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.
