Abstract
The utility model provides an environment-friendly high flame resistant fireproof control cable used for a fire-fighting security system, relates to the technical field of cable manufacturing, and especially relates to the environment-friendly high flame resistant fireproof control cable used for a fire-fighting security system. The cable comprises four insulated wire cores. A columnar filler rope is disposed in a center of the four insulated wire cores. The four insulated wire cores and the columnar filler rope are stranded to form the cable. Outside the four insulated wire cores and the stranded columnar filler rope, a wrapping tape layer, an inner sheath layer, a copper braid shielding layer and an outer sheath layer are disposed in sequence. Each insulated wire core comprises at least a conductor, and a flame retardant coating, a protection layer, and an insulating layer are disposed outside the conductor in sequence. The cable has good fire resistance and flame retardance, and can still keep good dielectric strength at ignition temperature.
Description
Technical field
The utility model relates to the cables manufacturing technical field, relates in particular to fire-fighting security system high-flame-resistance environment-friendly fireproof control cable.
Background technology
Along with rapid development of science and technology, power consumption equipment in the various buildings is more and more, demands for higher performance to electric wire electricity border, because the loss that fire causes is increasing, the fire protecting performance of electric wire requires more and more outstanding, especially fire-fighting security keypoint part is even more important, such as the communication maincenter, the building ' s fire system, automatic alarm system, broadcasting equipment, the mercapto passage that looses, the escape hatch identification light, emergency elevator, important events such as commander's control maincenter, require cable to have LSOH anti-flaming performance and fire resistance especially, in a period of time that fire takes place, can the maintenance system normally move, make and throw light on, fireproof alarming device and other emergency set can continue energising, transmission of control signals within a certain period of time, in order to fire is taked corresponding measure, rescue work is normally carried out.Simultaneously, the toxicity of the seondary effect that fire brings such as casualties, combustion fumes and to the pollution of environment etc. causes the loss more serious than fire sometimes.
Summary of the invention
The utility model purpose is to provide a kind of low cigarette, Halogen, fire-retardant, nontoxic, environmental protection, temperature resistant grade height, fire-fighting security system environment-friendly high fire-retardant fireproof control cable that fail safe is good.
The utility model comprises that four thoroughly do away with the edge core, thoroughly do away with edge core center described four the column gasket for packing is set, described four thoroughly do away with edge core and the mutual stranded stranding of column gasket for packing, set gradually belting layer, inner restrictive coating, copper wire woven shield and external sheath layer in the four stranded outsides of thoroughly doing away with edge core and column gasket for packing; Every described insulated wire cores comprises at least one conductor respectively, sets gradually flame retardant coating, protective layer and insulating barrier in the described conductor outside.
Conductor material described in the utility model draws the lead that forms for the high-quality oxygen-free copper bar.Conductor should satisfy among the GB/T3956 the 1st, the performance requirement of 2 kind of conductor.Cross-sectional area of conductor is generally 1～10m ㎡.Flame retardant coating of the present utility model adopts the overlapping wrapped formation of multilayer synthetic mica tape, and wrapped Duplication is for being not less than 30%.The utility model flame retardant type filler is made of low-smoke non-halogen flame-retardant humatite rope, and fire-retardant band is made of the combustion-proof glass fiber strap, and the combustion-proof glass fiber strap can absorb a large amount of heats and can stop that flame passes, secluding air when suffering flame combustion.Inorganic fire-retarded complexing agent can dilute the crystallization water on the surface and reduce the heat invasion, and protection wire cable insulating layer is avoided burning.
The utlity model has good fire resistant flame retardant characteristic, and under ignition temperature, still can keep good dielectric strength, insulating barrier is cross-linking polyethylene materials, have excellent mechanical and physical performance, hot property and electrical property and fire resistance, restrictive coating is low smoke halogen-free flame-retardant polyolefin, and belting layer is fire-retardant Halogen non-toxic organic material, and the Halogen acid gas disengages during burning, the amount of being fuming is low, can not produce smog and have the very strong hydrogen halide of corrosivity of secondary disaster.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises that four thoroughly do away with edge core 1, at four centers of thoroughly doing away with edge core 1 column gasket for packing 2 is set, four thoroughly do away with edge core 1 and column gasket for packing 2 mutual stranded strandings, set gradually belting layer 3, inner restrictive coating 4, copper wire woven shield 5 and external sheath layer 6 in the four stranded outsides of thoroughly doing away with edge core 1 and column gasket for packing 2; Every eradication edge core 1 comprises at least one conductor 7 respectively, sets gradually flame retardant coating 8, protective layer 9 and insulating barrier 10 in conductor 7 outsides.
Claims (1)
