Description
Technical field
The utility model relates to electrical equipment technical fields, and in particular to a kind of cable.
Background technique
Currently, existing common cable mainly includes cable core made of solid conductor and insulating layer, covered in cable core outsourcing
It is equipped with restrictive coating.Although the cable of this spline structure is able to carry out transmission of electricity, in electricity transmission process, solid conductor calorific value compared with
Height, and limited by structure, heat dissipation effect is poor, especially upper in high current setting in use, not can be carried out for a long time
Work continuously, otherwise lasting high temperature can make restrictive coating accelerated ageing, substantially reduce service life, increase use at
This.
Utility model content
The purpose of the utility model is to provide a kind of annular centreless cables, solve at least one above technical problem.
The technical issues of the utility model is solved can be realized using following technical scheme:
Annular centreless cable, including cable core and sheath, the cable core include that at least both threads core, the core includes conductor
And insulating layer, which is characterized in that the sheath includes inner restrictive coating and external sheath layer, and the cable core is wound around the inner restrictive coating
It is hollow cavity on the inside of the inner restrictive coating between the external sheath layer；
The inner restrictive coating is made of heat conductive insulating rubber, the inner surface of the inner restrictive coating along the sheath length
It spends direction and is equipped with several strip projected parts, form radiating ribs structure.
Heat conductive insulating rubber is the prior art.With the above arrangement, can divulge information in hollow cavity or water flowing, to cable
It radiates, so that protective sheath layer, extends the service life of cable.Heat is conducted by heat conductive insulating rubber, and radiating ribs structure increases
The contact area of big inner restrictive coating and heat eliminating medium, accelerated heat conduction, meanwhile, radiating ribs structure, which can also play, generates turbulent flow
Effect.Alternatively, so that the global density of cable is relatively small, therefore can be used as buoyant cable use since cable is hollow.
Optionally, material water-proof material is filled between the inner restrictive coating and shown external sheath layer, the material water-proof material is resistance
Pigment, waterstop, any one or a few in water blocking yarn.
When water flowing in hollow cavity or cable float in water, material water-proof material can be absorbed on the outside of sheath or inside
The water of leakage, to protect cable core.
Optionally, at least one wirerope is equipped in the hollow cavity, the length direction of the wirerope is parallel to described
The length direction of sheath.
By the way that wirerope is arranged in hollow cavity, to enhance the tensile resistance of cable
Optionally, section is equipped in the hollow cavity is in criss-cross plastic stent, and the wirerope is fixed on the modeling
In the groove for expecting bracket.
Wirerope is avoided to shake in hollow cavity.
Further, the plastic stent is alongst helically twisted, and the wirerope-winding is fixed on the plastics
In the groove of bracket.
Be fixed on wirerope can on plastic stent without additional component.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the utility model；
Fig. 2 is another sectional view of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig.1, Fig. 2, annular centreless cable, including cable core 1 and sheath, cable core 1 include at least both threads core, core packet
Include conductor and insulating layer, sheath includes inner restrictive coating 2 and external sheath layer 3, cable core 1 be wound around inner restrictive coating 2 and external sheath layer 3 it
Between, it is hollow cavity 4 on the inside of inner restrictive coating 2；Inner restrictive coating 2 is made of heat conductive insulating rubber, the inner surface of inner restrictive coating 2 along
The length direction of sheath is equipped with several strip projected parts, forms radiating ribs structure 5.Heat conductive insulating rubber is the prior art.By with
Upper setting, can divulge information or water flowing in hollow cavity 4, radiate to cable, so that protective sheath layer, extends the longevity of cable
Life.Heat is conducted by heat conductive insulating rubber, and radiating ribs structure 5 increases the contact area of inner restrictive coating 2 and heat eliminating medium, accelerates
Heat conduction, meanwhile, radiating ribs structure 5 can also play the role of generating turbulent flow.Alternatively, since cable is hollow, so that cable
Global density is relatively small, therefore can be used as buoyant cable use.
Between inner restrictive coating 2 and shown external sheath layer 3 be filled with material water-proof material 6, material water-proof material 6 be water-proofing powder, waterstop,
Any one or a few in water blocking yarn.When water flowing in hollow cavity 4 or cable float in water, material water-proof material 6 can be inhaled
The water that on the outside of sheath or inside leaks is received, to protect cable core 1.
At least one wirerope 7 is equipped in hollow cavity 4, the length direction of wirerope 7 is parallel to the length direction of sheath.It is logical
The setting wirerope 7 in hollow cavity 4 is crossed, to enhance the tensile resistance of cable
It is in criss-cross plastic stent 8 that section is equipped in hollow cavity 4, and wirerope 7 is fixed in the groove of plastic stent 8.
Wirerope 7 is avoided to shake in hollow cavity 4.
Plastic stent 8 is alongst helically twisted, and wirerope 7 is fastened in the groove of plastic stent 8.Make steel
Cord 7 can be fixed on plastic stent 8 without additional component.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model also has
Various changes and modifications, these changes and improvements are both fallen in the range of the requires of the utility model protection.The requires of the utility model
The range of protection is defined by the appending claims and its equivalent thereof.
