Abstract
The invention relates to a novel power cable, which comprises a conductor, wherein an insulating layer wraps the conductor; a filling layer is arranged outside the insulating layer of the conductor; a triangular channel is formed in the filling layer; a liner layer is arranged outside the filling layer; an armor layer is arranged outside the liner layer; and a cable sheath layer is arranged outside the armor layer. The novel power cable is simple and novel in structure, good in radiating effect, long in service life, non-toxic and environment-friendly.
Description
Technical field
The present invention relates to belong to field of cables, be specifically related to a kind of heat radiation cable.
Background technology
Power cable is meant each or a plurality of conductor outer wrap layer of annular insulating barrier, and the electric wire in conductor and the shared same axle center of insulating barrier, whole then cable is encased by the sheath of polyvinyl chloride or other materials, carries out the conduction instrument of electric energy transmitting.The interior external insulation of temperature that temperature rise that is produced when as everyone knows, the transmission capacity of cable is decided by the conductor transmission current and conductor outer insulating material can bear for a long time and cable is the ability of medium distribute heat towards periphery.Traditional cable is because the effective section that distributes is narrow, so thermal resistance value is bigger.Especially the relatively large power cable of capacity in the energising running, objectively can produce great amount of heat, and receives restrictions such as the construction of cable and material, external environment condition, and the heat of generation is difficult to distribute very soon, thereby causes the cable rapid warm raising.Cable heats up and not only can cause the decline of cable current capacity, and can cause the thermal breakdown of cable when serious; Simultaneously, the cable intensification has also been quickened cable and has been worn out, and has reduced the Acceptable life of cable.For this reason, people propose multiple measure, to reduce the work heating of cable.Therefore, people more expects adopting the water-cooled cable structure, and amalgamation has water service pipe between cable core, takes away the heat that cable core produces with circulating water, thereby reaches the cooling cable.Yet Water cooling cable is for guaranteeing insulation, and the warm water tube wall needs thicker, so not only influences the bending property of cable; And the outside diameter of cable increases considerably, and be unfavorable for equally normally laying, and manufacturing cost improves bigger; The potential safety hazard that existence in service is very big; Owing to receive the high-tension cable structural constraint, be difficult in and add the thicker water service pipe of tube wall in the cable, so the Water cooling cable structure only is applicable to low-voltage cable.
Existing flame-retardant layer generally adopts glass fiber to fill; Glass fiber is filled to cable direct labor and site operation personnel and is brought very big trouble, and the workshop workman is flown upward in the full workshop of glass fiber when doing glass fiber and fill stranding, gets on the skin not only pain but also itches and can not take out; With the occupational health that has a strong impact on the workman; And not environmental protection, glass fiber is filled the fire retardancy that has only satisfied cable, and is more harm than good.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of novelty simple in structure in order to overcome deficiency of the prior art, good heat dissipation effect, long service life, the novel electric power cable of asepsis environment-protecting.
Technical scheme: in order to solve the problems of the technologies described above, novel electric power cable of the present invention, it comprises conductor; Be provided with insulating barrier in said conductor outerwrap; Outside the insulating barrier of said conductor, be provided with packed layer, in said packed layer, be provided with triangular duct, outside said packed layer, be provided with inner covering; Outside said inner covering, be provided with armour, outside said armour, be provided with the cable cover(ing) layer.
Said conductor is three, and is copper conductor.
Said triangular duct has three, is evenly distributed in the said packed layer.
Said packed layer adopts the silicon carbide compound inserts.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention is provided with triangular duct in packed layer, play good heat-radiation effect, inserts adopts composite material of silicon carbide, asepsis environment-protecting meets the environmental protection theory.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein:
1, conductor; 2, insulating barrier; 3, packed layer; 4, triangular duct; 5, inner covering; 6, armour; 7, cable cover(ing) layer
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, a kind of novel electric power cable of the present invention belongs to field of cables, and it comprises conductor 1; Be provided with insulating barrier 2 in said conductor 1 outerwrap, outside the insulating barrier 2 of said conductor 1, be provided with packed layer 3, in said packed layer 3, be provided with triangular duct 4; Said triangular duct 4 plays good heat-radiation effect, becomes present heatsink transverse by former vertical heat radiation, and heat radiation is very fast; Thereby improved the useful life of cable; Outside said packed layer 3, be provided with inner covering 5, outside said inner covering 5, be provided with armour 6, outside said armour 6, be provided with cable cover(ing) layer 7; Said conductor 1 is three, and is copper conductor; Said triangular duct 4 has three, is evenly distributed in the said packed layer 3; Said packed layer 3 adopts the silicon carbide compound inserts.The present invention's novelty simple in structure, good heat dissipation effect adopts the silicon carbide compound inserts, and asepsis environment-protecting meets green new concept.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
