Abstract
The invention relates to wires and cables and particularly relates to an aerial insulated cable which comprises three cables, wherein each of the three cables comprises a conductor; the conductor is coated with a shielding layer; the shielding layer is coated with an insulation-sheath composite layer; the three cables are arranged in an inverted-triangle manner; and two cables are positioned above in parallel, and the third cable is positioned below. The aerial insulated cable also comprises a steel rope, wherein the rope comprises a rope core; the rope core is coated with a protection jacket; the rope is positioned above the upper two cables and is tangential to the surfaces of the upper two cables; and a coating belt is wound outside the rope and three cables. The aerial insulated cable provided by the invention is a bundled aerial cable and has the advantages of space saving and tidy wiring; through the rope, the overall strength is improved; and three conductors are fixed in the coating belt as a whole, relative shaking of two adjacent cables is avoided, and thus the cable cross-linking caused by relative shaking is prevented.
Description
Technical field
The present invention relates to electric wire, more particularly to aerial insulated cable.
Background technology
At present, with the high speed development of urban construction, domestic one, tier 2 cities all in the transformation for carrying out old town, to carry
The beautification in high city and the traffic convenience of resident.As many buildings can not be destroyed, so needing the occupancy of auxiliary equipment
Space is compressed.In view of just there is complicated cable old town originally, therefore how on the basis for not changing original cable
On, workman and the research staff of routing field is annoying using the small gap between original cable again stringing.Therefore, city
Stringing field needs to develop a kind of saving space and connect up clean and tidy aerial cable in a hurry.
Content of the invention
The technical problem to be solved in the present invention be in order to overcome aerial cable of the prior art to take up room big and cloth
The blowzy defect of line, provides a kind of beaming type aerial cable, and the beaming type aerial cable has to be saved space and connect up whole
Clean advantage.
The present invention is to solve above-mentioned technical problem by following technical proposals：
Aerial insulated cable, including three of the cables, described three of the cables, include conductor respectively, conductor is coated with screen layer,
Screen layer is coated with insulation and sheath composite bed；Described three of the cables assumes inverted triangle arrangement, and two cables are located at side by side
With top, three of the cables is positioned at lower section；Also include the strand cable of a steel, described strand cable includes strand cable core, outside strand cable core
It is coated with protective case；The top of described strand cable two cables located above, and tangent with two cable surfaces above；Described
Clad strip is wound with outside strand cable and three of the cables.
Suspension rod is also associated with below described strand cable, and described downrod lower end connects two pressure pins.Described pressure pin is symmetrical
The both sides of guide rod are distributed in, between described suspension rod two cables located above, two above held respectively by described pressure pin
Cable.
The aerial insulated cable that the present invention is provided, is a kind of beaming type aerial cable, space and connects up whole with saving
Clean advantage, and bulk strength is improve by strand cable, three conductors are integrally attached in clad strip, adjacent two cables
Between relative rocking will not also occur, it is to avoid cable is linked to together because of relative rocking.
Description of the drawings
Fig. 1 is the aerial insulated cable cross-sectional view of the present invention.
Specific embodiment
The specific embodiment of the present invention is described below in conjunction with the accompanying drawings.
As shown in figure 1, aerial insulated cable, including three of the cables, described three of the cables, include conductor 2, conductor respectively
2 are coated with screen layer 6, and screen layer 6 is coated with insulation and sheath composite bed 7；Described three of the cables assumes inverted triangle row
Row, two cables be located at side by side with top, three of the cables is located at lower section；Also include the strand cable of a steel, described strand cable
Including strand cable core 1, strand cable core 1 is coated with protective case 5；The top of described strand cable two cables located above, and with above
Two cable surfaces are tangent；Clad strip 8 is wound with outside described strand cable and three of the cables.
Inverted triangle arranges cable, can improve overall tensile strength, especially by strand cable, strand cable two ends is fixed taut
Directly, cable weight can be undertaken, and it is sagging because of deadweight to reduce cable.
Suspension rod 3 is also associated with below described strand cable, and described 3 lower end of suspension rod connects two pressure pins 4.Described pressure pin 4
The both sides of guide rod 3 are symmetrically distributed in, between described suspension rod 3 two cables located above, described pressure pin 4 is held above respectively
Two cables.
By pressure pin 4, two cable weight supports above are supported on strand cable, reduce the load of clad strip 8, only below
A piece cable is carried by clad strip 8.Improve 8 service life of clad strip.
