Abstract
The invention discloses an environment-friendly fireproof cable. A core of the environment-friendly fireproof cable is formed by twisting a plurality of insulating core wires (9), gaps among the insulating core wires (9) are filled with glass fiber filling (4). The core is wrapped with a glass fiber tape (5), a cross-linked polyethylene inner sheath layer (6) is extruded on the glass fiber tape (5) and is wrapped with a copper tape (7), and a halogen-free low-smoke polyethylene outer sheath (8) is extruded on the copper tape (7). The environment-friendly fireproof cable is more structurally reasonable, safer and more environment-friendly, and has the functions of proofing fire and prolonging escape and rescue time.
Description
Technical field
The present invention relates to technical field of electric wires and cables, specifically a kind of environmental-protection fireproof cable.
Background technology
At present usually can add some inorganic combustion inhibitors in macromolecular material pvc material used when the insulation of making cable and sheath; as add the fire retardants such as aluminium hydroxide, magnesium hydroxide to improve the fire resistance of material; but adding of these inserts is limited, adds these materials can reduce electric property and the mechanical and physical performance of cable.If add too much, can't satisfy instructions for use.Although added these inorganic anti-flaming materials, under flame condition, cable still can burn having, and also can emit harmful substance and smog during burning.Cable sheath material and inserts can be added some fire retardants, but for cable insulating material used, in order to guarantee electric property, can only add less fire retardant.The so-called environment-friendly cable auxiliary material such as insulating material, sheath material and filling used itself are the macromolecule chemical industry materials in the market, or can burn, in case breaking out of fire, so-called environment-friendly cable still can be lighted raging flames, and discharge a large amount of dense smokes and harmful substance, make people be subject to sootiness and death by suffocation, the serious harm people security of the lives and property.Also can produce electromagnetic radiation to surrounding environment in present environment-friendly cable running, affect especially some weak electric signal equipment and normally use (as the sonwflake phenomenon that produces in video monitoring system, Internet Transmission interference etc.).
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of rational in infrastructure, safety, environmental protection, fire prevention, increase escape and the environment-friendly cable of rescue time.
The present invention solves the problems of the technologies described above with following technical scheme:
The cable core of environmental-protection fireproof cable of the present invention is to consist of by several insulated wire cores are stranded, there is the glass fiber filler in space between insulated wire cores, wrapped glass fiber tape on cable core, extrude one deck crosslinked polyethylene sheath on glass fiber tape, wrapped copper strips on the crosslinked polyethylene sheath extrudes low smoke, zero halogen outer protective polyethylene cover on copper strips.
The insulated wire cores of environmental-protection fireproof cable of the present invention is to be made of copper conductor, fire-resistant isinglass belt and crosslinked polyetylene insulated layer, and fire-resistant isinglass belt is wrapped on copper conductor, and crosslinked polyetylene insulated layer is extruded on fire-resistant isinglass belt.
The more reasonable structure of environmental-protection fireproof cable of the present invention, safer, more environmental protection have fire prevention, increase escape and the function of lifesaving time.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure: copper conductor 1, fire-resistant isinglass belt 2, crosslinked polyetylene insulated layer 3, glass fiber filler 4, glass fiber tape 5, crosslinked polyethylene sheath 6, copper strips 7, low smoke, zero halogen outer protective polyethylene cover 8, insulated wire cores 9.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The cable core of environmental-protection fireproof cable of the present invention is to consist of by several insulated wire cores 9 are stranded, every eradication edge core 9 is to be made of copper conductor 1, fire-resistant isinglass belt 2 and crosslinked polyetylene insulated layer, fire-resistant isinglass belt 2 is wrapped at copper conductor 1, and crosslinked polyetylene insulated layer 3 is extruded on fire-resistant isinglass belt 2.There is glass fiber filler 4 in space between insulated wire cores 9, wrapped glass fiber tape 5 on cable core, extrude one deck crosslinked polyethylene sheath 6 on glass fiber tape 5, wrapped copper strips 7 on crosslinked polyethylene sheath 6 extrudes low smoke, zero halogen outer protective polyethylene cover 8 on copper strips 7.
The fire-resistant isinglass belt that insulated wire cores of the present invention adopts has good fireproofing function, at high temperature do not burn, keeping fire protecting performance, is being 90 minutes for the fire time, under rated voltage 0.6/1KV condition, the 2A fuse is continuous, indicator light does not put out, and common cable does not reach this requirement, when greatly having improved the fire generation, the escape and rescue time is for life has won the time.
The glass fiber that the present invention fills in the space between insulated wire cores, it does not burn.
The present invention is at the outer wrapped glass fiber tape of cable core, and it does not burn.
The crosslinked polyethylene sheath that the present invention adopts, it can not produce smog and pernicious gas when burning.
The present invention's wrapped copper strips on sheath, it does not burn, and fusing point is: 1083 ℃, has the function of not burning, cut off flare and inner polyethylene and insulation, and have the shielding anti-electromagnetic radiation function, and be nonmagnetic substance, cable inside can not produce vortex phenomenon.
The low smoke, zero halogen outer protective polyethylene layer that the present invention adopts, it is in when burning, produce the cigarette of minute quantity and light transmission good, can not produce pernicious gas, this is just convenient when fire occurs, avoid by sootiness and lost or by sootiness and death by suffocation provides favourable assurance when being subjected to the danger for life.
