Embodiment Construction

[0016] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, a reinforced aluminum alloy compression cable of the present invention includes a tubular aluminum alloy conductor 3, and a carbon fiber composite reinforcing core 1 is arranged at the center of the tubular aluminum alloy conductor 3, so that the tensile strength of the aluminum alloy cable itself is increased to The copper conductors of the same cross-section are fairly level, which effectively solves the problem of the cable being broken; a thin copper strip 2 is provided between the carbon fiber composite reinforcing core 1 and the tubular aluminum alloy conductor 3; an insulating layer is extruded outside the tubular aluminum alloy conductor 3 4. A single wire layer formed by winding multiple conductive single wires 5 in parallel is wound outside the insulating layer 4; a buffer layer 6 and an outer sheath 8 are wrapped around the...

Abstract

The invention discloses a reinforced aluminium alloy compressive cable. The reinforced aluminium alloy compressive cable comprises a tubular aluminium alloy conductor; a carbon fibre composite reinforced core is arranged in the centre of the tubular aluminium alloy conductor; a thin copper strip is arranged between the carbon fibre composite reinforced core and the tubular aluminium alloy conductor; an insulation layer is wrapped outside the tubular aluminium alloy conductor in an extruded manner; a single-wire layer, which is formed by a plurality of conductive single wires in a parallel winding manner, is wound outside the insulation layer; a buffer layer and an outer sheath are lapped outside the single-wire layer; and a metal compressive tube is also arranged between the buffer layer and the outer sheath. The reinforced aluminium alloy compressive cable disclosed by the invention is high in compressive strength and mechanical strength, good in moisture resistance, sealing performance and flexibility, low in cost and long in service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to a reinforced aluminum alloy compression cable. Background technique [0002] As we all know, conventional aluminum alloy cables usually use AA8000 series aluminum alloy stranded wire as the conductor, and the insulation layer is extruded outside the conductor, while the traction strength of the aluminum alloy cable is 53MPa, which is far lower than the 70MPa of the copper conductor cable; Breakage occurs. [0003] In the prior art, the support frame is used to support the cable, and the coaxial cable is protected by adding a support frame, which has a certain effect, but increases the laying cost and time, and the cable itself has poor load-bearing performance, and it is inevitable during the construction process. The core of the cable is damaged due to careless operation. [0004] In recent years, cable companies have generally realized the shortcomings of this aluminum alloy cable itsel...
