit and a filling rope are twisted around a non-metal center reinforcement, water-stopping yarns are filled in a gap of the cable core, a water-stopping band is arranged outside the water-stopping yarns and an outer jacket is arranged on the outer part of the water-stopping band. The photoelectric combination cable has the advantages of reasonable design, compact structure, good flexibility, high mechanical strength, weather resistance, pressure resistance, good heat resistance, excellent fire resistance, high safety and wide application range.

Description

technical field [0001] The invention relates to the technical field of cables with dual functions of optical signal transmission and power transmission, in particular to a photoelectric combination cable. Background technique [0002] In recent years, the network construction of triple play and quadruple play has been highly praised by experts, scholars and operators. For this reason, there have been various photoelectric composite cables of various structures. The photoelectric composite cable has its unique advantages: small outer diameter, light weight, small space occupation, only one laying of the line, convenient construction, saving power investment, reducing the impact of power outages, and shortening the construction period; existing cities and streets can be used The tower or pipeline resources can also be deployed in the shaft of the building, and can provide a variety of transmission technologies. The equipment has high adaptability, strong scalability, and a wi...
