Four layers external coating is by interior and outward in proper order for gathering the second propylene insulating layer of perfluor, zinc -plated nickel strap armor, nickel strap shielding layer and zinc -plated nickel strap armor pe sheath layer, two kinds of conductor sinle silks are plating aluminium -zinc alloy conductor sinle silk and silver -plated aluminum alloy conductor sinle silk respectively, respectively set up two sets of, all even crowded package inside gathering the second propylene insulating layer of perfluor, the crowded bao bagen of conductor in the plating aluminium -zinc alloy conductor sinle silk, the crowded bao bagen of conductor in the silvering aluminum alloy conductor sinle silk, silvering copper metal collapsible tube is crowded to be wrapped between two sets of plating aluminium -zinc alloy conductor sinle silks and pierces into the outmost of them. 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 fire-retardant leading cable of fire-fighting

Technical field

This utility model belongs to field of cables, particularly relates to a kind of fire-retardant leading cable of fire-fighting.

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 a center; 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, the fire-retardant leading cable of fire-fighting.

nullThis utility model takes techniques below scheme to realize: a kind of fire-retardant leading cable of fire-fighting，It is by two kinds of conductor thread cores、A piece silver-plated copper metal hose and four layers of external protection composition，Four layers of external protection are followed successively by perfluoroethylene-propylene insulating barrier from inside to outside、Tin plating nickel strap armor、Nickel strap screen layer and zinc-plated nickel strap armouring pe sheath layer，Two kinds of conductor thread cores are respectively zinc-aluminium-alloy conductor thread core and silver coated aluminum alloy conductor core，Respectively arrange two groups，The most uniformly it is extruded in inside perfluoroethylene-propylene insulating barrier，Described zinc-aluminium-alloy conductor thread core is by eight zinc-aluminium-alloy conductors、One layer of chloroprene rubber sheath layer、One layer of zinc-plated nickel strap screen layer、One layer of low smoke and zero halogen pe sheath layer、A piece silver coated aluminum alloy drainage thread and a zinc-plated copper wire drainage thread composition，Silver coated aluminum alloy drainage thread pierces into low smoke and zero halogen pe sheath layer、Perfluoroethylene-propylene insulating barrier and tin plating nickel strap armor，Zinc-plated copper wire drainage thread pierces into low smoke and zero halogen pe sheath layer and perfluoroethylene-propylene insulating barrier，Described silver-plated copper metal hose is extruded between two groups of zinc-aluminium-alloy conductor thread cores and pierces into the low smoke and zero halogen pe sheath layer of two groups of zinc-aluminium-alloy conductor thread cores，Described silver coated aluminum alloy conductor core is by eight silver coated aluminum alloy conductors、One layer of tin plating aluminium strip armor、Aluminium strip screen layer and a silver-plated aluminium wire drainage thread composition，Described silver-plated aluminium wire drainage thread is positioned at aluminium strip screen layer and passes aluminium strip screen layer in perfluoroethylene-propylene insulating barrier.

Described one layer of butyronitrile insulating barrier of silver-plated copper metal hose outer wrapping.

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.
