Abstract
The utility model solves problems of relatively large mass and high mounting cost existing in a cable in the prior art. The utility model provides a vertically-mounted cable. The vertically-mounted cable comprises a copper core and an insulation layer wrapped outside the copper core and further comprises a filling material, an inner protection layer, an outer protection layer and an armored layer, wherein multiple conductors and the filling material are arranged in the inner protection layer, the inner protection layer is externally wrapped in the armored layer, the armored layer is externally wrapped in the outer protection layer, the armored layer comprises aluminum alloy filaments and reinforced carbon fiber filaments, and the reinforced carbon fiber filaments are uniformly distributed among the aluminum alloy filaments. According to the vertically-mounted cable, the armored layer employs the aluminum alloy filaments to greatly reduce the mass of the cable; the reinforced carbon fiber filaments are uniformly distributed among the aluminum alloy filaments of the armored layer, so the mass of the cable is smaller, tensile strength is greatly improved, long-time use stability is guaranteed, and service life is prolonged. The vertically-mounted cable is advantaged in that great reduction of the cable mass and convenient arrangement and mounting of the cable are realized while tensile strength of the cable can be guaranteed.
Description
Technical field
The utility model relates to power cable technical field, specially refers to a kind of at right angle setting cable.
Background technology
The power cable that the electricity of skyscraper delivery at present uses is generally steel-tape armouring or wire armoring type power cable, there is good pull resistance, but in skyscraper delivery electric system, because the vertically disposed length of cable is generally longer, the conductor quality of cable adds steel-tape armouring or steel wire armoured quality can be very large, can be very high to the stiff end requirement of strength of cable, the stiff end of setting is also more, increases installation cost and is unfavorable for the installation of cable.Obviously, existing power cable exists the problems such as the large and installation cost height of quality.
Summary of the invention
Exist the problems such as the large and installation cost height of quality for solving existing power cable, the utility model proposes a kind of at right angle setting cable.
The utility model at right angle setting cable, comprise conductor, conductor comprises copper core and is wrapped in the insulating barrier outside copper core, also comprise packing material, sheath, outer jacket and armour, described conductor is multiply, packing material is filled between multiply conductor, and conductor and packing material are all arranged in sheath; Described armour is wrapped in outside sheath, and outer jacket is wrapped in outside armour; Described armour comprises aluminum-alloy wire and carbon fiber reinforced wire, and carbon fiber reinforced wire is uniform to be arranged between aluminum-alloy wire.
Further, the utility model at right angle setting equals the ratio of the maximum bearing tension of cable total weight and carbon fiber reinforced wire by the quantity of the carbon fiber reinforced wire of cable.
Further, the utility model at right angle setting is wrapped on sheath surface with aluminum-alloy wire and the carbon fiber reinforced wire of cable.
Further, the utility model at right angle setting is annular with the armour of cable.
The utility model at right angle setting owing to adopting aluminum-alloy wire to replace original steel band or steel wire, significantly reduces cable quality with the armour of cable; Also, because the aluminum-alloy wire at armour is evenly provided with carbon fiber reinforced wire, not only make cable quality less, and significantly improved tensile strength, guarantee the stability of cable in the long-term use procedure of at right angle setting, extend cable useful life.The utility model at right angle setting is in the tensile strength while that ensures cable, significantly to reduce the quality of cable with the useful technique effect of cable, facilitates the layout of cable to install.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of cable for the utility model at right angle setting.
In accompanying drawing 1,1 is copper core, and 2 is insulating barrier, and 3 is packing material, and 4 is sheath, and 5 is aluminum-alloy wire, and 6 is carbon fiber reinforced wire, and 7 is outer jacket.
Below in conjunction with the drawings and specific embodiments, the utility model at right angle setting is further described with cable.
Embodiment
Accompanying drawing 1 is the structural representation of cable for the utility model at right angle setting, and in accompanying drawing 1,1 is copper core, and 2 is insulating barrier, and 3 is packing material, and 4 is sheath, and 5 is aluminum-alloy wire, and 6 is carbon fiber reinforced wire, and 7 is outer jacket.As accompanying drawing 1, the utility model at right angle setting cable, comprise conductor, conductor comprises copper core 1 and is wrapped in the insulating barrier 2 outside copper core 1, also comprise packing material 3, sheath 4, outer jacket 7 and armour, described conductor is multiply, and packing material 3 is filled between multiply conductor, and conductor and packing material 3 are all arranged in sheath 4; Described armour is wrapped in outside sheath 4, and outer jacket 7 is wrapped in outside armour; Described armour comprises aluminum-alloy wire 5 and carbon fiber reinforced wire 6, and carbon fiber reinforced wire 6 is uniform to be arranged between aluminum-alloy wire 5.
The utility model at right angle setting equals the ratio of the maximum bearing tension of cable total weight and carbon fiber reinforced wire by the quantity of the carbon fiber reinforced wire 6 of cable, relational expression is n=MG/F, in formula: " n " is the quantity of carbon fiber reinforced wire 6, unit is " root "; " M " is cable gross mass, and unit is " Kg "; " G " is universal gravitational constant; " F " is the maximum bearing tension of carbon fiber reinforced wire, and unit is further to alleviate cable quality for " N " principle, strengthens the tensile strength of cable; The utility model at right angle setting is wrapped on sheath 4 surfaces with aluminum-alloy wire 5 and the carbon fiber reinforced wire 6 of cable, its role is to protect conductor.
In the time of concrete use, the utility model at right angle setting can be multiply copper core 1 with the conductor in cable, copper core 1 is coated with insulating barrier 2, the hinge joint of multiply conductor is arranged in sheath 4, gap is provided with packing material 3, effect is fixed conductor, avoid conductor bending to fracture, sheath 4 surfaces are also provided with annular armour, in armour, be provided with aluminum-alloy wire 5 and carbon fiber reinforced wire 6, the quantity of carbon fiber reinforced wire 6 is passed through calculated relationship: the ratio meter of the maximum bearing tension of cable total weight and carbon fiber reinforced wire calculates the quantity of carbon fiber reinforced wire 6, the aluminum-alloy wire 5 and the carbon fiber reinforced wire 6 that in the time of cable under tension and bending, in armour, arrange, reliable tensile strength can be provided, and alleviate the total quality of cable, finally also be provided with outer jacket 7 at annular armour outer surface, effect is cable to reinforce, improve the antijamming capability of cable.When installation, because the utility model at right angle setting significantly reduces by the quality of cable, therefore reduce the stiff end requirement of strength to fixing the utility model cable, reduced the installation difficulty of the utility model at right angle setting cable.
The utility model at right angle setting owing to adopting aluminum-alloy wire 5 to replace original steel band or steel wire, significantly reduces cable quality with the annular armour of cable; Also, because the aluminum-alloy wire 5 at armour is evenly provided with carbon fiber reinforced wire 6, not only make cable quality less, and significantly improved tensile strength, guarantee the stability of cable in the long-term use procedure of at right angle setting, extend cable useful life.The utility model at right angle setting is in the tensile strength while that ensures cable, significantly to reduce the quality of cable with the useful technique effect of cable, facilitates the layout of cable to install.
