Description
Technical field
The present invention relates to elevator cable field, specifically, be related specifically to a kind of explosion-proof elevator cable for fire protection.
Background technology
Existing cable, is provided with insulating barrier outside core, coated by coating layer in periphery, is sheath outside coating layer, the structure of this cable is simple, but shield effectiveness is poor, and tensile strength is also undesirable, not there is explosion prevention function, easily produce and put point, leaky, there is serious potential safety hazard.
Some there is explosion hazard and explosion-proof security require higher place, such as, offshore oil platform, oiling, gas station etc., conventional cable transmits automatic control signal, and current used cable, still common cable is adopted, all requirement is not done to explosion-proof performance, structure specify only the thinnest point of insulation, material is common material, cannot requirement of explosion proof be reached, existing cable only specifies that shielding density requirements does not have drainage measure simultaneously, can not stop interference completely.
Summary of the invention
The object of the present invention is to provide a kind of explosion-proof elevator cable for fire protection, by carrying out structural improvement to traditional cable, overcoming the deficiency in conventional art, meeting the demand in market, thus realize object of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of explosion-proof elevator cable for fire protection, comprises cable conductor, elasticity packed layer, inner sheath, Anti-pull-press layer, metal screen layer and oversheath; Described cable conductor comprises some independently control lines, power line and multiple twin communication converting video line; described control line, power line and multiple twin communication converting video line are provided with elasticity packed layer; inner sheath is had in the outer wrap of elasticity packed layer; for internal layer protection cable conductor; the outside of described inner sheath set gradually be improved resistance Anti-pull-press layer, for the metal screen layer that prevents radiation from leaking with for preventing the oversheath of physical injury, being provided with between metal screen layer and oversheath and being provided with flame-proof explosion-proof layer.
In one embodiment of the invention, described control line, power line and multiple twin communication converting video line are provided with a pair.
In one embodiment of the invention, described metal screen layer comprises the steel belt layer of inner side and the steel wire floor in outside.
In one embodiment of the invention, the two ends of described explosion-proof elevator cable for fire protection cable in use respectively configure a set of impedance transducer realizing video communication function.
Beneficial effect of the present invention is: metal screen layer of the present invention is provided with flame-proof explosion-proof layer, oversheath adopts wear-resisting, resistance to chemical attack, the protection of resistant to elevated temperatures fluoroplastics, oversheath has to pass through " encapsulation " PROCESS FOR TREATMENT man-hour adding, and " encapsulation " technological requirement outer jacket must stand 180 DEG C of curing times of three hours.Because outer jacket and sheath have good effect of heat insulation, cause internal core not impaired.
Due to the coaxial line that usual video line is XLPE or foaming PE material, temperature more than 90 DEG C or 60 DEG C time, stand within 2 hours, to cause video line to insulate cannot be out of shape by recovery, require so that product performance impedance does not reach and lose product function, now take multiple twin communication converting video line to substitute, the impedance transducer respectively configuring a set of independent research at the two ends of cable realizes video communication function.
Cable conductor of the present invention can be avoided leaking electricity and be put the generation of a phenomenon, electromagnetic interference can be avoided simultaneously, structure is simple, have steel belt layer, bear pressure result good, external force resistance effect is strong, be applicable to the processing of encapsulation technology, can prevent spark point between cable and connector from igniting imflammable gas, multiple twin communication converting video line can run continuously under long-time high temperature simultaneously, and explosion-proof effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of explosion-proof elevator cable for fire protection of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, explosion-proof elevator cable for fire protection of the present invention, it comprises cable conductor 100, elasticity packed layer 120, inner sheath 130, Anti-pull-press layer 140, metal screen layer 150 and oversheath 160, cable conductor 100 comprises some independently control lines 101, power line 102 and multiple twin communication converting video line 103, control line 101, power line 102 and multiple twin communication converting video line 103 are provided with elasticity packed layer 120, inner sheath 130 is had in the outer wrap of elasticity packed layer 120, for internal layer protection cable conductor, the outside of inner sheath 130 sets gradually the Anti-pull-press layer 140 being improved resistance, the metal screen layer 150 leaked for preventing radiation and for preventing the oversheath 160 of physical injury, be provided with between metal screen layer 150 and oversheath 160 and be provided with flame-proof explosion-proof layer 170.
In an embodiment of the present invention, in order to better realize the performance of cable conductor 100, control line 101, power line 102 and multiple twin communication converting video line 103 are provided with a pair.
Especially it is pointed out that to better prevent the radiation of inside cable cable core 100 from leaking, metal screen layer 150 comprises the steel belt layer of inner side and the steel wire floor in outside.
The flame-proof explosion-proof layer 170 established between metal screen layer 150 and oversheath 160, oversheath 160 adopts wear-resisting, resistance to chemical attack, the protection of resistant to elevated temperatures fluoroplastics, oversheath 160 has to pass through " encapsulation " PROCESS FOR TREATMENT man-hour adding, and " encapsulation " technological requirement outer jacket must stand 180 DEG C of curing times of three hours.Because outer jacket 160 and inner sheath 130 have good effect of heat insulation, cause internal core not impaired.
Due to the coaxial line that usual video line is XLPE or foaming PE material, temperature more than 90 DEG C or 60 DEG C time, stand within 2 hours, to cause video line to insulate cannot be out of shape by recovery, require so that product performance impedance does not reach and lose product function, now take multiple twin communication converting video line to substitute, the impedance transducer respectively configuring a set of independent research at the two ends of cable realizes video communication function.
