Abstract
The invention discloses one kind block water heat absorption electric wire, including the aluminium alloy conductor positioned at center and the corrugated aluminum pipe that blocks water being extruded in outside aluminium alloy conductor, in the overlapping wrapped non-woven fabrics outside corrugated aluminum pipe that blocks water, polyethylene outer sheath is extruded outside non-woven fabrics, the multiple tongues of extrusion molding on outer protective polyethylene set, the filling heat absorption cotton in tongue.The electric wire is while high intensity is kept, human body is not injured, easy to process, block-water performance is stable, good heat dissipation effect, can directly it use, the occasion that can have stringent limitation in laying narrow space, the structure size to cable and have fire resistance uses.
Description
Technical field
The invention belongs to field of cables, particularly one kind blocks water heat absorption electric wire.
Background technology
There are abundant wind energy resources and wide flat region in China sea, and close apart from power load center, makes
Obtaining coastal waters wind generating technology becomes the hot spot studied and applied recently.Since seabed natural environment is severe and its unpredictable
Property, offshore wind farm are the larger cable kinds of designing technique, manufacturing technology difficulty with submarine cable.Shallow water cable does not require nothing more than anti-
Property, also more demanding electrical insulation properties and the very high safety such as water, corrosion-resistant, resistance to mechanical drawing and external force collision
Reliability, particularly long length extra large cable are even more to propose great challenge to the manufacturing capacity and technical merit of current cable industry.
Shallow sea is widely used between continent and island, island and island and passes through the power transmission of rivers lakebed with cable.With
Automation and the fast development of China's marine cause, in following many decades, either Oversea wind power generation, or other coastal waters
Operating system, will all show shallow water cable huge demand.Since the particular surroundings of bottom of shallow sea application is, it is necessary to which cable has
Have different conductive sections, different mechanical strengths, anti-seawater leakage with corrosion etc. architectural characteristic, and using adapt to intertidal zone,
The different construction method such as subtidal zone, to meet the specific demand of Wind Power Generation Industry.Also some fire-resisting cables are not all right due to radiating, and lead
Cause naturally, bringing harm, therefore the reliability of fire-resistant wires is most important.
The content of the invention
The present invention is overcomes shortcoming existing in the prior art, there is provided one kind blocks water heat absorption electric wire, which is keeping high
While intensity, human body is not injured, easy to process, fire resistance is stablized.
One kind of the present invention blocks water heat absorption electric wire, including aluminium alloy conductor positioned at center and is extruded in aluminium alloy and leads
The external corrugated aluminum pipe that blocks water, in the overlapping wrapped non-woven fabrics outside corrugated aluminum pipe that blocks water, extrudes polyethylene outer sheath outside non-woven fabrics,
The multiple tongues of extrusion molding on outer protective polyethylene set, the filling heat absorption cotton in tongue.
Further as above-mentioned technical proposal is improved, and the outer protective polyethylene that is set in qually spaced in of the tongue is put on.
As an alternative to the above-described technical solution, the nonwoven thickness is no more than 2cm.
Beneficial effects of the present invention are：
The configuration of the present invention is simple, by using the corrugated aluminum pipe that blocks water, not only simplifies technique and improves efficiency, and make product into
Originally decline to a great extent；Present invention employs multilayer material water-proof material so that cable has very strong water stop function, will not be soaked because of moisture
Enter to cause oxidation, the corrosion of conductor, so as to influence the electrical property of cable, or even be abnormal line-outage contingency；In addition, in polyethylene
The multiple tongues of extrusion molding on oversheath, filling heat absorption cotton, the heat in cable is absorbed and distributed outward so that cable in tongue
The hidden danger that will not be produced from but bring.
Brief description of the drawings
The structure diagram of Fig. 1 present invention.
Embodiment
Elaborate below in conjunction with the accompanying drawings to embodiments of the present invention.
The heat absorption electric wire as shown in Figure 1, one kind blocks water, including aluminium alloy conductor 1 positioned at center and be extruded in aluminium alloy and lead
The external corrugated aluminum pipe 2 that blocks water, in the overlapping wrapped non-woven fabrics 3 outside corrugated aluminum pipe that blocks water, extrudes outer protective polyethylene outside non-woven fabrics
Set 4, the multiple tongues 5 of extrusion molding on outer protective polyethylene set, filling heat absorption cotton 6, the heat in cable is absorbed outward in tongue
And distribute so that cable will not be because of the excessive generation spontaneous combustion of temperature.
The outer protective polyethylene that is set in qually spaced in of the tongue is put on, so that cable keeps balance；
The nonwoven thickness is no more than 2cm, and the corrugated aluminum pipe that not so blocks water will not have shielding action.
Concrete application approach of the present invention is very much, and the above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
