In the utility model, the outside coated ceramic fireproof composite band cost of wire is low, insulating properties and mechanicalness good, resilient flexible is good at normal temperatures for it, and is sintered into pottery armouring in the time of burning, fire resistance excellence, burning does not come off; Filling mineral compound packing material between conductor, the fire resistant performance of enhancing cable; In cable, packing material and lapping layer all adopt fire proofing to make, and insulating barrier and inner sheath and oversheath adopt low smoke and zero halogen cross-linked polyolefin to make, make not comprise in cable inflammable combustion-supporting material, thereby there is good fireproof and corrosion resistance; Between inner sheath and oversheath, lubricating layer is set, has increased flexibility and the flexible of cable, in the time of breaking out of fire, make oversheath easily from cable stripping simultaneously, protection inner conductor is not damaged.
In preferred version of the present utility model, packing material and lapping layer all adopt glass fibre to make, and its good insulating, thermal endurance is strong, corrosion resistance good, and mechanical strength is high, has further strengthened the high-temperature resistant anti-corrosive fire protecting performance of cable; Adopt talcum bisque as lubricating layer, its chemistry torpescence, lubrification, anti-stick glutinous, slow-burning wire is excellent, and cable under flexible and resistant to elevated temperatures prerequisite, is worked safer ensureing.
Brief description of the drawings
Fig. 1 is the structural representation of the anticorrosion fire prevention insulated by oxide of a kind of super flexible high-temperature resistant cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the anticorrosion fire prevention insulated by oxide of a kind of super flexible high-temperature resistant cable that the utility model proposes.
With reference to Fig. 1, the anticorrosion fire prevention insulated by oxide of the super flexible high-temperature resistant of the one cable the utility model proposes, comprises four conductors 1.
Each conductor 1 inside comprises the many stranded wires that form 11 of copper free wire, the outside wrapped ceramic fireproof composite band 12 of wire 11.The insulating barrier 13 that the outside coated low smoke and zero halogen cross-linked polyolefin of ceramic fireproof composite band 12 is made, insulating barrier 13 makes mutually insulated between conductor 1.
Four conductor 1 spaces parallel vertical putting in glass fiber material 2, forming cross section is circular cable core, at the outside coated glass fiber tape 3 of cable core.
At the outside coated inner sheath 4 of glass fiber tape 3 and oversheath 6, inner sheath 4 and oversheath 6 all adopt low smoke and zero halogen cross-linked polyolefin to make, this material has nontoxic, high temperature resistant, corrosion-resistant premium properties, and it is fire-retardant, the effect of low cigarette is very remarkable, simultaneously this duplex sheath form strengthens the anticorrosion damp-proof wear-resistant of cable.Between inner sheath 4 and oversheath 6, talcum powder thin layer 5 is set as lubricating layer.
In cable work, 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 has strengthened the tensile strength of cable under the flexible prerequisite that does not affect cable simultaneously.In the time that cable at high temperature burns, ceramic fireproof composite band 12 can be by Low fire ceramic armouring, and its crust property is good, fire resistance excellence, and burning does not come off.Talcum powder thin layer 5 is as lubricating layer, its chemistry torpescence, lubrification, anti-stick glutinous, slow-burning wire is excellent; make between internal layer cover 4 and oversheath 6 very lubricated; in the time that oversheath 6 is subject to twisting force, further protect inner sheath 4 and inner conductor 1, improve the warp resistance of cable.Meanwhile, in the time of wireline environment breaking out of fire, talcum powder thin layer 5 makes oversheath 6 easily from cable stripping, further protects inner conductor not to be damaged.In addition, insulating barrier 13, inner sheath 4 and oversheath 6 and talcum powder thin layer 5 that ceramic fireproof composite band 12, glass fibre packing material 2, glass fiber tape 3, low smoke and zero halogen cross-linked polyolefin are made are fire-retardant fireproof exotic material, make not comprise in cable inflammable combustion-supporting material, thereby there is excellent fire-retardant fireproof heat-resisting quantity and corrosion resistance.
Preferably, ceramic fireproof composite band 12 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; Particularly, 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.Insulating properties and the mechanicalness of this ceramic fireproof composite band 12 are good, and resilient flexible is good at normal temperatures, and vertical bag and wrapped compactness and sealing are all very excellent.In the time of cable fire, its Fast Sintering becomes pottery armouring, fire resistance excellence, and burning does not come off.In addition, the price of ceramic fireproof composite band 12, lower than the mica tape of routine use, has further been saved the cost of cable.
According to the anticorrosion fire prevention insulated by oxide of the super flexible high-temperature resistant cable of the present embodiment, after testing, electric pressure is 0.6/1kV; Withstand voltage test is 3.5/5kV/min; Conductor long-term work temperature is 250 DEG C; Overload capacity can reach the more than 100 times of normal ampacity; Ampacity can improve shelves of same uiform section ampacity; Waterproof anti-explosion performance is good, fire protecting performance is good; Safety, environmental protection, life-span are long, and burning can not produce smog, halogen and toxic gas yet; Good bending property, and there is good ground connection (bending radius 8D).
