Abstract
The utility model relates to a cable, in particular to a light flame-retardant cable, which comprises an outer insulating layer, an inner insulating layer and a core. A flame retardant layer is arranged between the outer insulating layer and the inner insulating layer, flame retardant filling is arranged between the inner insulating layer and the core, and the flame retardant layer is filled with inert gas. With the adopted technical scheme, the light flame-retardant cable has the advantages of light self weight, strong flame retardant capacity and the like.
Description
Technical field
The utility model relates to cable, is specifically related to light, the flame retardant cable of a kind of own wt.
Background technology
Cable is the main mode of dispensing electrical transmission, and along with development and national economy, the cable demand increases year by year.At the bottom of ground, the ocean, be provided with cable everywhere in the air, it brings huge help for our life and work electricity consumption.
Because it much is flammable that the manufactured materials of cable has, cable also becomes one of root of breaking out of fire.Therefore, have the flame retardant cable of numerous model structures on the market, but the flame retardant cable of conventional art nearly all is to adopt the structural design of common cable to add what fire proofing formed, certainly will also increase the cable own wt in fire-retardant.
Though these cables have increased the material of flame-retardant in cable, but after the long-time burning of these flame-retardant materials, breaking also can appear in cable jacket, and has smog during burning, even can discharge toxic and harmful, also can't stop the burning of flame to the cable internal layer.
The utility model content
The purpose of this utility model is, a kind of light flame-retardant cable is provided, and solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The light flame-retardant cable comprises external insulation layer, inner insulating layer, cable core, it is characterized in that, is provided with flame-retardant layer between described external insulation layer and the inner insulating layer, is provided with fire-retardant filler between described inner insulating layer and the cable core, is filled with inert gas in the described flame-retardant layer.
Inert gas is not only stable, in light weight, and can effectively stop flame invasion inner insulating layer.
Advantages such as described external insulation layer and described inner insulating layer all adopt the flame-proof silicon rubber material, and it is fire-retardant, water-fast, wear-resisting that flame-proof silicon rubber has.
Described fire-retardant filler is the flame-retardant low-smoke halogen-free filler, can realize fire-retardant purpose, because not halogen-containing toxigenicity does not again contain heavy metal, and environmental protection, harmless to health.
In case light flame-retardant cable breaking out of fire; the flame external insulation layer that burns for a long time; after in case breaking appears in external insulation layer; flame enters flame-retardant layer; the inert gas of flame-retardant layer is as the fire retardant knock down the flame; the utility model is handicapping combustion filler in inner insulating layer also, reaches the dual fire-retardant effect of preventing, protecting cable core.
Beneficial effect:, the utlity model has advantages such as own wt is light, fire retardancy is strong owing to adopted technique scheme.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, the light flame-retardant cable comprises external insulation layer 1, inner insulating layer 3, cable core 5, is provided with flame-retardant layer 2 between external insulation layer 1 and the inner insulating layer 3, is provided with fire-retardant filler 4 between inner insulating layer 2 and the cable core 5, is filled with inert gas in the flame-retardant layer 2.Inert gas can be inert gases such as helium, neon.It is not only stable, in light weight to fill inert gas, and can effectively stop flame invasion inner insulating layer.
Advantages such as external insulation layer 1 and inner insulating layer 3 all adopt the flame-proof silicon rubber material, and it is fire-retardant, water-fast, wear-resisting that flame-proof silicon rubber has.Fire-retardant filler 4 is the flame-retardant low-smoke halogen-free filler, can realize fire-retardant purpose, because not halogen-containing toxigenicity does not again contain heavy metal, and environmental protection, harmless to health.
In case light flame-retardant cable breaking out of fire; the flame external insulation layer that burns for a long time; after in case breaking appears in external insulation layer; flame enters flame-retardant layer; the inert gas of flame-retardant layer is as the fire retardant knock down the flame; the utility model is handicapping combustion filler in inner insulating layer also, reaches the dual fire-retardant effect of preventing, protecting cable core.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
