Shielded type cable is very important a kind of electric power cable in electric power cable out of doors, and outdoor environment wants severe a lot of compared to indoor, and traditional shielded type cable has many deficiencies on resistance to compression, heat dispersion.
Utility model content
The purpose of this utility model is to provide a kind of outdoor resistance to compression shielded type cable, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of outdoor resistance to compression shielded type cable, comprise two cable cores be extruded in fan shape in sheath, two upper and lower symmetrical intervals of cable core are arranged, and be laterally arranged with a ceramic packing in parallel, be filled with inorganic powder last layer at sheath and between cable core and ceramic packing between two cable cores; Described cable core comprises insulating barrier, internal shield, oxygen barrier layer and conductor bundle; Insulating barrier contacts with internal shield, and internal shield is positioned at the inside of insulating barrier; Internal shield contacts with oxygen barrier layer, and oxygen barrier layer is positioned at the inside of internal shield, and conductor bundle has multiple and is all arranged on the inside of oxygen barrier layer; At described sheath outer cladding steel wire woven armored layer, steel wire woven armored layer is coated with heat-conducting layer, be extruded with insulation silica gel heat-conducting layer outside heat-conducting layer, wrap up some heat-radiation belts outside insulation silica gel heat-conducting layer, the spiral back side of heat-radiation belt is provided with some ribs.
As the utility model further technical scheme, be provided with the angle of release of 9 ° ~ 15 ° between heat-radiation belt, increase area of dissipation.
As the utility model further technical scheme, heat-radiation belt is whole piece shape and is wrapped in outside insulation silica gel heat-conducting layer.
As the utility model further technical scheme, heat-radiation belt hollow is arranged, and it is built with cooling fluid.
Compared with prior art, the utility model fire resistance is good, the interior mechanical strength of cable is high, the heat diffusion that cable effectively produces by the heat-radiation belt that Exterior cable is arranged, in air, is provided with the angle of release of 9 ° ~ 15 °, increases area of dissipation between heat-radiation belt, simultaneously, the anti-extrusion ability that the heat-radiation belt that angle of release is arranged also considerably increases cable self can increase the useful life of cable, and cable shield performance and signal transmission performance good, antijamming capability is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of outdoor resistance to compression shielded type cable of the utility model.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of outdoor resistance to compression shielded type cable, comprise two cable cores be extruded in fan shape in sheath 6, two upper and lower symmetrical intervals of cable core are arranged, between two cable cores, be laterally arranged with a ceramic packing 8 in parallel, be filled with inorganic powder last layer 7 at sheath 6 and between cable core and ceramic packing 8; Described cable core comprises insulating barrier 9, internal shield 10, oxygen barrier layer 11 and conductor bundle 12; Insulating barrier 9 contacts with internal shield 10, and internal shield 10 is positioned at the inside of insulating barrier 9, and the effect of insulating barrier 9 plays insulating effect between multiple conductor bundle 12, and internal shield 10 plays the effect of shielding external interference signal; Internal shield 10 contacts with oxygen barrier layer 11, and oxygen barrier layer 11 is positioned at the inside of internal shield 10, conductor bundle 12 has multiple, all be arranged on the inside of oxygen barrier layer 11, oxygen barrier layer 11 can isolate oxygen, contribute to the signal fast transport of cable, cable adopts symmetrical structure can improve the mechanical strength of cable;
At described sheath 6 outer cladding steel wire woven armored layer 5, steel wire woven armored layer 5 is coated with heat-conducting layer 4, insulation silica gel heat-conducting layer 1 is extruded with outside heat-conducting layer 4, some heat-radiation belts 3 are wrapped up outside insulation silica gel heat-conducting layer 1, the spiral back side of heat-radiation belt 3 is provided with some ribs 2, rib 2 is equivalent to fin, the heat diffusion effectively produced by cable is in air, the angle of release of 9 ° ~ 15 ° is provided with between heat-radiation belt 3, increase area of dissipation, meanwhile, the heat-radiation belt that angle of release is arranged also considerably increases the anti-extrusion ability of cable self.
Heat-radiation belt 3 can also be that whole piece is wrapped in outside insulation silica gel heat-conducting layer 1, in order to reduce operation, and can by heat-radiation belt 3 integrally.
In another kind of embodiment of the present utility model, heat-radiation belt 3 is hollow, and cooling fluid is equipped with in the inside, and heat-conducting layer 4 transfers heat to insulation silica gel heat-conducting layer 1, cooling fluid in heat-radiation belt 3 can absorb heat rapidly, discharge heat by rib 2 again, meanwhile, cooling fluid can also play fire-retardant effect.
