Abstract

The utility model discloses a flame retarded cable for fire control, it comprises conductor sinle silk, silver -plated copper metal collapsible tube and four layers external coating. Four layers external coating is by interior and be silicone rubber insulating layer, zinc -plated aluminium strip armor, silver -plated aluminium strip shielding layer and zinc -plated nickel strap armor polyolefin restrictive coating outward in proper order, and the conductor sinle silk is the copper conductor sinle silk, set up two sets of, even crowded package inside silicone rubber insulating layer, the crowded package six roots of sensation of conductor in the copper conductor sinle silk, silvering copper metal collapsible tube is crowded to be wrapped between two sets of copper 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-fighting flame retardant cable

Technical field

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

nullThis utility model takes techniques below scheme to realize: a kind of fire-fighting flame retardant cable，It is by conductor thread core、A piece silver-plated copper metal hose and four layers of external protection composition，Four layers of external protection are followed successively by silicone rubber insulation layer from inside to outside、Tin plating aluminium strip armor、Silver-plated aluminium strip screen layer and zinc-plated nickel strap armouring polyolefin sheath layer，Four nickel wire drain silks are uniformly extruded between described tin plating aluminium strip armor and silver-plated aluminium strip screen layer，Conductor thread core is copper conductor core，Arrange two groups，Uniformly it is extruded in inside silicone rubber insulation layer，Described copper conductor core is by six roots of sensation copper conductor、One layer of nonmagnetic metal armor、One layer of zinc-plated silver-plated aluminium strip screen layer、One layer of low smoke and zero halogen pe sheath layer、A piece silver coated aluminum alloy drainage thread and an aluminium wire drainage thread composition，Silver coated aluminum alloy drainage thread pierces into low smoke and zero halogen pe sheath layer、Silicone rubber insulation layer and tin plating aluminium strip armor，Aluminium wire drainage thread pierces into low smoke and zero halogen pe sheath layer and silicone rubber insulation layer，Described silver-plated copper metal hose is extruded between two groups of copper conductor cores and pierces into the low smoke and zero halogen pe sheath layer of two groups of copper conductor cores，A silver-plated steel band tension silk is extruded between described zinc-plated silver-plated aluminium strip screen layer and low smoke and zero halogen pe sheath layer.

Described silver coated aluminum alloy drainage thread and aluminium wire drainage thread cross-sectional diameter a length of 0.60.

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.
