It is interior to be filled with fire retardant；It is described include crosslinked polyetylene insulated layer be disposed with from inside to outside sealant, separation layer and low cigarette without
Halogen polyolefin sheath layer；Fire-extinguishing mine is additionally provided with the crosslinked polyetylene insulated layer, the fire-extinguishing mine includes powdery structure shell
Body, apparatus to cause bursting and the blasting charge being sealingly disposed in powdery structure housing and safe gas bag, the apparatus to cause bursting include leading fire
Rope and detonator, the detonator are stretched into the blasting charge, the inner connection detonator of the fuse cord and safe gas bag, the fuse cord
Outer end is stretched out outside powdery structure housing and is engaged face with packed layer positioned at crosslinked polyetylene insulated layer.
As further program of the utility model：The sealant is wrapped, the described sealing of alkali-free glass fibre rope
Layer uses two layers.
As the utility model further scheme：The separation layer is inorganic alumine hydroxide colloid packed layer.
As the utility model further scheme：The powdery structure housing is to be extruded from by fire extinguishing powder.
Compared with prior art, the beneficial effects of the utility model are：Sealant and separation layer are set, when burning to isolation
During layer, the alumine hydroxide colloid of separation layer filling is heated after on fire can be separated out water and be attached to surface formation protective filmy layer,
Naked light is isolated, and sealant be alkali-free glass fibre rope it is wrapped, can by separation layer chemically react separate out water carry out every
From, prevent its to inside packed layer erode；Fire-extinguishing mine is set, when fire burning to crosslinking polyethylene layer and packed layer
During interface, fuse cord is lighted in flare contact so that safe gas bag and detonation of a cartridge, the driving fire extinguishing powder in the form of blast,
It is allowed to impact scattering suspension adhesion to be covered on cable fire point or burning zone and put out a fire, fire extinguishing is rapid, and area coverage is wide, effect
It is good；Low-smoke halogen-free polyolefin restrictive coating is set, and low smoke and zero halogen, harmful smoke is less during burning.
In summary, this new structural design is reasonable, low smoke and zero halogen, and reduction of speed is harmful to the generation of halogens flue gas；Pass through
The mode that separation layer separates out water realizes that the first weight is fire-retardant；Then the condition of a fire is responded within the shortest time by fire-extinguishing mine, with blast
Form driving fire extinguishing powder fire extinguishing, realize second rush it is fire-retardant；Ensure that cable is not burnt by the intensity of a fire well.
