Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
Given by figure 1 and figure 2, a fire-retardant explosion-proof cable for explosive place, including interior inoxidizing coating 4, its characterized in that, the inside steel core 1 that is equipped with the coaxial line of interior inoxidizing coating 4, be equipped with multiunit cable core between interior inoxidizing coating 4 and the steel core 1, the outside that interior inoxidizing coating 4's outside was equipped with shielding layer 6 and shielding layer 6 is equipped with fire-retardant layer 7, waterproof layer 8 and outer inoxidizing coating 9 from inside to outside in proper order, the outside of interior inoxidizing coating 4 is equipped with the resistance to compression subassembly that the multiunit distributes along the axis circumference array of steel core 1, a plurality of resistance to compression subassemblies all include with outer inoxidizing coating 9 between fixed connection's spring 11, spring 11 keeps away from one of outer inoxidizing coating 9 and serves and all is fixed with resistance to compression board 12, the outside of outer inoxidizing coating 9 is equipped with flame retardant coating.
This device is when using, at first lays this device in the position that needs work, and steel core 1 can improve the tensile strength ability of cable when using, and steel core 1 can effectually offset the injury of pulling force to inside cable core, and the shielding layer 6 of interior inoxidizing coating 4 outside can shield its inside cable core, avoids external magnetic field to produce the interference to it. 6 outside fire-retardant layer 7 of shielding layer can play fire-retardant effect, and waterproof layer 8 can be to the interference of sleet weather to the cable, and outer lag can protect the internals, can carry out frictional bearing and the protection of internals simultaneously when transport and installation. Under the effect of resistance to compression subassembly for the cable can carry out effectual offset to the pressure of outside and the vibrations that the explosion produced, avoids causing the harm to the cable of inside, improves the life-span of cable. When the fire-proof layer 10 on the outside of the cable is covered by fire, the fire-proof layer 10 is broken, and the pressure-resistant plate 12 pushes the fire-proof layer 10 on fire under the action of the internal spring 11, so that the fire-proof layer 10 with fire on the outside is separated from the main body of the cable, and the main body of the cable is protected. The using effect of the device is further improved.
And flame-retardant coatings are coated on the outer parts of the outer protective layer 9 and the fireproof layer 10.
The fire-proof paint is a special paint which is used on the surface of flammable base material, can reduce the flammability of the surface of the material to be painted, can retard the rapid spread of fire and is used for improving the fire endurance of the material to be painted.
