Abstract
The invention relates to a lightning-protection optical power cable. The lightning-protection optical power cable comprises a cable core, a filling layer arranged outside the cable core, a protecting layer covering the filling layer and a sheath layer covering the protecting layer. The cable core comprises conductors and insulating layers covering the conductors. A grounded layer is arranged between the cable core and the filling layer and is formed by twisting a plurality of copper and magnesium alloy wires. The lightning-protection optical power cable is reasonable in design structure, and can achieve the lightning protection purpose.
Description
Technical field
The present invention relates to the field of lightning protection, especially a kind of lightning-proof optical cable.
Background technology
Optical cable (Optical power cable, OPC) is that plain conductor and optical fiber are organically combined, simultaneously, go the same way, with moving towards the integrated transmission medium of electric energy transmitting and optical information.It has realized the integral fusion of flow of power, Business Stream, information flow.By once setting up, once construction, once drop into, in transferring high voltage electric energy, the information such as transferring voice, data, video, has shortened the duration greatly, has reduced construction cost, has saved resource, for solid foundation has been established in intelligent grid construction.The optical cable using at present, does not possess the object of lightning protection, in the time that thunderstorm season uses, easily causes optical cable damage phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the problem of above-mentioned middle existence, provide a kind of lightning-proof optical cable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lightning-proof optical cable; comprise core body, be located at the packed layer of core external body and be coated on the protective layer of packed layer outside and be coated on the restrictive coating of protective layer outside; described core body comprises conductor and is coated on the insulating barrier outside conductor; between described core body and packed layer, be provided with ground plane, described ground plane is that multiply copper magnesium alloy wire harness strand forms.
Described conductor is almag heart yearn.
The material of described oversheath is TPO material.
The invention has the beneficial effects as follows: described a kind of lightning-proof optical cable, its project organization rationally and can possess the object of lightning protection.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of lightning-proof optical cable of the present invention.
Accompanying drawing acceptance of the bid note is described below: 11, conductor, 12, insulating barrier, 2, packed layer, 3, protective layer, 4, restrictive coating, 5, ground plane.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of lightning-proof optical cable as shown in Figure 1; comprise core body, be located at the packed layer 2 of core external body and be coated on the protective layer 3 of packed layer 2 outsides and be coated on the restrictive coating 4 of protective layer 3 outsides; the material of oversheath 4 is TPO material; core body comprises conductor 11 and is coated on the insulating barrier 12 outside conductor; conductor 11 is almag heart yearn; between core body and packed layer 2, be provided with ground plane 5, ground plane 5 forms for multiply copper magnesium alloy wire harness twists.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
