Description
Technical field
The utility model relates to a kind of power transmission line more particularly to a kind of optical fiber compound insulation power transmission lines.
Background technique
Overhead transmission line is usually bare wire, if using aerial bare wire in city, it appears not safe and corrosion-resistant
Property is poor, and service life is short.With the continuous development of urban construction, power transmission line is just gradually moving towards underground piping or along road direct-burried side
Formula, this just needs a large amount of insulated power line.Plastic insulation power transmission line: it is wrapped again outside the insulation of insulated electric conductor or insulated flexible cord
One layer of metal foil or braiding one metal wire layer constitute shielded layer.Insulated power line only has the simple function for transmitting electric power, gives city
The information transmission of transmission system, power scheduling etc. bring difficult and inconvenient.
Utility model content
In order to solve the above technical problems, the technical problem to be solved by the utility model is to provide a kind of optical fiber composite insulateds
Power transmission line.
A kind of optical fiber compound insulation power transmission line provided by the utility model, it includes aluminium Baogang center support, optical fiber list
Member, inner insulating layer, transmission of electricity metallic cable, water blocking layer, aramid fiber layer and oversheath, aluminium Baogang center support include one
Root center aluminum cald steel wire and Duo Gen axial direction aluminum cald steel wire, trisection is arranged with more axis on the circumferencial direction of center aluminum cald steel wire
To aluminum cald steel wire, fiber unit, the aluminium are arranged in the trisection space that is formed on the circumferencial direction of center aluminum cald steel wire
It is cased with inner insulating layer outside Baogang's center support, transmission of electricity metallic cable is surrounded with outside the inner insulating layer, the transmission of electricity metal twists
Water blocking layer, aramid fiber layer and oversheath are successively cased with outside line.
Further, packing is also filled in the trisection space formed on the circumferencial direction of center aluminum cald steel wire.
Further, being twisted between the aramid fiber layer and oversheath has more aluminum-alloy wires.
Further, the fiber unit includes multifiber and the stainless steel tube that is arranged in outside optical fiber.
Compared with prior art, the utility model has the beneficial effects that aluminium Baogang center support is arranged in power transmission line center, this
The aluminium Baogang center support reinforcing effect of kind triangle is good, can protect the fiber unit of the inside, reduces and squeezes, and also has optical fiber
Unit and transmission of electricity metallic cable, optical signal and transmission telecommunications number can be transmitted, integral transmission line, armouring effect is good, intensity compared with
Height, bearing capacity are larger.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1, aluminium Baogang center support, 11, center aluminum cald steel wire, 12, axial aluminum cald steel wire, 2, fiber unit,
21, optical fiber, 22, stainless steel tube, 3, inner insulating layer, 4, transmission of electricity metallic cable, 5, water blocking layer, 6, aramid fiber layer, 7, oversheath,
8, packing, 9, aluminum-alloy wire.
Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawing and specific embodiment is described in detail, this
Embodiment described in specification is only used for explaining the utility model, is not used to limit the utility model.
Shown in Fig. 1, the optical fiber compound insulation power transmission line of the utility model, it includes aluminium Baogang center support 1, optical fiber list
Member 2, inner insulating layer 3, transmission of electricity metallic cable 4, water blocking layer 5, aramid fiber layer 6 and oversheath 7, aluminium Baogang center support 1 are wrapped
A center aluminum cald steel wire 11 and Duo Gen axial direction aluminum cald steel wire 12 are included, trisection is arranged on the circumferencial direction of center aluminum cald steel wire 11
More axial aluminum cald steel wires 12 are shown, the aluminium Baogang center support reinforcing effect of this triangle is good, can protect the light of the inside
Fine unit 2 is reduced and is squeezed, and is arranged with fiber unit in the trisection space formed on the circumferencial direction of center aluminum cald steel wire 11
2, aluminium Baogang center support 1 is cased with inner insulating layer 3 outside, and transmission of electricity metallic cable 4,2 He of fiber unit are surrounded with outside inner insulating layer 3
Transmission of electricity metallic cable 4 exists simultaneously, and can transmit optical signal and transmission telecommunications number, successively be cased with resistance outside transmission of electricity metallic cable 4
Water layer 5, aramid fiber layer 6 and oversheath 7.The intensity of aramid fiber layer 6 is higher, and bearing capacity is larger.
Gap will necessarily be generated in cabling process, if these gaps are closely knit without material filling, the cable of cable
Core is unstable.Therefore, packing 8 is also filled in the trisection space formed on the circumferencial direction of center aluminum cald steel wire 11.
Being twisted between aramid fiber layer 6 and oversheath 7 has more aluminum-alloy wires 9.Armouring effect is good, increases intensity and tension
Property.
Fiber unit 2 includes multifiber 21 and the stainless steel tube 22 being arranged in outside optical fiber 21.
The optical fiber compound insulation power transmission line of the utility model has aluminium Baogang center support 1, the aluminium packet of this triangle
Steel center support reinforcing effect is good, can protect the fiber unit 2 of the inside, reduces and squeezes, fiber unit 2 and transmission of electricity metallic cable
4 exist simultaneously, and can transmit optical signal and transmission telecommunications number, integral transmission line, armouring effect is good, and intensity is higher, bearing capacity
It is larger.
