Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to Fig. 4, a kind of insulated cable, comprises body, and described body has heart yearn, coating layer and obturator.
Heart yearn is circumferentially arranged by 3 root heart yearns 1 and forms, and every root heart yearn 1 is made up of copper conductor and the insulating barrier be arranged on outside copper conductor, and described copper conductor is closed by 10 ~ 12 TC skein silks and forms.
Coating layer is arranged on outside described heart yearn, the skin 3 that described coating layer has teflon insulation layer 2 from inside to outside and is made of plastics, between insulating barrier 2 and outer 3, for enclosure space, (left end in the space between insulating barrier and skin arranges a ring-type left side and encloses, right-hand member arranges the ring-type right side and encloses, insulating barrier, skin, a left side enclose and a common formation confined space is enclosed on the right side), filling liquid heat conductive body in enclosure space.Described liquid heat conductive body is conduction oil.Liquid heat conductive body also can select other liquid materials.
Obturator 5 in a tubular form, is made up of highstrenghtpiston, and described obturator 5 is arranged on the space place between 3 root heart yearns 1.One end air blast of obturator carries out air blast, and the air in obturator flows and takes away inner heat, and discharge from the other end, improve heat dispersion, cable conductor live amount is improved.It should be noted that, between coating layer and heart yearn, except the segment space that obturator is filled, its complementary space can arrange insulation filling material.
The import 31 (through hole) of enclosure space and outlet 32 (through holes) are set on described outer 3, import 31 and outlet 32 places all removably arrange plug, and (plug is the mode of removably connecting, for import, plug is column, surface arranges screw thread, be threaded with the counterbore place of import oral area, exit is similar).By pump, liquid heat conductive body is extracted out from exit, carry out heat exchange at outside heat-exchange apparatus place (heat in liquid heat conductive body to be taken away, specifically can with reference to prior art), then cooled liquid heat conductive body refills confined space from import department.
Described obturator 5 madial wall arranges some flow-disturbing projection (not shown).Therefore the gas of obturator internal flow can be subject to the obstruction of projection, disturbance, and then flow-disturbing is formed in obturator, flow-disturbing can improve radiating efficiency, can also take away the impurity (such as trickle dust) of obturator inwall attachment simultaneously.
Described outer 3 surfaces arrange some non-slip process.Described obturator 5 sidewall arranges carbon fiber wire, and described carbon fiber wire is arranged along cable axis direction.Object strengthens the axial tensile property of obturator.
Described coating layer outer surface (i.e. superficies) axially arranges reflecting coating band 6.In cable embedded process, reflecting coating upward, is convenient to identify cable in the poor environment of light, and is facilitated personnel's Timeliness coverage cable whether to there is twisted phenomena.
The foregoing is only preferred implementation of the present utility model, protection range of the present utility model is not limited in above-mentioned execution mode, and every technical scheme belonging to the utility model principle all belongs to protection range of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection range of the present utility model.
