Abstract
The utility model discloses an environment protecting fireproof cable, wherein a cable core of the environment protecting fireproof cable are made by twisting multiple insulation wire cores (9), a gap among the insulation wire cores (9) is provided with a fiberglass filler (4), a glass fiber band (5) is wound around the cable core, a crosslinked polyethylene inner protection layer (6) is wrapped around the glass fiber tape (5) in an extruding manner, a copper band (7) is wound around the crosslinked polyethylene inner protection layer (6), and a halogen free low smoke polyethylene outer protection sleeve (8) is wrapped around the copper band (7) in an extruding manner. The environment protecting fireproof cable in the utility model is advantaged by reasonable structure, safety, environmental protection, fireproof function, and escape and rescue time increasing function.
Description
Technical field
The utility model 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.).
The utility model content
Technical problem to be solved in the utility model 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 utility model solves the problems of the technologies described above with following technical scheme:
The cable core of the utility model environmental-protection fireproof cable 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 the utility model environmental-protection fireproof cable 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 the utility model environmental-protection fireproof cable, 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 utility model.
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 utility model will be further described below in conjunction with accompanying drawing.
The cable core of the utility model environmental-protection fireproof cable 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 described in the utility model 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 fill in the space of the utility model between insulated wire cores, it does not burn.
The utility model is at the outer wrapped glass fiber tape of cable core, and it does not burn.
The crosslinked polyethylene sheath that the utility model adopts, it can not produce smog and pernicious gas when burning.
The utility model 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 utility model 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.
