Abstract

The utility model provides a OPGW optical cable, includes central reinforcement, around the loose sleeve pipe around central reinforcement, sets up at the intraductal optic fibre of pine cover, the intussuseption of pine sleeve pipe is filled with the fine cream that blocks water, and the aluminum pipe, aluminium -clad steel wire and aluminiumalloy wire, the inside insulating layer that is provided with of aluminum pipe, the inside cream that blocks water of packing of insulating layer, aluminium -clad steel wire sets up between aluminum pipe and aluminiumalloy wire, aluminium -clad steel wire and the fine and close contact of aluminiumalloy wire transposition. The utility model relates to an ingenious, through setting up an insulating layer in the aluminum pipe of optic fibre, can be when the short circuit takes place or suffers the thunderbolt for OPGW optical cable the circuit a large amount of damages of high temperature to optic fibre that stop thermal the time produce, the outside double -deck layer stranded type structure of aluminiumalloy wire and aluminium -clad steel wire that adopts of OPGW to stranding each other with the aluminum pipe, making whole OPGW optical cable's material and the even unanimity of structure, electric conductivity and fatigue resistance are better.

Description

A kind of OPGW Optical cable

Technical field

This utility model relates to a kind of OPGW optical cable, belongs to electric power optical cable technical field.

Background technology

OPGW optical cable refers to optical fiber to be placed in the ground wire of aerial high voltage power line, and in order to constitute the fiber optic communication network on transmission line of electricity, this version has ground wire and the dual-use function that communicates concurrently.OPGW optical cable sets up along with electric lines of force, has plurality of advantages such as can saving construction cost, reliability height, degree of safety height, life-span length, thus becomes the main separation transmission medium of communication of power system.But, when power circuit is short-circuited or OPGW optical cable is struck by lightning, outer layer aluminium alloy wire or aluminum-clad steel wire produce bigger heat, damage damaging property of optical fiber, the most then affect communication quality, heavy then cause optical fibre damage to interrupt.

Utility model content

For the problems referred to above, this utility model provides a kind of OPGW optical cable, its object is to: design the OPGW optical cable that a kind of heat resistance is good, intensity big, effectively internal optical fiber quality can be protected more to consolidate under the emergency case of short time.

Technical solution of the present utility model:

A kind of OPGW optical cable, including center reinforcement, it is centered around the Loose tube around the reinforcement of center, the optical fiber being arranged in Loose tube, it is filled with the fine cream that blocks water in described Loose tube, aluminum pipe, aluminum-clad steel wire and aluminium alloy wire, it is characterised in that: described aluminum pipe is internally provided with a thermal insulation layer, is filled with waterproof paste inside described thermal insulation layer, described aluminum-clad steel wire is arranged between aluminum pipe and aluminium alloy wire, aluminum-clad steel wire and the stranded dense contact of aluminium alloy wire.

Described reinforcement is carbon-fibre stiffeners or fiberglass reinforcement.

Described aluminum pipe is seamless aluminium tubing.

Described thermal insulation layer is glass fiber.

The beneficial effects of the utility model:

This utility model design is ingenious, by arranging a thermal insulation layer in the aluminum pipe of optical fiber, it is possible to stop high temperature to be damaged optical fiber OPGW optical cable is short-circuited or produces amount of heat by circuit when being struck by lightning when；OPGW is outside uses aluminium alloy wire and aluminum-clad steel wire bilayer layer-twisted type structure, and the most stranded with aluminum pipe, makes the material of whole OPGW optical cable and even structure consistent, and electric conductivity and fatigue performance are preferable.

Accompanying drawing explanation

Fig. 1: this utility model structural principle schematic diagram.

The most each icon is: 1 center reinforcement, 2 Loose tube, 3 optical fiber, 4 block water fine cream, 5 block water implant, 6 aluminum pipes, 7 thermal insulation layers, 8 aluminum-clad steel wires, 9 aluminium alloy wires.

Detailed description of the invention

With embodiment, this utility model is described further below in conjunction with the accompanying drawings:

A kind of OPGW optical cable, including center reinforcement 1, the Loose tube 2 being internally provided with optical fiber 3 is centered around around center reinforcement 1, Loose tube 3 is internally provided with the fine cream 4 that blocks water, being internally provided with a thermal insulation layer 7 at aluminum pipe 6, described thermal insulation layer is glass fiber thermal insulation layer, is internally provided with, at thermal insulation layer 7, the implant 5 that blocks water, have in the outside of aluminum pipe 6 and have aluminum-clad steel wire 8 consistent with aluminium alloy wire 9 mutual stranded dense contact formation even structure respectively, electric conductivity and fatigue performance preferable OPGW optical cable.

The above, it it is only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, although this utility model is disclosed above with preferred embodiment, but it is not limited to this utility model, any those skilled in the art, in the range of without departing from technical solutions of the utility model, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solutions of the utility model content, according to technical spirit of the present utility model, within spirit of the present utility model and principle, the any simple amendment that above example is made, equivalent and improvement etc., within all still falling within the protection domain of technical solutions of the utility model.

To sum up, this utility model accomplishes the end in view.
