As a kind of preferred technical scheme of the present invention, also it is installed between the cable inner core frame and center rest
The fire-retardant separation layers of PVC, the fire-retardant separation layers of PVC are annular in shape close close to center rest distribution.
As a kind of preferred technical scheme of the present invention, the uniform closed cable that is distributed in of the mica fireprotection layer equal in width is consolidated
Determine to be closed on frame and by cable fixed mount, and adjacent mica fireprotection layer arranged in parallel is but not directly contacted with each other.
As a kind of preferred technical scheme of the present invention, the band is made up of a series of aluminum alloy drawing lines, and aluminium is closed
Circular fix is wound in net distribution be attached to anti-flaming thermal-insulation layer outer surface between golden wire drawing line.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention by by cable inner core with pull rope and snap ring
Drawn and be fixedly mounted in cable fixed mount and center rest, carrying out resistance to burn on the outside of cable with mica fireprotection layer prevents
It is subject to again on the outside of fire, and mica fireprotection layer on anti-flaming thermal-insulation layer, and extinguishes fire by water reduction temperature is separated out, due to cloud
The fire resisting of parent material, resistance to thermal property, it is ensured that cable is also working properly in fire, sheath and outer jacket use fire proofing,
Can be further fire-retardant, be formed not only fire-retardant but also fire resisting cable, using multilayer mica tape directly the wrapped on wire it
Prolonged burning is resistant to, even if the high polymer applied at flame is burned out, also ensure that circuit is normally run.
