Abstract
An optical fiber composite overhead ground wire with an optical fiber unit covered by a carbon fiber composite material layer comprises the stainless steel jacket tube optical fiber unit and aluminum-clad steel wires twisted outside the optical fiber unit. A stainless steel jacket tube is covered by the carbon fiber composite material layer. According to the utility model, the strength and the resistance to side compression of the stainless steel jacket tube can be improved, the stainless steel jacket tube is unlikely to be damaged, so optical fibers can be effectively protected from being damaged, and the operation stability and the service life of the optical fiber composite overhead ground wire can be improved. Under the condition of same strength and resistance to side compression, compared with the current optical fiber composite overhead ground wire, the optical fiber composite overhead ground wire of the utility model can decrease the external diameter of the externally twisted aluminum-clad steel wires, so that the weight of the optical fiber composite overhead ground wire is reduced, the load of stringing iron towers is decreased, and the stringing cost is saved.
Description
Technical field
The utility model relates to the overhead ground wire of a kind of high-altitude transmission line, especially OPGW.
Background technology
The existing OPGW that is used for transmission line generally is made up of the aluminium-clad steel wire of fiber unit and outsourcing thereof, and fiber unit is formed (also claiming stainless steel sleeve pipe fiber unit) by the stainless steel sleeve pipe of optical fiber and outsourcing thereof.Because not high, the lateral pressure resistant poor-performing of intensity of stainless steel sleeve pipe.In use; Variation because of amblent air temperature; Situation such as freezing appears in the surface that especially runs into OPGW, pulling force that ground wire receives and pressure strengthen, and make stainless steel sleeve pipe wherein impaired easily; And then cause damage to optical fiber, influence OPGW operation stability and useful life.
Summary of the invention
In order to overcome the deficiency of existing fiber composite overhead ground wire, the utility model provides a kind of OPGW that outside fiber unit, coats the carbon fibre composite layer.
A kind of OPGW that outside fiber unit, coats the carbon fibre composite layer that the utility model provides comprises the outer stranded aluminium-clad steel wire of stainless steel sleeve pipe fiber unit and fiber unit, covers the carbon fibre composite layer in the outsourcing of stainless steel sleeve pipe.
The beneficial effect of the utility model is: because carbon fibre composite is that a kind of intensity is high, in light weight, corrosion-resistant material; Covering the carbon fibre composite layer in the outsourcing of stainless steel sleeve pipe can strengthen intensity and the lateral pressure resistant performance of stainless steel sleeve pipe and increase weight less; Even run into the surface of ground wire occur the to freeze pulling force that causes receiving and the situation of pressure increase; Stainless steel sleeve pipe wherein also is not easy impaired; And then can effectively protect optical fiber not to be damaged, improve OPGW operation stability and useful life.Under the intensity situation identical with the lateral pressure resistant performance index; The utility model is compared with the existing fiber composite overhead ground wire, can reduce the external diameter of the stranded aluminium-clad steel wire of skin, thereby alleviates the weight of OPGW; Reduce the load of stringing iron tower, practice thrift the stringing cost.
Description of drawings
Fig. 1 is the cross sectional representation of the utility model.
In Fig. 1,1, aluminium-clad steel wire, 2, the carbon fibre composite layer, 3, optical fiber, 4, the stainless steel sleeve pipe.
Embodiment
With reference to Fig. 1, outside the interior stainless steel sleeve pipe 4 of establishing optical fiber 3, coat carbon fibre composite layer 2, stranded aluminium-clad steel wire 1 outside carbon fibre composite layer 2 is promptly processed the utility model again.
