Abstract
The utility model discloses a self-supporting eight-shaped cable which comprises a first outer sheath and a second outer sheath, the axes of the first outer sheath and the second outer sheath are parallel, and the first outer sheath and the second outer sheath are connected with each other by a connection rib, any cross section of the first outer sheath, the second outer sheath and the connection rib is eight-shaped, a suspension line is contained in the first outer sheath, a plurality of leads are contained in the second outer sheath, insulating layers are coated on the outer walls of the leads, and a cable core wrapping belt and a shielding layer are sequentially wound between the leads and the second outer sheath from inside to outside. Due to additional arrangement of the suspension line parallel to a traditional cable, the self-supporting eight-shaped cable does not need extra cables when being aerially erected, thus lowering application cost, being convenient to install, shortening about half of original installation working hours, and being suitable for popularization and use in aerially erecting cables.
Description
Technical field
The utility model relates to a kind of cable, particularly, and a kind of self-bearing type " 8 " font cable.
Background technology
In the prior art, cable of a great variety, diverse in function for the cable that sets up, generally need be come the support cable with the cable of supplemental support in the air, just makes application cost strengthen, and inconvenience is installed.
The utility model content
The purpose of this utility model provides a kind of self-bearing type " 8 " font cable.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of self-bearing type " 8 " font cable, comprise first oversheath and second oversheath that axial line parallels, be connected by dowel between described first oversheath and described second oversheath, described first oversheath, arbitrary cross section of described second oversheath and described dowel is " 8 " font, contain messenger wire in described first oversheath, contain some leads in described second oversheath, the outer wall bag of each described lead is provided with insulating barrier, is surrounded with cable core band and screen from inside to outside successively between these described leads and described second oversheath.
Preferably, described first oversheath, described second oversheath and described dowel are the one extrusion moulding.
Preferably, described screen is two-sided aluminium-plastic tape.
Preferably, described cable core band is the non-hygroscopic insulating tape.
The beneficial effects of the utility model are: by adding the messenger wire that parallels with traditional cable, make when aloft setting up, no longer need the cable that adds, reduced application cost, and be convenient to install, installation work-hour shortened original near half, be adapted at promoting the use of in the sky frame cable.
Description of drawings
In the accompanying drawing: 1, first oversheath; 2, second oversheath; 3, dowel; 4, messenger wire; 5, lead; 6, insulating barrier; 7, cable core band; 8, screen.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is done following detailed description the in detail:
As shown in Figure 1, self-bearing type of the present utility model " 8 " font cable, comprise first oversheath 1 and second oversheath 2 that axial line parallels, be connected by dowel 3 between first oversheath 1 and second oversheath 2, first oversheath 1, arbitrary cross section of second oversheath 2 and dowel 3 is " 8 " font, contain messenger wire 4 in first oversheath 1, contain some leads 5 in second oversheath 2, the outer wall bag of each lead 5 is provided with insulating barrier 6, be surrounded with cable core band 7 and screen 8 from inside to outside successively between these leads 5 and second oversheath 2, first oversheath 1, second oversheath 2 and dowel 3 are the one extrusion moulding, screen 8 is two-sided aluminium-plastic tape, cable core band 7 is the non-hygroscopic insulating tape, wherein, lead 5 is solid annealed copper wire, and insulating barrier 6 is that high density polyethylene (HDPE) insulating barrier 6, the first oversheaths 1 and second oversheath 2 are black low-density or LLDPE.
The utility model makes when aloft setting up by adding the messenger wire that parallels with traditional cable, no longer needs the cable that adds, reduced application cost, and be convenient to install, installation work-hour shortened original near half, be adapted at promoting the use of in the sky frame cable.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
