Abstract
The utility model discloses a high-power transmission power cable. The high-power transmission power cable sequentially comprises a combined water passing pipe layer, a fine copper wire harness layer, an isolating layer and a rubber layer from inside to outside, wherein the fine copper wire harness layer is arranged outside the combined water passing pipe layer, the isolating layer is arranged outside the fine copper wire harness layer in a winding and coating mode, and the rubber layer is arranged as the outermost layer of the high-power transmission power cable in an extruding and coating mode. A control pair is further arranged inside the fine copper wire harness layer, and the control pair is tightly attached to the combined water passing pipe layer. The combined water passing pipe layer is composed of a cooling water pipe and a cold pipe closing layer which is arranged outside the cooling water pipe in a coating mode. The high-power transmission power cable is in the state of external natural cooling and center forced cooling in the working process. The control pair is tightly attached to the cooling water pipe. Therefore, the maintenance of the insulating strength is facilitated; the thermal ageing is slowed down; and the stress is small when the cable is bent.
Description
Technical field
The utility model relates to electric wire field, specifically refers to a kind of high power transmission power cable.
Background technology
Power cable is transmission high power CW service conditions, and use voltage is low, electric current is large, in use, due to conductor resistance heating, after cable heats up, produces a large amount of idle energy consumptions, and the aging and conductor that simultaneously accelerates cable is oxidized.
Aging speed adds fast again by 8-10 ℃ of temperature rising, for example, using electric conductor temperature is 65 ℃, 8 years useful life, as rise to 75 ℃, be 4 years useful life, because large electric current adds that heat radiation is bad, cable may be raised to 90 ℃ of left and right, and not only the life-span only had about 1 year, and cable loss is very large, therefore the cooling of cable is to have larger energy-conservation value.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high power transmission power cable, can dwindle operation cable dimension, increases cable flexible, can avoid again the couple corrosion of water to copper wire.
A kind of high power transmission power cable described in the utility model, comprises combination water service pipe layer from inside to outside successively, the outer thin copper wire wire harness layer of combination water service pipe layer, and the outer wrapped separator of thin copper wire wire harness layer, outermost layer extrudes rubber layer; In thin copper wire wire harness layer, be also provided with pair of control line pair, described control pair is close to combination water service pipe layer; Described combination water service pipe layer consists of cooling water pipe and the cold duct occlusion layer that is coated on outside cooling water pipe.
Further improve, described cooling water pipe adopts metal elastic reed pipe.
Further improve, described cooling confining bed is resistance to wear semiconductive crosslinked polyethylene.
Further improve, that described control pair insulation adopts is crosslinked polyetylene insulated, silicon rubber insulation or fluoroplastic insulation material.
Further improve, described rubber layer adopts haloflex and the chlorosulfonated polyethylene of flame retardant type, 90 ℃ of heatproofs, oil resistant formulated again.
The beneficial effects of the utility model are:
Intracardiac cold mode during the utility model adopts, can dwindle operation cable dimension, increases cable flexible, can avoid again the couple corrosion of water to copper wire.In cable, increase a pair of cable control pair, in the welding of gap, while stopping welding, power supply is tripping immediately, reaches and saves unloaded reactive loss, the iron loss of transformer.In this cable work, in outside natural heat dissipation and center, force the state of cooling, the tight note cooling water pipe of control pair, is conducive to keep dielectric strength, stressed little while slowing down heat ageing and cable bend.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high power transmission power cable described in the utility model, comprises combination water service pipe layer from inside to outside successively, the outer thin copper wire wire harness layer 4 of combination water service pipe layer, and the outer wrapped separator 5 of thin copper wire wire harness layer 4, outermost layer extrudes rubber layer 6; In thin copper wire wire harness layer 4, be also provided with pair of control line to 3, described control pair 3 is close to combination water service pipe layer; Described combination water service pipe layer consists of cooling water pipe 1 and the cold duct occlusion layer 2 that is coated on outside cooling water pipe 1.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
