Abstract
The utility model discloses a two-core environmental-friendly shield cable for a communication power supply, comprising two semi-circular copper conductors prepared by intertwist and die compressing of 7 to 19 copper strand wires. Each copper strand wire is formed by the intertwist of several single copper wires; an environmental-friendly flame retardation polyvinyl chloride layer is coated between the two semi-circular copper conductors and on the external surfaces of the two semi-circular copper conductors; the diameter of a single copper wire in the copper strand wires is from 0.35 to 0.45 mm; a shield layer formed by braiding of several bare copper wires is coated on the external surface of the environmental-friendly flame retardation polyvinyl chloride layer; and a protective layer is coated on the external surface of the shield layer. According to the environmental-friendly shield cable provided in the utility model, the external electromagnetic interference resistant performance and the roundness are good, the thermal diffusivity is enhanced, the cost is low, and technology realization is simple.
Description
Technical field
The utility model relates to a kind of power cable transmission field, is specifically related to a kind of communication power supply with two core environmental protection shielded type cables.
Background technology
The existing communication power supply is generally circle with the most conductors of cable, when making cable, for guaranteeing the roundness of cable, the cable core domestic demand is added more filling member, causes the finished cable external diameter larger, poor radiation, cable laying takes up room greatly, and the wood that manufactures of cable also increases.Therefore, how to design that a kind of roundness is good, heat dispersion is improved, cost is low, production technology realizes simply, becomes the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model purpose provides a kind of communication power supply with two core environmental protection shielded type cables, the anti-outside electromagnetic interference performance of this environmental protection shielded type cable and roundness is good, heat dispersion is improved, cost is low, production technology realizes simple.
For achieving the above object, the technical solution adopted in the utility model is: a kind of communication power supply is with two core environmental protection shielded type cables, comprise: two by 7～19 strands of copper strand wire semicircle copper conductors stranded and that suppress to form through mould, single copper wire is stranded forms by several for described copper strand wire, all be coated with as the environmental protection flame retardant polyvinyl chloride layer that insulate with outer surface between two semicircle copper conductors, single brass wire diameter in the described copper strand wire is 0.35～0.45mm, the screen that is formed by some bare copper wire braidings is coated on described environmental protection flame retardant polyvinyl chloride layer outer surface, and a restrictive coating is coated on described screen outer surface.
It is as follows further to improve technical scheme in the technique scheme:
1, in the such scheme, a polyester belt is wrapped between described environmental protection flame retardant polyvinyl chloride layer and screen.
2, in the such scheme, a glass tape is wrapped between described polyester belt and screen.
3, in the such scheme, the copper strand wire number that described semicircle copper conductor contains is 7 strands, and the single brass wire diameter in this copper strand wire is 0.401 mm.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model communication power supply is with the anti-outside electromagnetic interference performance of two core environmental protection shielded type cables and roundness is good, heat dispersion is improved, meet environmental requirement, and preferred copper strand wire number and copper strand wire diameter have further improved the performance index of product, no longer add filler during stranding; Secondly, the environmental protection shielded type cable lay take up room little, even in the less communication power supply machine room in space, install also very convenient.
Description of drawings
Accompanying drawing 1 for the utility model communication power supply with two core environmental protection shielded type cable structural representations.
In the above accompanying drawing: 1, copper strand wire; 2, semicircle copper conductor; 3, environmental protection flame retardant polyvinyl chloride layer; 4, polyester belt; 5, glass tape; 6, bare copper wire; 7, screen; 8, restrictive coating.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of communication power supply is with two core environmental protection shielded type cables, comprise: two by 7～19 strands of copper strand wires, 1 semicircle copper conductor 2 stranded and that suppress to form through mould, single copper wire is stranded forms by several for described copper strand wire 1, all be coated with as the environmental protection flame retardant polyvinyl chloride layer 3 that insulate with outer surface between two semicircle copper conductors 2, single brass wire diameter in the described copper strand wire 1 is 0.35～0.45mm, the screen 7 that is formed by some bare copper wire 6 braidings is coated on described environmental protection flame retardant polyvinyl chloride layer 3 outer surfaces, and a restrictive coating 8 is coated on described screen 7 outer surfaces.
One polyester belt 4 is wrapped between described environmental protection flame retardant polyvinyl chloride layer 3 and screen 7.
One glass tape 5 is wrapped between described polyester belt 4 and screen 7.
Copper strand wire 1 number that above-mentioned semicircle copper conductor 2 contains is 7 strands, and the single brass wire diameter in this copper strand wire 1 is 0.401 mm.
When adopting above-mentioned communication power supply with two core environmental protection shielded type cables, anti-outside electromagnetic interference performance and roundness is good, heat dispersion is improved, meet environmental requirement need not be added filler during stranding; Secondly, this communication power supply with two core environmental protection shielded type cables lay take up room little, even installation is also very convenient in the less communication power supply machine room in space.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection range of the present utility model.
