Abstract

The utility model discloses a high -power optic fibre compound control cable of strenghthened type includes inner conductor center enhancement core, buffer layer, cavity inner conductor, insulating layer, outer conductor and oversheath from inside to outside, the outer conductor form with a optical fiber unit and the combination of a control insulation core again after bearing wire and the winding of outer conductor conductive single wire interval by quantity is the same. The utility model discloses have very strong bear the weight of certainly strengthen the performance, the decay is little, the shielding is effectual, can play signal transmission and control action simultaneously.

Description

A kind of reinforced large-power optical fiber complex controll cable

Technical field

The utility model relates to electric wire field, is specifically related to a kind of reinforced large-power optical fiber complex controll cable.

Background technology

The world today steps into the information age, information has become the strategic resource of Economic development and unique production factors, with telecommunication network, computer, the present information transmission system and complete information service system that combine set up depending on multi-media terminals such as pictures, become the important symbol of a country or regional economy development degree. Optical Fiber Composite cable is a kind of important kind during information is transmitted, main be used as transmit by radio or receiving equipment antenna feeder and various communication, the machine intraconnections of electronics or be interconnected line. Concentric cable is made up of inner conductor layer, insulation layer, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer are very little, from carrying poor performance, especially when cable uses under not buried operating mode, owing to load-carrying properties are poor, cable own wt can make cable conductor break, and is also easily damaging tiny cable conductor when constructing simultaneously. Prior art dish adopts bracing frame to be supported by cable; concentric cable is protected by increasing the form of bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can because operation causes the problem that the core of cable damages accidentally in construction process.

Practical novel content

In order to overcome the deficiencies in the prior art, it is provided that a kind of have very strong strengthen performance from carrying, decay little, shield effectiveness good, can play the reinforced large-power optical fiber complex controll cable of signal transmission and control action kou simultaneously.

For achieving the above object, the utility model discloses a kind of reinforced large-power optical fiber complex controll cable, comprise conductor center strengthening core, buffer layer, hollow inner conductor, insulation layer, outer conductor and oversheath from inside to outside; Described outer conductor combines with a fiber unit and a control insulated wire cores after being wound around by the identical bearing metal silk of quantity and outer conductor conduction single line interval again.

Preferably, described strengthening core and bearing metal silk are galvanized steel wire.

Preferably, described fiber unit is made up of central optical fiber and the protection metal pipe that is set in outside optical fiber.

Preferably, described control insulated wire cores is made up of the control insulation layer controlling conductor and be extruded in outside control conductor.

Preferably, described outer conductor conduction single line is annealing copper wire, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 or metal cladding annealed copper conductor that cable is conventional, comprise the conductor of the multiply hard round copper wire composition of compacting pressing or the conductor of the soft round copper wire composition of the non-multiply pressed, preferentially select the 5 zinc-plated soft structure conductors of class.

Preferably, described insulation layer is made up of Low Density Polyethylene, high density polyethylene(HDPE) or radiant crosslinked polyethylene material.

Preferably, described outer jacket is made up of polythene material.

The beneficial effects of the utility model are:

The utility model has very strong reinforcement performance, the conductor center layer You Yigen center strengthening core of cable, interior conductor concentrate on the strengthening core of center by force, cable, in folding and unfolding winding process, protects interior conductor annealing copper wire, and not frangibility; Outer conductor is wound around by outer conductor galvanized steel wire, outer conductor annealing copper wire gap simultaneously, and when carrying, cable outer conductor each several part not only uniform force, also improves the tensile property of interior conductor annealing copper wire; Cable entirety is full symmetrical configuration, and copper wire and galvanized steel wire have function of shielding, and inner and outer conductor is in concentric position, the media that electromagnetic energy is confined between internal and external conductor, therefore has decay little, shielding properties height; Change the single structure of traditional cable, add fiber unit, control conductor, formation compound cable, effect and due characteristic that tradition wind energy cable is powered can be reached, signal source function can be provided again, also there is controlling functions, make it three and it is combined into one, change the unicity of traditional cable; With control conductor, it is possible to play signal transmission and control action kou simultaneously; Compared with prior art not increasing new reinforcing structure, the construction of cable is simple, and the outside diameter of cable is less, conveniently lays.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and only it is not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of the various equivalent form of value of the present utility model is all fallen within the application's claims limited range by those skilled in the art.

As shown in Figure 1, the utility model provides a kind of reinforced large-power optical fiber complex controll cable, comprises conductor center strengthening core 1, buffer layer 2, hollow inner conductor 3, insulation layer 4, outer conductor and oversheath 7 from inside to outside; Be provided with conductor center strengthening core 1 at the center of hollow inner conductor 3, however make cable inner conductor concentrate on the strengthening core of center by force, cable, in folding and unfolding winding process, protects interior conductor annealing copper wire, and not frangibility; Outer conductor controls insulated wire cores with two again after being wound around by the identical bearing metal silk 5 of quantity and outer conductor conduction single line 6 interval and combines, and pitch controls between 60-80mm, winding direction be left to; Described fiber unit is made up of central optical fiber 8 and the protection metal pipe 9 that is set in outside optical fiber; Described control insulated wire cores is made up of the control insulation layer 11 controlling conductor 10 and be extruded in outside control conductor, it is possible to play signal transmission and control action kou simultaneously.

Described outer conductor conduction single line 6 is annealing copper wire, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 or metal cladding annealed copper conductor that cable is conventional, comprise the conductor of the multiply hard round copper wire composition of compacting pressing or the conductor of the soft round copper wire composition of the non-multiply pressed, preferentially select the 5 zinc-plated soft structure conductors of class.

The above is only preferred implementation of the present utility model; it is noted that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also making some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
