Aluminum alloy conductor coaxial electric unit type photoelectric hybrid cable

Abstract

The invention belongs to the technical field of wires and cables, and particularly relates to an aluminium alloy conductor coaxial electrical unit type optical power composite cable. The aluminium alloy conductor coaxial electrical unit type optical power composite cable consists of a cable core, a shielding layer (12) coated outside the cable core in an overlapping manner, and an outer sheath (13) extruded and coated outside the shielding layer in a semi-extruding process manner; rip cords (11) are arranged between the outer gap of the cable core and the shielding layer; and the cable core comprises optical cable units and power line units. The aluminium alloy conductor coaxial electrical unit type optical power composite cable is characterized in that the cable core is formed by an inner layer unit and an outer layer unit positioned outside the inner layer unit. The aluminium alloy conductor coaxial electrical unit type optical power composite cable has the beneficial technical effects of excellent corrosion resistance, light weight, low price, good creep resistance, no relaxation phenomenon of a joint at a low temperature, high shielding performance, excellent lightning resistance, good bending performance, capability of achieving one path of power supply by a single coaxial power line, and the like.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, in particular to an aluminum alloy conductor coaxial electric unit type photoelectric hybrid cable. Background technique [0002] With the rapid development of the communication industry, the use of optical cables, photoelectric composite cables, and photoelectric hybrid cables is increasing. The conductors in the currently used photoelectric hybrid cables mainly use copper conductors and aluminum conductors.

[0002] With the rapid development of the communication industry, the use of optical cables, photoelectric composite cables, and photoelectric hybrid cables is increasing. The conductors in the currently used photoelectric hybrid cables mainly use copper conductors and aluminum conductors. Copper conductors have poor corrosion resistance and heavy weight. , expensive and other characteristics; aluminum conductors have poor creep resistance due to their large elongation, and cannot avoid the problem of loose joints at low temperatures; the current photoelectric hybrid cables are not compatible with high shielding performance and excellent lightning protection impact performance, low weight, and high bending performance; and in the current photoelectric hybrid cable, when providing power supply, one power supply needs to provide two wires, which is quite troublesome and affects the construction efficiency.
