Abstract
An outdoor communication optical cable with foamed filling rope comprising a cable core, and an outer sheath, the filling rope placed inside the cable core is a foamed filling rope comprising a core wire and an outer foamed layer. During the core wire twisting of the optical cable, other elements exhibit no deformation since the outer foamed layer of the filling rope is very soft, thus the cable core is easy to maintain a round shape. And also because the light weight of the filling rope, the weight of the present utility model is reduced and thus the transportation cost is decreased.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially with the communication outdoor optical cable of foaming packing gasket.
Background technology
Existing communication generally adopts high density polyethylene to make with the gasket for packing in its cable core of outdoor optical cable, because hardness is higher, easily makes the cable core distortion when gasket for packing and other element twist altogether in the stranded process of cable core, influences the roundness of optical cable; Because the density of material height of gasket for packing, so the weight of optical cable increases, transportation cost improves.
Summary of the invention
In order to overcome the deficiency of existing communication with outdoor optical cable, the utility model provides a kind of communication outdoor optical cable with foaming packing gasket, and its roundness is good, and weight is lighter, and transportation cost is low.
A kind of communication with foaming packing gasket that the utility model provides comprises cable core (10) and oversheath (11) thereof with outdoor optical cable, have optical fiber (4) and loose sleeve pipe (6) thereof, central reinforce member (8) in the cable core (10), the gasket for packing (1) with heart yearn (3) and outsourcing foaming layer (2) thereof is set in the cable core (10).
For increasing intensity of the present utility model, improve shielding properties, plastic-aluminum or composite steel-plastic belt (7) are set between cable core (10) and oversheath (11).
The beneficial effects of the utility model are: because the gasket for packing (1) with heart yearn (3) and outsourcing foaming layer (2) thereof is set in cable core (10), gasket for packing (1) can not make loose sleeve pipe (6) be out of shape because of its foaming layer (2) is softer with loose sleeve pipe (6) when twisting altogether in the stranded process of cable core (10), cable core (10) just can not be out of shape yet, and does not influence the roundness of optical cable; Because gasket for packing (1) weight is lighter, the utility model weight is reduced again, can reduce transportation cost.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1. gasket for packing, 2. foaming layer, 3. heart yearn, 4. optical fiber, 5. fine cream, 6. loose sleeve pipe, 7. plastic-aluminum or composite steel-plastic belt, 8. central reinforce member, the cable cream that 9. blocks water, 10. cable core, 11. oversheaths.
Embodiment
In Fig. 1, implement the making that key of the present utility model is gasket for packing (1), concrete scheme is such: the high density polyethylene base resin with 99% is a base-material, it is one that the nucleator of interpolation 1% (being made up of 5% modification azo virtue diamides and 95% low density polyethylene) mixes back fusion refining, making heart yearn (3) with the glass yarn extrudes at a high speed under 165-185 ℃ of temperature, form foaming layer (2), foam degrees is 60-70%, promptly makes the gasket for packing (1) of foaming.The making of the utility model remainder is identical with outdoor optical cable with existing communication.
Claims (2)
1, a kind of communication outdoor optical cable with foaming packing gasket comprises cable core and oversheath thereof, has optical fiber and loose sleeve pipe thereof, central reinforce member in the cable core, it is characterized in that being provided with in the cable core gasket for packing with heart yearn and outsourcing foaming layer thereof.
2, by the described a kind of communication outdoor optical cable of claim 1, it is characterized in that between cable core and oversheath, being provided with plastic-aluminum or composite steel-plastic belt with foaming packing gasket.
