Abstract
The utility model discloses a layer-stranding cable easy to distinguish. The layer-stranding cable comprises a steel wire, a plurality of optical fibers, a cable ointment and aramid yarns, wherein the steel wire is positioned at a central position, and is wrapped by a polyethylene coating; the plurality of optical fibers are arranged around the polyethylene coating, and are wrapped by loose tubes; the cable ointment is filled into the periphery of each loose tube; the aramid yarns are used for coating the loose tubes inside; an inner polyethylene armor coat, a water-blocking tape, an aluminum tape and an outer polyethylene jacket are arranged on the outer side of the aramid yarns in sequence; the outer surface of the outer polyethylene jacket is provided with a marking line for marking the attribution of the cable; and the marking line is used for marking cables of different attributions through line shapes instead of variation of colors, so that the appearance of the marking line does not change along with the increase of the using time. When a plurality of cables are paved simultaneously, each cable is still easy to distinguish after long-term use, so that great convenience is brought to installation, maintenance and detection.
Description
Technical field
The utility model relates to a kind of product that is used for the optical communication transmission field, relates in particular to a kind of layer-stranding cable.
Background technology
In the prior art,, when many cables, optical cable pipe, same groove, laying in one ditch together, just have the deficiency that is difficult for identification, cause installation, maintenance, detect all inconveniences because mostly the profile of optical cable and cable is same color; The solution of tional identification mode is to adopt the vitta recognition technology; But along with the optical cable increase of tenure of use, bigger variation can appear in the vitta color, and produces than big-difference with original color; After causing many optical cables to lay simultaneously, the technological deficiency that is difficult to differentiate usually appears.
Summary of the invention
For overcoming the defective of above-mentioned prior art, the utility model technical matters to be solved is intended to provide a kind of layer-stranding cable that is easy to identification, so that the optical cable after long-term the use still can be differentiated easily.
For solving the problems of the technologies described above, the utility model proposes a kind of layer-stranding cable that is easy to identification, comprises the steel wire that is positioned at the centre and is wrapped up by the tygon coating; Around the setting of said tygon coating and by the multifiber of loose sleeve pipe parcel, be filled in cable ointment around each loose sleeve pipe; Said loose sleeve pipe is coated on interior aramid yarn; The parts that are positioned at the said aramid yarn outside are followed successively by polythene inner, waterstop, aluminium strip and tygon oversheath, and the outside surface of said tygon oversheath is provided with the sign line that is used to indicate the optical cable ownership.
Further, said sign line is through the ownership of lines shape variation indication optical cable.
Particularly, be filled with the fine ointment of protection optical fiber between each optical fiber, said optical fiber and fine ointment are by said loose sleeve pipe parcel; According to the structure needs, possibly also be provided with gasket for packing between the said loose sleeve pipe; Protect in being provided with in the said aramid yarn and tear rope; Protect outside between said polythene inner, waterstop, being provided with and tear rope.
After adopting said structure,, and should indicate line with its shape because the oversheath of optical cable is provided with the sign line of special indication optical cable ownership; But not color indicates the optical cable of different ownership; Like this, the outward appearance that indicates line can not change along with the increase of tenure of use, when many cables lay simultaneously; Each optical cable of use back still is easy to differentiate, distinguish for a long time, installation, maintenance, very convenient when detecting.
To and combine accompanying drawing that the utility model is elaborated through embodiment below.
Description of drawings
Fig. 1 is the described cross-sectional structure synoptic diagram that is easy to the layer-stranding cable of identification of the utility model.
Among the figure, protect in 1 steel wire, 2 tygon coatings, 3 optical fiber, 4 fine ointment, 5 loose sleeve pipes, the 6 cable ointment, 7 to tear to protect outside rope, 8 gasket for packings, 9 aramid yarns, 10 polythene inner, 11 and tear rope, 12 waterstops, 13 aluminium strips, 14 tygon oversheaths, 15 sign lines.
Embodiment
With reference to Fig. 1, the described layer-stranding cable that is easy to identification of the utility model comprises: the steel wire 1 that is positioned at the centre and is wrapped up by tygon coating 2; This steel wire is as central reinforce member, and tygon coating 2 is used to prevent the steel wire corrosion; Be provided with and by the multifiber 3 of loose sleeve pipe 5 parcels around said tygon coating 2; Be filled in around each loose sleeve pipe, be used for the cable ointment 6 that optical cable vertically blocks water; Said loose sleeve pipe is coated on interior aramid yarn 9, and the parts that are positioned at said aramid yarn 9 outsides are followed successively by polythene inner 10, waterstop 12, aluminium strip 13 and tygon oversheath 14.
Be filled with the fine ointment 4 that stops moisture to contact with optical fiber between each optical fiber, loose sleeve pipe 3 wraps up aforementioned optical fiber and fine ointment.
In order to guarantee the roundness of cable core, sometimes need be between each loose sleeve pipe, row is provided with gasket for packing 8 again.
The effect of aforementioned aramid yarn 9 is the pulling strengrths that are used to strengthen optical cable, and 10 of polythene inner are to be used to protect cable core, and waterstop 12 is used for vertically blocking water of optical cable, and aluminium strip 13 is used for the protection against the tide of optical cable.
In said aramid yarn 9 inboards, or in the cable ointment 6, also be provided be used to out stripping tygon inner sheath in protect and tear rope 7; Between said polythene inner 10, waterstop 12, be provided with outer the protecting that is used to out stripping tygon oversheath and tear rope 11.
The utility model is described to be easy to the layer-stranding cable of identification and the key distinction of prior art just is: the outside surface of above-mentioned tygon oversheath 14 is provided with the sign line 15 that is used to indicate the optical cable ownership; This sign line can form through extruding in the manufacturing process of oversheath; For different optical cables; This shape that indicates line can be different fully, even can make according to user's specific requirement.
Adopt the utility model, through indicating the setting of line, and the difformity that respectively indicates line is carried out special marking to optical cable; Change traditional optical cable indicates different ownership through the variation that indicates line color optical cable; Like this, the outward appearance that indicates line can or not be difficult for changing along with the increase of tenure of use, when many cables lay simultaneously; Each optical cable after the use still is easy to resolution, difference for a long time, and is very convenient when therefore installation, maintenance, detection.
