Abstract
An optical fiber composite overhead ground wire with a large-diameter stainless steel sleeve comprises an optical fiber unit formed by arranging the stainless steel sleeve outside an optical fiber and an aluminum-clad steel wire layer twisted outside the stainless steel sleeve, wherein the stainless steel sleeve is the large-diameter stainless steel sleeve with the diameter of 3.8-4.8 mm, and an aluminum alloy wire layer is arranged between the large-diameter stainless steel sleeve and the aluminum-clad steel wire layer. Because the utility model discloses a major diameter stainless steel sleeve can set up the optical fiber core number more than general stainless steel sleeve in order to satisfy the communication needs to can replace the compound overhead earth wire of layer-stranding's multitube structure's optic fibre, can reduction in production cost, weight reduction is convenient for erect. In addition, the number of the optical fiber cores contained in the large-diameter stainless steel sleeve is increased, so that the excess length of the optical fiber is formed, and the optical fiber is not easy to damage in the using process.
Description
Technical field
The utility model relates to a kind of overhead ground wire of transmission line, especially the Optical Fiber composite overhead Ground Wire of central tubular.
Background technology
When the Optical Fiber composite overhead Ground Wire of existing transmission line increases fiber number at needs, adopt the multitube structure of layer-twisted type usually.This is that the fiber number that is provided with in the pipe is limited because the casing diameter in the Optical Fiber composite overhead Ground Wire of existing central tubular is little.But the layer-twisted type Optical Fiber composite overhead Ground Wire production cost height of multitube structure, weight is big, sets up inconvenience.
Summary of the invention
In order to overcome the deficiency of the Optical Fiber composite overhead Ground Wire that has transmission line now, the utility model provides a kind of Optical Fiber composite overhead Ground Wire with major diameter stainless steel sleeve pipe.
A kind of Optical Fiber composite overhead Ground Wire that the utility model provides with major diameter stainless steel sleeve pipe, be included in optical fiber fiber unit and the outer stranded aluminium-clad steel wire layer of stainless steel sleeve pipe that the stainless steel sleeve pipe constitutes is set outward, the stainless steel sleeve pipe is the major diameter stainless steel sleeve pipe of diameter 3.8mm-4.8mm, is provided with the aluminium alloy wire layer between major diameter stainless steel sleeve pipe and aluminium-clad steel wire layer.
The beneficial effects of the utility model are: because major diameter stainless steel sleeve pipe of the present utility model can be provided with fiber number than general stainless steel sleeve pipe to satisfy the communication needs more, thereby can substitute the Optical Fiber composite overhead Ground Wire of the multitube structure of layer-twisted type, can reduce production costs, weight reduction is convenient to set up.In addition, the increase of major diameter stainless steel sleeve pipe content nano fiber core number helps the formation of excess fiber length, and it is impaired that optical fiber in use is difficult for.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, aluminium-clad steel wire, 2, aluminium alloy wire, 3, major diameter stainless steel sleeve pipe, 4, optical fiber, 5, fiber unit.
Embodiment
With reference to Fig. 1, optical fiber 4 is located in the major diameter stainless steel sleeve pipe 3 of diameter 3.8mm-4.8mm and makes fiber unit 5, stranded successively aluminium alloy wire 2 and aluminium-clad steel wire 1 are made aluminium alloy wire layer and aluminium-clad steel wire layer respectively outside fiber unit 5, promptly make the utility model.
