Background technology
In recent years, the electric utility in China continues to develop, and the demand of cable is very big, simultaneously for wanting for power cable
Ask also higher and higher.Power cable is the cable for being used for transmission and distributing electric energy, is usually used in Urban Underground power grid, power station is drawn
Go out the submarine transmission line of circuit, the in-line power of industrial and mining enterprises and crossing river and sea.But power cable is during use
Also certain heat is will produce, generated heat can cause power cable itself prodigious wound in the long-term use
Evil；The transmittability of power cable can equally declined, power consumption becomes larger.Therefore, these problems demands existing in the prior art
It solves.
Invention content
And, the present invention provides a kind of high heat dispersion electric power in view of the above-mentioned defects in the prior art
Cable, with heat abstraction structure, the heat that can in time generate cable itself is discharged, and reduces temperature, improves security performance.
The technical solution adopted by the present invention to solve the technical problems is：High heat dispersion power cable, including more phases
The power cable core mutually to insulate, which is characterized in that insulating layer is coated with outside the every power cable core, on the insulating layer
Equipped with heat extraction hole, it is also wrapped on shielded layer outside the insulating layer, heat extraction inner tube, institute are equipped between the more power cable cores
It states heat extraction outer wall of inner tube and is equipped with multiple arcs support element, the every power cable core passes through curved support part and heat extraction inner tube
It is connected and fixed, the heat extraction inner tube wall is broached-tooth design, is additionally provided with thermal insulation layer between the more power cable cores, institute
The integral coating of thermal insulation layer, heat extraction inner tube and more power cable cores composition is stated in fire-retardant band, the fire-retardant band
Outside is coated with armor, and waterproof ventilated membrane is coated with outside the armor, heat extraction is coated with outside the waterproof ventilated membrane
Outer layer, the heat extraction outer layer are internally provided with more heat extraction outer tubes.
Further, the more heat extraction outer tubes are arranged in the same direction with power cable core, two adjacent heat extraction outer tubes
Between be interconnected.
Further, curved support part section is semicircle, is open towards fire-retardant band.
Further, the multiple curved support part is uniformly distributed along heat extraction outer wall of inner tube cross-sectional periphery direction.
The beneficial effects of the invention are as follows：Compare the prior art, high heat dispersion power cable of the invention, be equipped with it is external and
Internal dual heat extraction, is equipped with insulating layer outside every power cable core, and insulating layer is equipped with heat extraction hole, the outermost row of cable
It is equipped with heat exhausting pipe in hot outer layer, heat extraction inner tube is equipped between power cable core, running generates big calorimetric for a long time in power cable
After amount, on the one hand, heat is lost in from interior heat exhausting pipe, and on the other hand, heat is exported by heat extraction hole, into the row of heat extraction outer layer
In hot outer tube, and then it is dispersed into Exterior cable；The setting of waterproof ventilated membrane, can be on the basis of keeping water proofing property, it is ensured that electricity
Gas permeability inside cable improves radiating efficiency, and heat extraction internal tube is broached-tooth design, and increasing heat radiation area improves radiating efficiency,
Power cable core is fixed by curved support part and heat extraction inner tube, is prevented from entwining in inside, be shaken, influences service life.
