Six layers of external coating is by interior and take the second propylene restrictive coating of shielding layer, nickel strap shielding layer, non -magnetic metal armor and tin -plated copper strip armor for polyester fiber layer, zinc -plated nickel strap armor, zinc -aluminum alloy plating in proper order outward, and the conductor sinle silk be the aluminum alloy conductor sinle silk, sets up four groups, even crowded the package in polyester fiber in situ portion, the crowded bao jiugen of conductor and four zinc -plated nickel silk drainage lines in the aluminum alloy conductor sinle silk. This kind of cable is waterproof high temperature resistant, and the fire resistance is strong, and the pull resistance is strong, and is light moreover, the softness.

Description

A kind of flame-retardant pull tension flexible cable

Technical field

This utility model belongs to field of cables, particularly relates to a kind of flame-retardant pull tension flexible cable.

Background technology

Cable is a kind of conductive media, is widely used in petrochemical industry, the every field such as computer, national defence.Cable is typically the cable of the similar rope stranded by several or several groups of wires [often organizing at least two]; often mutually insulated between group wire; and be often twisted into round four centers; whole outside is surrounded by the cover layer of high-insulation; but inner conductor and the external protection structure of cable are varied, according to different field need especially can be different.

Utility model content

In order to increase the practicality of prior art, the purpose of this utility model is to provide a kind of light, soft, high temperature resistant, flame-retardant pull tension flexible cable.

nullThis utility model takes techniques below scheme to realize: a kind of flame-retardant pull tension flexible cable，It is by conductor thread core、Four silver-plated copper metal hoses and six layers of external protection composition，Six layers of external protection are followed successively by layer of polyester fiber from inside to outside、Tin plating nickel strap armor、Zinc-plated aluminium strip screen layer、Nickel strap screen layer、Nonmagnetic metal armor and tin-coated copper strip armouring second propylene restrictive coating，Conductor thread core is aluminium alloy conductor core，Arrange four groups，Uniformly it is extruded in inside layer of polyester fiber with four silver-plated copper metal hoses，Described aluminium alloy conductor core is by nine aluminium alloy conductors、Four tin plating nickel wire drainage threads、A piece silver-plated tensile steel wire、Perfluoroethylene-propylene insulating barrier and polytetrafluoro polyolefin insulation layer composition，Nine aluminium alloy conductors and four tin plating nickel wire drainage threads are uniformly extruded in inside perfluoroethylene-propylene insulating barrier，In outward in described silver-plated tensile steel wire is extruded in polytetrafluoro polyolefin insulation layer and through polytetrafluoro polyolefin insulation layer.

One layer of butyronitrile insulating barrier, tin plating one layer of butyronitrile insulating barrier of nickel wire drainage thread outer wrapping is extruded outside described silver-plated copper metal hose.

This utility model has the advantages that this kind of cable waterproof is high temperature resistant in sum, and anti-flammability is strong, and pull resistance is strong, and light, soft.

Detailed description of the invention

nullAs shown in Figure 1，A kind of flame-retardant pull tension flexible cable，It is by conductor thread core、Four silver-plated copper metal hoses 2 and six layers of external protection composition，Six layers of external protection are followed successively by layer of polyester fiber 3 from inside to outside、Tin plating nickel strap armor 4、Zinc-plated aluminium strip screen layer 5、Nickel strap screen layer 6、Nonmagnetic metal armor 7 and tin-coated copper strip armouring second propylene restrictive coating 8，Conductor thread core is aluminium alloy conductor core 1，Arrange four groups，Layer of polyester fiber 3 inside uniformly it is extruded in four silver-plated copper metal hoses 2，Described aluminium alloy conductor core 1 is by nine aluminium alloy conductors 11、Four tin plating nickel wire drainage threads 12、A piece silver-plated tensile steel wire 13、Perfluoroethylene-propylene insulating barrier 14 and polytetrafluoro polyolefin insulation layer 15 form，Nine aluminium alloy conductors 11 and four tin plating nickel wire drainage threads 12 are uniformly extruded in perfluoroethylene-propylene insulating barrier 14 inside，In outward in described silver-plated tensile steel wire 13 is extruded in polytetrafluoro polyolefin insulation layer 15 and through polytetrafluoro polyolefin insulation layer 15，A part for the most silver-plated tensile steel wire 13 is positioned at layer of polyester fiber 3.

Detailed description of the invention: extrude one layer of butyronitrile insulating barrier, tin plating one layer of butyronitrile insulating barrier of nickel wire drainage thread 12 outer wrapping outside described silver-plated copper metal hose 2.

Further, the tin plating nickel strap armor 4 of the outer wrapping of described layer of polyester fiber 3 one layer, the zinc-plated aluminium strip screen layer 5 of outer wrapping one layer of described tin plating nickel strap armor 4, one layer of nickel strap screen layer 6 of outer wrapping of described zinc-plated aluminium strip screen layer 5, one layer of nonmagnetic metal armor 7 of the outer wrapping of described nickel strap screen layer 6, one layer of tin-coated copper strip armouring second propylene restrictive coating 8 of the outer wrapping of described nonmagnetic metal armor 7.

The above is this utility model embodiment, therefore all equivalence changes done according to structure, feature and the principle described in this utility model application range or modification, all it is included in this utility model patent claim.
