Description
Technical field
This utility model relates to a kind of overhead insulating cable, belongs to technical field of cables.
Background technology
Along with urban population density increases, architecture ensemble, afforesting the contradiction of dense region and city net overhead transmission line, particularly tree, line contradiction is especially prominent.The problems such as the grid short circuit accident caused by aerial bare line and electric shock personal safety have caused the attention of power supply department, and overhead insulating cable is being used in urban distribution network, uses replacement aerial bare line.
At present, incity, city aerial cable is that multiply has the cable of spacing parallel lay-up to constitute mostly, and such to lay the area that takes up room bigger；Additionally, due to be separated absolute construction between stranded cable, per share length of cable is the longest, is unfavorable for carrying out stranded cable tying up, twining operations such as tying up.
Utility model content
The deficiency that this utility model exists for prior art, it is provided that a kind of overhead insulating cable, concrete technical scheme is as follows:
A kind of overhead insulating cable, including centrally located cable wire, cable tie and strapping tape, described cable wire includes zinc-plated steel core and insulating sheath, and insulating sheath is coated on the surface of zinc-plated steel core；Described cable tie includes three cables being parallel to each other, and is provided with band muscle between adjacent cable, connects by band muscle is fixing between three cables；Described cable includes conductive core, conductor shield, crosslinked polyetylene insulated layer, insulation screen, metal protection protector, weather-proof sheath; described conductor shield is coated on the surface of conductive core; crosslinked polyetylene insulated layer is coated on the surface of conductor shield; insulation screen is coated on the surface of crosslinked polyetylene insulated layer; metal protection protector is coated on the surface of insulation screen, and weather-proof sheath is coated on the surface of metal protection protector；The weather-proof sheath that described cable tie is coated in the surface of cable wire and cable tie is all tangent with the insulating sheath on cable wire, is filled with epoxy resin between cable tie and cable wire, connects by epoxy resin is fixing between left side and the right side of cable tie of cable tie；Described strapping tape is spirally wound on the outside of cable tie.
As the improvement of technique scheme, the outside of described band muscle is provided with the reinforcement that cross section is triangle, is integral type structure between reinforcement and band muscle.
As the improvement of technique scheme, described strapping tape includes two one metal wires and is coated on the protective layer outside tinsel, and the cross section of protective layer is the figure of eight.
Overhead insulating cable described in the utility model by carrying out boundling and being embedded a cable wire at its center by three cables, reduce the space between three cables, space, space is little, improves mechanical performance and the weather resistance of overhead insulating cable, reduces the erection spatial area of overhead insulating cable；Under the connection of band muscle, three separate cables define the cable tie of banding so that cable tie winds, is coated on the outside of cable wire, the processing of convenient built on stilts insulation cable and making more easily, reduces difficulty of processing, and implementation result is good.
Accompanying drawing explanation
Fig. 1 is overhead insulating cable structure schematic diagram described in the utility model；
Fig. 2 is cable tie structural representation described in the utility model；
Fig. 3 is strapping tape structural representation described in the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As depicted in figs. 1 and 2, Fig. 1 is overhead insulating cable structure schematic diagram described in the utility model, and Fig. 2 is cable tie structural representation described in the utility model.Described overhead insulating cable, including centrally located cable wire, cable tie and strapping tape 50, described cable wire includes zinc-plated steel core 11 and insulating sheath 12, and insulating sheath 12 is coated on the surface of zinc-plated steel core 11；Described cable tie includes three cables being parallel to each other, and is provided with band muscle 30 between adjacent cable, connects by band muscle 30 is fixing between three cables；Described cable includes conductive core 21, conductor shield 22, crosslinked polyetylene insulated layer 23, insulation screen 24, metal protection protector 25, weather-proof sheath 26; described conductor shield 22 is coated on the surface of conductive core 21; crosslinked polyetylene insulated layer 23 is coated on the surface of conductor shield 22; insulation screen 24 is coated on the surface of crosslinked polyetylene insulated layer 23; metal protection protector 25 is coated on the surface of insulation screen 24, and weather-proof sheath 26 is coated on the surface of metal protection protector 25；The weather-proof sheath 26 that described cable tie is coated in the surface of cable wire and cable tie is all tangent with the insulating sheath 12 on cable wire, it is filled with epoxy resin 40 between cable tie and cable wire, connects by epoxy resin 40 is fixing between left side and the right side of cable tie of cable tie；Described strapping tape 50 is spirally wound on the outside of cable tie.
Zinc-plated steel core 11 in cable wire mainly has support, improves the described flexible effect of overhead insulating cable, and zinc-plated steel core 11 protected by insulating sheath 12, and insulating sheath 12 is also more conducive to combine between cable wire and epoxy resin 40.With the combination between muscle 30 and weather-proof sheath 26, it is preferably integral type structure between band muscle 30 and weather-proof sheath 26, by one extrusion moulding between band muscle 30 and weather-proof sheath 26；Under the connection of band muscle 30, three separate cables constitute cable tie so that cable tie winds, is coated on the outside of cable wire more easily.Weather-proof sheath 26 in cable tie is all tangent with the insulating sheath 12 on cable wire, further reduces the internal clearance of described overhead insulating cable；Epoxy resin 40 not only has adhesive effect so that the left and right side of cable tie is formed sleeve-like structure by bonding respectively；Epoxy resin 40 also has excellent heat dispersion.
In order to reinforce band muscle 30 further, preventing band muscle 30 in the course of processing to be torn, the outside of described band muscle 30 is provided with the reinforcement 31 that cross section is triangle, is integral type structure between reinforcement 31 and band muscle 30.The reinforcement 31 of triangle also improves the rate of heat dispation that cable tie is outwards dispelled the heat, good heat dissipation effect.
So that strapping tape 50 be wound around time stress evenly, as it is shown on figure 3, Fig. 3 is strapping tape structural representation described in the utility model.Described strapping tape 50 includes two one metal wires 51 and is coated on the protective layer 52 outside tinsel 51, and the cross section of protective layer 52 is the figure of eight.Two one metal wires 51 have support, reinforcement effect, and cross section is that the protective layer 52 of the figure of eight makes strapping tape 50 winding layer of formation when being wound around finer and close, and often the space between circle strapping tape 50 is less, and winding effect is good, and winding mass is high.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
