Abstract
The utility model discloses a two-core flame retardation armored flexible cable, comprising two semi-circular copper conductors prepared by intertwist and die compressing of several copper strand wires. Each copper strand wire is formed by the intertwist of several single copper wires; a polyvinyl chloride layer is coated between the two semi-circular copper conductors and on the external surfaces of the two semi-circular copper conductors; a polyester belt is wrapped on the external surface of the polyvinyl chloride layer; an internal protective layer is wrapped on the external surface of the polyester belt; an armored layer formed by wrapping two layers of galvanized steel strips is coated on the external surface of the inner protective layer; an external protective layer is coated on the external surface of the armored layer; the intertwist pitch of the two semi-circular copper conductors is from 350 to 450 mm; and the thickness of the galvanized steel strips in the armored layer is 0.2 mm, and the clearance rate of the armored layer is at least 49%. According to the two-core flame retardation armored flexible cable provided in the utility model, the roundness is 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 two core flame-proof armoring flexible cables.
Background technology
The performances such as the communication power supply flexible cable is a kind of power devices connecting line for communication machine rooms such as movement, telecommunications, Netcoms, and product requirement is soft, fire-retardant.To the attention of environmental protection, all trades and professions all require product to have the performance of environmental protection along with in the world.Two conventional core flexible cables extrude with round conductor mainly that polyvinyl chloride is stranded to be formed, and for guaranteeing the roundness of cable, the cable core domestic demand is added more filling member, cause the finished cable external diameter larger, poor radiation, cable laying take up room greatly, and the manufacturing cost of cable also increases.
Summary of the invention
The utility model purpose provides a kind of two core flame-proof armoring flexible cables, and this two cores flame-proof armoring flexible cable roundness is good, heat dispersion is improved, cost is low, technique realizes simple.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two core flame-proof armoring flexible cables, comprise: two by several copper strand wires semicircle copper conductor stranded and that form through mould compacting, single copper wire is stranded forms by several for described copper strand wire, all be coated with as the polyvinyl chloride layer that insulate with outer surface between two semicircle copper conductors, one polyester belt is wrapped in described polyvinyl chloride layer outer surface, one inner restrictive coating extrudes in described polyester belt outer surface, be coated on described inner restrictive coating outer surface by the wrapped armour that forms of two-layer galvanized steel strip, an external sheath layer is coated on described armour outer surface; Described two semicircle copper conductor twisting pitch are 350 ~ 450mm.
Further improve technical scheme in the technique scheme as follows:
1, in the such scheme, the thickness of galvanized steel strip is 0.2mm in the described armour, and this armour clearance rate is at least 49%.
2, in the such scheme, described external sheath layer thickness is 1.1mm, and its eccentricity is no more than 20%.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model two core flame-proof armoring flexible cables, its roundness is good, heat dispersion is improved, meet environmental requirement, need not add filler during stranding, and preferred semicircle copper conductor twisting pitch, the thickness of galvanized steel strip and clearance rate are conducive to further improve the mechanical performance of product in the armour; Secondly, this two cores flame-proof armoring flexible 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 is the utility model two core flame-proof armoring soft cable structure schematic diagrames.
In the above accompanying drawing: 1, copper strand wire; 2, semicircle copper conductor; 3, polyvinyl chloride layer; 4, polyester belt; 5, inner restrictive coating; 6, galvanized steel strip; 7, armour; 8, external sheath layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of two core flame-proof armoring flexible cables, comprise: two by several copper strand wire 1 semicircle copper conductors 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 polyvinyl chloride layer 3 that insulate with outer surface between two semicircle copper conductors 2, one polyester belt 4 is wrapped in described polyvinyl chloride layer 3 outer surfaces, one inner restrictive coating 5 extrudes in described polyester belt 4 outer surfaces, be coated on described inner restrictive coating 5 outer surfaces by the two-layer galvanized steel strip 6 wrapped armours that form 7, an external sheath layer 8 is coated on described armour 7 outer surfaces; Described two semicircle copper conductor 2 twisting pitch are 350 ~ 450mm.
The thickness of galvanized steel strip 6 is 0.2mm in the above-mentioned armour 7, and these armour 7 clearance rates are at least 49%.
Above-mentioned external sheath layer 8 thickness are 1.1mm, and its eccentricity is no more than 20%.
When adopting above-mentioned two core flame-proof armoring flexible cable, its roundness is good, heat dispersion is improved, meet environmental requirement, need not add filler during stranding, and preferred semicircle copper conductor twisting pitch, the thickness of galvanized steel strip and clearance rate are conducive to further improve the mechanical performance of product in the armour; Secondly, this two cores flame-proof armoring flexible cable lay take up room little, even in the less communication power supply machine room in space, install also very convenient.
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.
