Abstract

The utility model discloses an optical fiber composite overhead ground wire, which comprises an optical unit, a metal skeleton, a carbon fiber composite core and a conductor. The optical unit is embedded in the metal skeleton, the carbon fiber composite core is coated on the metal skeleton, and the conductor is plied on the outer surface of the carbon fiber composite core. The utility model has the following advantages that: as the carbon fiber composite core is used as the carrier to bear tensile force, the specification scope of the optical fiber composite overhead ground wire is expanded, and the weight of the optical fiber composite overhead ground wire is reduced to approximately one fourth of the original weight, while the intensity is improved twice of the original intensity, thereby the load on the wiring tower and the cost of laying installation are reduced, the installation period is greatly shortened, and the safety is improved.

Description

Optical Fiber composite overhead Ground Wire

Technical field

The utility model relates to a kind of electric wire, is a kind of Optical Fiber composite overhead Ground Wire specifically.

Background technology

According to the DL/T832-2003 standard, Optical Fiber composite overhead Ground Wire is made up of aluminum or aluminum alloy line, galvanized steel wire or aluminium-clad steel wire and light unit, wherein the aluminum or aluminum alloy line mainly plays the electric energy transmission, and galvanized steel wire or aluminium-clad steel wire mainly work to bear pulling force, light unit transmitting optical signal.Optical Fiber composite overhead Ground Wire is the combination of aerial condutor and light unit, because the restriction of structure, make that the Optical Fiber composite overhead Ground Wire of production heavy in section, big core number is very difficult, the core number that is optical fiber can not be too many, the sectional area of aluminum or aluminum alloy can not be too big, generally speaking, when being increased to 72 cores, the core number of optical fiber just is difficult to produce, and traditional Optical Fiber composite overhead Ground Wire has the characteristics of Heavy Weight, weak strength, causes increase, installation period prolongation and the fail safe of stringing iron tower load and laying installation cost low.

The utility model content

Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of in light weight, intensity is high, can reduce stringing iron tower load and laying installation cost, reduction of erection time, raising fail safe and the Optical Fiber composite overhead Ground Wire that can expand specification limit.

Technical scheme: in order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Optical Fiber composite overhead Ground Wire, comprise light unit, metallic framework, carbon fiber composite material core and conductor, described smooth unit is embedded in the metallic framework, carbon fiber composite material core wraps metallic framework, and conductor is stranded in the outer surface of carbon fiber composite material core.

The light unit is in the inside of carbon fiber composite material core in this scheme, to not influence of layer structure, therefore make the stretching resistance of Optical Fiber composite overhead Ground Wire and conductive capability design and calculate very simple; The carrier that adopts original galvanized steel wire of carbon fiber composite material core replacement or aluminium-clad steel wire to be used as bearing pulling force, with regard to not needing galvanized steel wire or aluminium-clad steel wire are carried out preforming like this, and the internal diameter of carbon fiber composite material core can come to determine as required, therefore the core number of the inside optical fiber can increase, and the production that so just makes heavy in section, big core count Optical Fiber composite overhead Ground Wire is very easy to.

Because carbon fiber composite material core has intensity height, in light weight and good rigidly, so the weight of Optical Fiber composite overhead Ground Wire can alleviate greatly.

Beneficial effect: compared with prior art, the utility model has the advantages that and adopt carbon fiber composite material core, can expand the specification limit of Optical Fiber composite overhead Ground Wire as the carrier of bearing pulling force; It is original 1/4 that the weight that reduces Optical Fiber composite overhead Ground Wire is reduced to approximately, and intensity is brought up to original 2 times, can reduce stringing iron tower load and laying installation cost like this, shortens installation period greatly, the raising fail safe; Can make heavy in section, big core number Optical Fiber composite overhead Ground Wire design and produce simple.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in drawings, a kind of Optical Fiber composite overhead Ground Wire of the utility model, comprise light unit 1, aluminium skeleton 2, carbon fiber composite material core 3 and aluminum or aluminum alloy line 4, light unit 1 is embedded in the aluminium skeleton 2, carbon fiber composite material core 3 wraps aluminium skeleton 2, and aluminum or aluminum alloy line 4 is stranded in the outer surface of carbon fiber composite material core 3.When the carbon fiber composite material core moulding, aluminium skeleton 2 and light unit 1 are preset at the inside; Outer aluminum or aluminum alloy line uses the equipment of traditional Optical Fiber composite overhead Ground Wire to produce traditionally or uses the wire twisting equipment of steel reinforced aluminium conductor directly stranded.

The above only is a preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
