Abstract
The utility model relates to a reinforced fiber composite links up ground wire which includes an electrical soft aluminum stranded wire which is used as a conductor. The electrical soft aluminum stranded wire is provided with stainless steel pipe optical units, and the inside of the electrical soft aluminum stranded wire is provided with a carbon fiber composite reinforcing core. The outside of the electrical soft aluminum stranded wire is coated with an insulating layer and a sheath. A flame retarding material is filled between the insulating layer and the sheath. The reinforced fiber composite links up ground wire allows the operating temperature to be increased above 180 DEG C for a long time, and improves the tensile capacity to 2400Mpa. At the same time, the reinforced fiber composite links up ground wire has the functions of communication, alarm, information feedback, and the like, and has the flame retarding property, so the reinforced fiber composite links up ground wire can effectively prevent the fire hazard caused by the cable fire.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, relates in particular to a kind of optoelectronic composite cable that can be fire-retardant.
Background technology
As everyone knows, conventional aerial insulated cable adopts copper stranded conductor, aluminium stranded conductor, aluminium alloy stranded conductor, steel reinforced aluminium conductor etc. as conductor usually, and the extruded insulation layer constitutes outside conductor; Wherein the tensile strength properties index of steel reinforced aluminium conductor conductor is best, can realize 1240Mpa-1410Mpa, but in the rural area, mountain area, the utilizable air corridor in forest zone reduce gradually; Shaft tower is apart from increase; The circuit ecological deterioration, circuit tension force strengthens, the corresponding increasing of sag; Requirement to circuit tensile strength significantly improves, and conventional aerial insulated cable can't bear; And insulating barrier adopts polyvinyl chloride, polyethylene, crosslinked polyethylene etc. usually; What wherein insulation property and temperature resistant grade were the highest is crosslinked polyetylene insulated; The long-term operating temperature that allows also is merely 90 ℃; Still can't satisfy the requirement that big load circuit uses, the aerial insulated cable that prior art is produced does not have communication function simultaneously; So original aerial insulated cable on function, lay on the environment, all can't satisfy electric power system demand under the new situation on temperature resistant grade and the current capacity, particularly can't satisfy of the requirement of the strong intelligent grid of nation-building to novel overhead transmission line.
Because the electric wire that natural calamity or artificial destruction cause is on fire, thus the fire quantity that causes also in continuous increase, at present commercially available cable-flame retardant performance is not strong, can not play good effect at the initial stage on fire.
The utility model content
The utility model technical problem to be solved is to overcome the deficiency of above-mentioned prior art, and a kind of reinforced optical fiber combined through earth wire is provided.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of reinforced carbon fiber optoelectronic composite cable; Comprise the soft aluminium stranded conductor of electrician as conductor; In the soft aluminium stranded conductor of electrician, insert stainless steel tube optical unit; Be provided with the compound strengthening core of carbon fiber in the soft aluminium stranded conductor of electrician, soft aluminium stranded conductor outside coated insulation layer of electrician and sheath are filled fire-retardant thing between insulating barrier and sheath.
Described fire-retardant thing is halide and the metal oxide that contains halogen.
Described insulating barrier is processed by polyether sulfone, and thickness is 1 ~ 2mm.
The compound strengthening core of described carbon fiber is by many stranded the processing of fine carbon.
The utility model will allow operating temperature to bring up to more than 180 ℃ for a long time, and resistance to tension is brought up to 2400Mpa, have functions such as communication, warning, feedback information simultaneously, have flame-retarding characteristic simultaneously, can effectively prevent the fire that causes owing to cable is on fire.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Embodiment
As shown in Figure 1; A kind of reinforced carbon fiber optoelectronic composite cable; Comprise the soft aluminium stranded conductor 2 of electrician, in the soft aluminium stranded conductor 2 of electrician, insert stainless steel tube optical unit 6, be provided with the compound strengthening core 1 of carbon fiber in the soft aluminium stranded conductor 2 of electrician as conductor; The soft aluminium stranded conductor of electrician 2 outsides coat the insulating barrier 3 and sheath 4 that the thickness of being processed by polyether sulfone is 1 ~ 2mm, between insulating barrier 3 and sheath 5, fill fire-retardant thing 4.Fire-retardant thing is halide and the metal oxide that contains halogen.
