Abstract
The utility model discloses a self-supporting smart meter data cable, which belongs to the technical field of data cables and comprises two insulating core wires and waterproof yarns positioned between the two insulating core wires. The insulating core wires and waterproof yarns are mutually stranded to form a cable core, the periphery of the cable core is wrapped by an aluminum-foil shielding layer, the periphery of the aluminum-foil shielding layer is wrapped by a copper wire braided layer, the periphery of the copper wire braided layer is extruded with a high-density outer polyethylene sheath, one side of the cable is further provided with a soft steel wire rope parallel to the cable, the periphery of the soft steel wire rope is wrapped by a steel wire rope protecting layer, and the outer wall of the steel wire rope protecting layer is adhered with the outer wall of the high-density outer polyethylene sheath. The self-supporting smart meter data cable has fine waterproof performance, the dead weight of the cable and pulling force applied to the cable are borne by the steel wire rope without penetrating tubes, the cable can be directly used for outdoor long-span laying, and laying cost is reduced greatly.
Description
Technical field
The utility model relates to a kind of data cable, and particularly a kind of self-bearing type intelligent electric meter data cable belongs to the cable technology field.
Background technology
The use of intelligent electric meter is the part that intelligent grid is built, and the transfer of data of intelligent electric meter needs very high reliability.Existing intelligent electric meter data cable comprises the insulation heart yearn that is positioned at the center, and the periphery of insulation heart yearn is coated with screen, and the periphery of screen is coated with the copper wire braid, and the periphery of copper wire braid is extruded with oversheath.This data cable tensile strength is low, and water resistance is poor, can only cable installation in pipe, meet distance electricity consumer far away, and laid down cost can significantly increase.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of self-bearing type intelligent electric meter data cable is provided, and can be directly used in outdoor laid, the tensile strength height, and water resistance is good.
For solving above technical problem, a kind of self-bearing type intelligent electric meter data cable provided by the utility model, comprise that two thoroughly do away with edge heart yearn and the water blocking yarns between two eradication edge heart yearns, the mutual stranded formation cable core of described insulation heart yearn and water blocking yarn, the periphery of described cable core is coated with foil shielding layer, the periphery of described foil shielding layer is coated with the copper wire braid, and the periphery of described copper wire braid is extruded with the high density polyethylene (HDPE) oversheath; One side of this cable also is provided with the flexible steel cable parallel with cable, and the periphery of described flexible steel cable is coated with the steel wire rope protective layer, and the outer wall of described steel wire rope protective layer is mutually bonding with the outer wall of described high density polyethylene (HDPE) oversheath.
With respect to prior art, the utility model has been obtained following beneficial effect: two thoroughly do away with water blocking yarn of interpolation between the edge heart yearn, can be in the circulation that stops moisture and moisture; The deadweight of cable and suffered pulling force are carried by steel wire rope, need not poling, can be directly used in outdoor large span and lay, and greatly reduce laid down cost.
Description of drawings
Fig. 1 is the structural representation of the utility model self-bearing type intelligent electric meter data cable.
Among the figure: 1 cored wire conductor; 2 high density polyethylene (HDPE) insulating barriers; 3 water blocking yarns; 4 foil shielding layers; 5 copper wire braids; 6 high density polyethylene (HDPE) oversheaths; 7 flexible steel cables; 8 steel wire rope protective layers.
Embodiment
As shown in Figure 1, self-bearing type intelligent electric meter data cable of the present utility model comprises that two thoroughly do away with edge heart yearn and the water blocking yarns 3 between two eradication edge heart yearns, insulation heart yearn and water blocking yarn 3 mutual stranded formation cable cores.Every eradication edge heart yearn comprises cored wire conductor 1 and is coated on cored wire conductor 1 high density polyethylene (HDPE) insulating barrier 2 outward.The periphery of cable core is coated with foil shielding layer 4, and the periphery of foil shielding layer 4 is coated with copper wire braid 5, and the periphery of copper wire braid 5 is extruded with high density polyethylene (HDPE) oversheath 6; One side of this cable also is provided with the flexible steel cable 7 parallel with cable, and the periphery of flexible steel cable is coated with steel wire rope protective layer 8, and the outer wall of steel wire rope protective layer 8 is mutually bonding with the outer wall of high density polyethylene (HDPE) oversheath 6.
It is stranded the forming of copper free wire of 0.20mm that the conductor of insulation heart yearn adopts diameter, and two thoroughly do away with water blocking yarn of interpolation between the edge heart yearn, can stop the circulation of moisture and moisture in 5cm.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
Claims (1)
1. self-bearing type intelligent electric meter data cable, it is characterized in that: comprise that two thoroughly do away with edge heart yearn and the water blocking yarns between two eradication edge heart yearns, the mutual stranded formation cable core of described insulation heart yearn and water blocking yarn, the periphery of described cable core is coated with foil shielding layer, the periphery of described foil shielding layer is coated with the copper wire braid, and the periphery of described copper wire braid is extruded with the high density polyethylene (HDPE) oversheath; One side of this cable also is provided with the flexible steel cable parallel with cable, and the periphery of described flexible steel cable is coated with the steel wire rope protective layer, and the outer wall of described steel wire rope protective layer is mutually bonding with the outer wall of described high density polyethylene (HDPE) oversheath.
