Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the present invention provides a kind of technical solution: a kind of flame retardant cable, including inflaming retarding shell 1,
Dioxide capsule 2, carbon dioxide compression room 3, metal retaining wall 4, jet groove 5, air nozzle 6, sealing strip 7, dry powder floor 8, steel
Silk 9, asbestos insulating layer 10, vacuum layer 11, wire insulation 12 and wire stylet 13, the inflaming retarding shell 1 are equipped with carbon dioxide
Air bag 2, the density that the dioxide capsule 2 is arranged on cable are 2.5 meters one, it is ensured that fire-retardant effect, simultaneously
It is unlikely to cause excessive weight to oppress to cable again, carbon dioxide compression room 3, institute is equipped with inside the dioxide capsule 2
It states about 3 two sides of carbon dioxide compression room and is equipped with metal retaining wall 4, it is recessed to be equipped with jet at left and right sides of the carbon dioxide compression room 3
Slot 5, the jet groove 5 is interior to be equipped with air nozzle 6, and the jet groove 5 is covered by sealing strip 7, and the sealing strip 7 is inflammable modeling
Expect material, it is ensured that allow sealing strip 7 first to catch fire, then eliminate the blocking to jet thrust 6, it is enable to spray two in kindling
Carbonoxide is equipped with dry powder layer 8 on the inside of the inflaming retarding shell 1, steel wire 9 is equipped in the dry powder layer 8, is set on the inside of the dry powder layer 8
