The utility model discloses a structure of optoelectrical composite land cable can not only reduce cost, and the productivity effect is high, and the fade performance that still enables the optical cable is difficult to increase.
Description
Technical field
The utility model relates to a kind of photoelectricity compound land cable structure.
Background technology
The structure of optoelectronic composite cable of existing market application arranges one deck resilient coating outside cable core, and in resilient coating, two ends diametrically arrange the optical cable component wire of a detection streamer operating temperature and communication respectively, each wrapped hard copper silk side by side in both sides of optical cable component wire.Between cable core and resilient coating, enhancement layer, internal shield, insulating barrier and outer shielding layer are also set.The effect of hard copper silk is the intensity strengthening optical cable component wire, plays the effect of ground connection simultaneously, prevents short circuit.Although this photoelectric compound cable can meet the indexs such as fire prevention, waterproof, antidetonation, anti-shearing force, the cost of hard copper silk is higher, and tensile strength neither be very high, easily breaks in production process, and productivity effect is reduced.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides the structure of a kind of photoelectricity compound land cable, and it can not only reduce costs, and productivity effect is high, and the fade performance of optical cable can also be made to be not easy to increase.
The purpose of this utility model is achieved in that the structure of a kind of photoelectricity compound land cable, comprises cable core, resilient coating, two optical cable component wires; Wherein,
Described resilient coating is arranged on the periphery of cable core;
Two described optical cable component wires are arranged on the two ends of the same diameter line along described resilient coating correspondingly, and the both sides of these a two optical cable component wires difference wrapped stainless steel wire side by side;
Enhancement layer, internal shield, insulating barrier and outer shielding layer is also set gradually between described cable core and described resilient coating;
Semiconductor waterstop, bitumen layer, oversheath and graphite linings is set gradually outside described resilient coating.
The structure of above-mentioned photoelectricity compound land cable, wherein, described enhancement layer is wrapped semiconductive high strength band outside described cable core.
The structure of above-mentioned photoelectricity compound land cable, wherein, described resilient coating is wrapped semi-conductive buffer water-blocking band outside outer shielding layer.
The structure of above-mentioned photoelectricity compound land cable, wherein, described oversheath adopts the material that with the addition of termite-proof medicine to make.
The structure of above-mentioned photoelectricity compound land cable, wherein, described cable core is copper conductor.
The structure tool of photoelectricity compound land of the present utility model cable has the following advantages:

5. effectively can prevent the infringement of termite.
Accompanying drawing explanation
Fig. 1 is the sectional view of the structure of photoelectricity compound land of the present utility model cable.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
First refer to Fig. 1, the structure of a kind of photoelectricity compound land of the present utility model cable, comprise cable core 1, resilient coating 6, two communication cable heart yearns 7; Wherein:
Resilient coating 6 is arranged on the periphery of cable core 1; Cable core 1 is copper conductor;
Enhancement layer 2, internal shield 3, insulating barrier 4 and outer shielding layer 5 is also set gradually between cable core 1 and resilient coating 6; Enhancement layer 2 is wrapped semiconductive high strength band outside cable core 1; Resilient coating 6 is wrapped semi-conductive buffer water-blocking band outside outer shielding layer 5;
Two optical cable component wires 7 are arranged on the two ends of the same diameter line along resilient coating 6 correspondingly, and the both sides of a two optical cable component wires 7 difference wrapped stainless steel wire 70 side by side;
Semiconductor waterstop 8, bitumen layer 9, oversheath 10 and graphite linings 11 is set gradually outside resilient coating 6; Oversheath 10 adopts the material that with the addition of termite-proof medicine to make.
Photoelectricity compound land of the present utility model cable, optical cable component wire 7 is wherein the built-in optical cable of stainless steel tube of two cores, be arranged on the surface of resilient coating 6, GI50/125 (for on-line checkingi temperature) and SM/652d (for communication) respectively, be convenient to photoelectric compound cable in running, the temperature that on-line checkingi photoelectric compound cable runs and communication, safe and reliable when ensureing that photoelectric compound cable runs.Substitute the hard copper silk of prior art with stainless steel wire 70, and the effect of stainless steel wire 70 is the intensity strengthening cable core 1, plays the effect of ground connection simultaneously, prevents short circuit.
Photoelectricity compound land of the present utility model cable; the function playing insulative water-proof is functionally needed at endothecium structure; especially enhancement layer 2, internal shield 3, insulating barrier 4, outer shielding layer 5 and resilient coating 6; therefore these protective layers all adopt the material of insulation, waterproof in the selection of material; and structurally fit tightly, consider the infiltration of anti-sealing from material, structure two aspect simultaneously.On layer structure, the utility model mainly considers termite-proof function, in the material of oversheath 10, therefore with the addition of doses to the poisonous medicine killing effect of termite, makes cable become Drug cable, effectively can prevent the infringement of termite.
