Abstract
The utility model discloses a multi-core optical fiber composite overhead ground wire (OPGW), which comprises an optical unit, and a first twisted wire layer and a second twisted wire layer which are twisted outside the optical unit, wherein the first twisted wire layer consists of seven aluminum-clad copper wires and the second twisted wire layer consists of twelve aluminum alloy wires. On the premise that the mechanical performance and the electrical performance of the OPGW are not affected, the diameter of the optical unit is increased, the number of optical fibers which can be held in the optical unit is greatly increased and the communication performance of the OPGW is improved.
Description
Technical field
The utility model relates to a kind of multicore and counts Optical Fiber composite overhead Ground Wire.
Background technology
As shown in Figure 1, traditional center type Optical Fiber composite overhead Ground Wire (OPGW) is based on 1+6+12, promptly one smooth unit 1, center ', the light unit 1 ' outer first twisted wire layer 2 ' be 6 wires, the first twisted wire layer 2 ' outer second twisted wire layer 3 ' be 12 wires.
Summary of the invention
The utility model purpose is: provide a kind of multicore to count Optical Fiber composite overhead Ground Wire, it is under the prerequisite of machinery that does not influence OPGW and electric property, the diameter of the aluminium-clad steel wire by reducing by the first twisted wire layer, increase the quantity of the aluminium-clad steel wire of the first twisted wire layer, to improve the space in the first twisted wire layer, thereby increase the diameter of light unit, improve the number of fibers that to hold greatly, improved the communication performance of OPGW.
The technical solution of the utility model is: a kind of multicore is counted Optical Fiber composite overhead Ground Wire, comprises the light unit and is stranded in the first twisted wire layer and the second twisted wire layer outside the light unit, and the described first twisted wire layer is 7 aluminium-clad steel wires, and the second twisted wire layer is 12 aluminium alloy wires.
Described smooth unit comprises stainless steel tube, is provided with multifiber in the stainless steel tube.
The diameter of the aluminium-clad steel wire of the above-mentioned first twisted wire layer is less than the diameter of the metal wire of the existing first twisted wire layer, so that the external diameter of the first twisted wire layer is consistent with the external diameter of the existing second twisted wire layer, and internal diameter is less than the internal diameter of the existing second twisted wire layer.
The utility model has the advantages that: the utility model is under the situation that does not change entire outer diameter, the diameter of the aluminium-clad steel wire by reducing by the first twisted wire layer, increase the quantity of the aluminium-clad steel wire of the first twisted wire layer, to improve the space in the first twisted wire layer, thereby increase the diameter of light unit, improve the number of fibers that to hold greatly, improved the communication performance of OPGW.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is existing structural representation;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1,1 ' light unit; 2,2 ' the first twisted wire layers; 3,3 ' the second twisted wire layers; 4 stainless steel tubes; 5 optical fiber.
Embodiment
Embodiment: as shown in Figure 2, a kind of multicore is counted Optical Fiber composite overhead Ground Wire, comprises light unit 1 and is stranded in the light unit 1 first twisted wire layer 2 and the second twisted wire layer 3 outward, and the described first twisted wire layer 2 is 7 aluminium-clad steel wires, and the second twisted wire layer 3 is 12 aluminium alloy wires.Described smooth unit 1 comprises stainless steel tube 4, is provided with multifiber 5 in the stainless steel tube 4.
The diameter of the aluminium-clad steel wire of the above-mentioned first twisted wire layer 2 less than the existing first twisted wire layer 2 ' the diameter of metal wire so that the external diameter of the first twisted wire layer 2 and the existing second twisted wire layer 2 ' external diameter consistent, and internal diameter less than have now the second twisted wire layer 2 ' internal diameter.
The utility model is under the situation that does not change entire outer diameter, the diameter of the aluminium-clad steel wire by reducing by the first twisted wire layer 2, increase the quantity of the aluminium-clad steel wire of the first twisted wire layer 2, to improve the space in the first twisted wire layer 2, thereby increase the diameter of light unit 1, improve optical fiber 5 quantity that to hold greatly, improved the communication performance of OPGW.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
