Accompanying drawing explanation
Fig. 1 is that the cross-sectional structure of generation Ⅲ nuclear power station of the present invention hinge polyolefin insulation fire-proof medium-voltage cable shows
It is intended to；
Wherein, copper conductor 1, mica tape 2, inorganic fire-retarded layer 3, fire prevention mud layer 4, copper sheath 5, outer jacket 6, optical fiber cable 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As it is shown in figure 1, the generation Ⅲ nuclear power station of present invention hinge polyolefin insulation fire-proof medium-voltage cable, including meeting
The copper conductor that GB/T3956-2008 requires, extrudes polyolefin copolymer insulating barrier after described copper conductor wrapped 6～8 stratus master tape
Obtain insulated wire cores, refill inorganic fire-retarded layer at outer wall after described many insulated wire cores are stranded and form cable core, outside described cable core
The closely knit fire prevention mud layer that extrudes, then outreaches lock armouring copper sheath at fire prevention mud layer, is extruded with thermoplastics type's Halogen outside described copper sheath
Low-smoke flame-proof polyolefin outer jacket.
Insulated wire cores, this process medium cloud is formed by extruding polyolefin copolymer after wrapped 6～8 layers of synthetic mica tape overlap
Master tape can keep the limited activity of conductor copper wire as protective underlayer hot-face insulation while protecting, facilitates wiring to install.This
Bright middle polyolefin copolymer is with EVA or PE as matrix polymer, and doped with 5～20% nano-sized magnesium hydroxide and 2～12%
Nano hydrotalcite, wherein nano-sized magnesium hydroxide and brucite discharge at 200～800 DEG C structure who etc. fire retardant matter have excellent
Flame retardant effect, optimizes surface characteristic simultaneously and improves and inorganic fill flame-retardant layer after polyolefin insulation layer doped with hydrogen magnesium oxide
Surface contacts so that inorganic fire-retarded layer is more closely knit.
As preferably, the inorganic fire-retarded layer of described insulated wire cores outer wall is made up of following components: 20～80 parts of magnesium hydroxide,
5～10 parts of montmorillonites, 5～20 parts of glass fibre and the aluminium hydroxide of 10～20 parts.Insulation is avoided by content inorganic filling component
Core the dislocation in cable move, improve its fire resistance simultaneously further.Fire prevention mud layer is composed of the following components: 50
The chlorinated paraffin of part, the china clay in powder of 15 parts, the long glass fiber of 15 parts, the alumine of 10 parts.When cable breaking out of fire is burnt
Time, flame or smog escape through walls are avoided in fire-proof mud energy temperature distortion blocking cable through hole or drifting.
Further, between described copper protection set and outer jacket, it is additionally provided with Ceramic silicon rubber layer, simultaneously can be at outer jacket
Light communication cable and sensor are inside set, thus realize signal transmission and fault alarm function.Due to Ceramic silicon rubber layer
The shell forming some strength can be hardened after scene of fire is heated, play the effect of fire-retardant self-extinguishment, and extruding process
In to make the outer surface of ceramic rubber layer form spacing by extruding die head be the spiral yarn shaped groove of 0.5cm, by expanding
Large access area improves heat transfer efficiency and improves heat transfer flame retardant effect further.
