Preferably, described wire adopts that many copper free wires are stranded to be made.
Preferably, described mineral compound packing material adopts glass fibre to make.
Preferably, described lapping layer adopts glass fiber tape.
Preferably, described lubricant film adopts talcum powder thin layer.
In the present invention, the wire outside coated ceramic chemoprevention fire-resistant composite band cost of fire is low, insulativity and mechanicalness good, resilient flexible is good at normal temperatures for it, and is sintered into pottery armouring, excellent fireproof performance when burning, and burning does not come off; Filling mineral compound packing material between conductor, strengthens the fire resistant performance of cable; In cable, packing material and lapping layer all adopt fire retardant material to make, and insulation layer and interior sheath and oversheath adopt low smoke and zero halogen cross-linked polyolefin to make, make cable does not comprise the easily combustion-supporting material of combustion, thus there is good fire prevention resistivity against fire and erosion resistance; Lubricant film is set between interior sheath and oversheath, adds flexibility and the flexible of cable, simultaneously when presence of fire so that oversheath is easily from cable stripping, and protection inner conductor is not damaged.
In the preferred version of the present invention, packing material and lapping layer all adopt glass fibre to make, and its good insulating, thermotolerance are strong, erosion resistance good, physical strength height, further enhancing the high-temperature resistant anti-corrosive fire resistance of cable; Adopt talcum powder layer as lubricant film, its chemical torpescence, oilness, anti-stick glutinous, fireinsulation line excellence so that cable is ensureing to work safer under flexible and high temperature resistant prerequisite.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anticorrosion fire prevention insulated by oxide cable of a kind of super flexible high-temperature resistant that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the anticorrosion fire prevention insulated by oxide cable of a kind of super flexible high-temperature resistant that the present invention proposes.
With reference to Fig. 1, the anticorrosion fire prevention insulated by oxide cable of the super flexible high-temperature resistant of one that the present invention proposes, comprises four conductors 1.
Each conductor 1 inside comprises that many copper free wires are stranded and the wire 11 that becomes, the wire 11 outside wrapped pottery chemoprevention fire-resistant composite band 12 of fire. The insulation layer 13 that the pottery chemoprevention fire outside coated low smoke and zero halogen cross-linked polyolefin of fire-resistant composite band 12 is made, insulation layer 13 makes mutually insulated between conductor 1.
Four conductors 1 are spaced and parallel longitudinal in glass fiber material 2, form the cable core that cross section is circle, at the outside coated glass fiber tape 3 of cable core.
At the outside coated interior sheath 4 of glass fiber tape 3 and oversheath 6, interior sheath 4 and oversheath 6 all adopt low smoke and zero halogen cross-linked polyolefin to make, this kind of material has nontoxic, high temperature resistant, rot-resistant premium properties, and the effect of its cigarette fire-retardant, low is very remarkable, the anticorrosion damp-proof wear-resistant of this kind of double layer rubber sleeve form enhancing cable simultaneously. Talcum powder thin layer 5 is set between interior sheath 4 and oversheath 6 as lubricant film.
In cable works, glass fibre packing material 2 and glass fiber tape 3 have the performances such as insulation high-temperature-resistant, strengthen the flame-resistant high-temperature-resistant of cable, and the two, under the prerequisite of flexibility not affecting cable, enhances the tensile strength of cable simultaneously. When cable at high temperature burns, the pottery chemoprevention fire-resistant composite band 12 of fire can by Low fire ceramic armouring, and its crust property is good, excellent fireproof performance, and burning does not come off. Talcum powder thin layer 5 as lubricant film, its chemical torpescence, oilness, anti-stick glutinous, fireinsulation line excellent; make to lubricate very much between internal layer cover 4 and oversheath 6; when oversheath 6 is subject to twisting force, sheath 4 and inner conductor 1 in protection further, it is to increase the warp resistance of cable. Meanwhile, when wireline environment presence of fire, talcum powder thin layer 5 makes oversheath 6 easily from cable stripping, and protection inner conductor is not damaged further. In addition, insulation layer 13, interior sheath 4 and oversheath 6 that the pottery chemoprevention fire-resistant composite band 12 of fire, glass fibre packing material 2, glass fiber tape 3, low smoke and zero halogen cross-linked polyolefin are made and talcum powder thin layer 5 are fire-retardant fireproof high temperature material, make cable does not comprise the easily combustion-supporting material of combustion, thus there is excellent fire-retardant fireproof high thermal resistance and erosion resistance.
Preferably, the fire-resistant composite band 12 of pottery chemoprevention fire comprises following component according to mass fraction: 100-130 part silicon rubber, 10-18 part nano-calcium carbonate, 8-12 part carbon fiber, 0.5-1 part coupling agent M320,0.8-1.2 part hydroxy silicon oil; Specifically, 100 parts of silicon rubber, 15 parts of nano-calcium carbonates, 10 parts of carbon fibers, 0.5 part of coupling agent M320,1 part of hydroxy silicon oil. Insulativity and the mechanicalness of this kind of ceramic chemoprevention fire-resistant composite band 12 of fire are good, and resilient flexible is good at normal temperatures, and vertical bag is all very excellent with wrapped compactness and stopping property. When cable burns, its Fast Sintering becomes pottery armouring, excellent fireproof performance, and burning does not come off. In addition, the mica tape that the price of the pottery chemoprevention fire-resistant composite band 12 of fire uses lower than routine, saves the cost of cable further.
The anticorrosion fire prevention insulated by oxide cable of super flexible high-temperature resistant according to the present embodiment, after testing, voltage range is 0.6/1kV; Withstand voltage test is 3.5/5kV/min; Conductor long term operation temperature is 250 DEG C; Overload capacity can reach more than 100 times of normal current capacity; Current capacity can improve same uniform cross section current capacity shelves; Waterproof anti-explosion performance is good, fire resistance is good; Safety, environmental protection, life-span are long, and burning also can not produce smog, halogen and toxic gas; Good bending property, and there is good ground connection (bending radius 8D).
The above; it is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the present invention discloses; technical scheme and invention design thereof according to the present invention are equal to replacement or are changed, and all should be encompassed within protection scope of the present invention.
