Specific embodiment
The present invention will be further described with reference to embodiments:
Embodiment 1
Fig. 1 is that a kind of double-deck crosslinked with silicane copper strips of the utility model always shields steel wire woven armored converter cable (armouring
Type) schematic cross-section.
Present embodiment discloses a kind of double-deck crosslinked with silicane copper strips always to shield steel wire woven armored converter cable (armouring
Type), as shown in Figure 1, the first anaerobic copper conductor 1 is phase conductor, the second anaerobic copper conductor 13 is gnd conductor, first nothing
Oxygen copper conductor 1 and the second anaerobic copper conductor 13 are the conductor that solid or stranded copper wire is twisted, and copper wire is greater than for purity
99.98% red copper.
Successively longitudinal wrap ceramic fire resisting composite band 2 outside first anaerobic copper conductor 1, extrudes 90 DEG C of organosilane crosslinked polyethylene insulations
3 and 90 DEG C of silane crosslinked halogen-free low-smoke flame-proof polyolefin insulation 4.Successively the fire resisting of longitudinal wrap ceramic is multiple outside second anaerobic copper conductor 13
Crossed belt 2 extrudes 90 DEG C of organosilane crosslinked polyethylene insulation 3 and 90 DEG C silane crosslinked halogen-free low-smoke flame-proof polyolefin insulation 4.Wherein
One anaerobic copper conductor 1 and the second anaerobic copper conductor 13 are the conductor that stranded copper wire is twisted, and conductivity is high, are transmitted as electric current
Carrier, the ceramic fire resisting composite band 2 of the outer longitudinal wrap of the conductor, as cable fire layer, longitudinal wrap ceramic fire resisting composite band
Technique improves production efficiency simultaneously instead of the technique of the wrapped mica tape of traditional fire-resistant wires, overcomes in flame calcination feelings
Under condition, since Mica tape is not close, in the case of by flame calcination, mica powder falls off, and then the shortcomings that influence fire resistance,
Meanwhile ceramic fire resisting composite band has under conventional environment, moisture-sensitive, can not in very short time in flame calcination
Calcination forms dense protective layer, cooling isolation fire source, so that wire body remains to stablize the excellent spy of continued power at ceramic shell
Property.
90 DEG C of organosilane crosslinked polyethylene insulations, 3,90 DEG C of silane crosslinked halogen-free low-smoke flame-proof polyolefin insulation 4 are collectively as electricity
Gas protects cross linked insulation layer, and process thickness is than being about 3:7, and to guarantee and enhance the integral insulation performance of cable, and the two is same
When by warm water environment realization be crosslinked, the design of such process structure, using material property advantage, avoid because merely be crosslinked gather
Ethylene flame-resistant insulation is poor, the defect that simple low smoke, zero halogen insulated with material dampness insulation resistance is decreased obviously, good comprehensive material
Advantage is expected, so that cable overall performance is obviously improved, it is ensured that electric property, the resistance to ag(e)ing of cable are excellent, so that cable
The service life is longer, and low smoke, zero halogen is environmentally protective.Three phase line insulated wire cores with dielectric layers insulate with three ground wires
Core twisted synthesizing cable, flame resistant filler rope 5 is filled at stranding gap, and cable core outer layer uses the first low-smoke non-halogen flame-retardant band
6 (four layers of low-smoke non-halogen flame-retardant glass fiber tape overlapping are wrapped), as the first cooling refuge floor, wrapped Duplication is about bandwidth
40%~50%, wrapped flat and smooth no protrusion.
Outside first cooling refuge floor, the first low smoke halogen-free flame-retardant polyolefin sheath 7 is successively extruded, wrapped copper strips is overlapped
Total shielded layer 8, wrapped the second low-smoke non-halogen flame-retardant band 9 (the second cooling refuge floor, two layers of low-smoke non-halogen flame-retardant glass fibre
Band), the second low-smoke non-halogen flame-retardant separation layer 10 (the second cooling refuge floor, low smoke halogen-free flame-retardant polyolefin) extruded, steel wire is compiled
Armor 11 is knitted, low-smoke and halogen-free flame retardant polyolefin jacket 12 (third low-smoke and halogen-free flame retardant polyolefin jacket) is extruded.
Embodiment 2
Fig. 2 is that a kind of double-deck crosslinked with silicane copper strips of the utility model always shields steel wire woven armored converter cable (non-armour
Dress) schematic cross-section.
The present embodiment is substantially the same with embodiment 1, unlike, in the present embodiment process structure, do not include the second low cigarette
Halogen-free flameproof separation layer 10 and steel wire woven armored 11, but after the completion of the second low-smoke non-halogen flame-retardant 9 technique of band, directly extrude
Low-smoke and halogen-free flame retardant polyolefin jacket 12 (oversheath), as the fire-retardant outer jacket of cable, preferably, in such cases low
The oxygen index (OI) of cigarette halogen-free anti-flaming polyolefin protective cover material should be greater than 34, to guarantee the flame retardant property of cable entirety.
The utility model is not limited to the above embodiment a kind of recorded novel double-deck crosslinked with silicane copper strips and always shields steel wire
Armouring converter cable is woven, wherein the change of oxygen-free copper conductor structure, the change of each thickness degree are in the guarantor of the utility model
Within the scope of shield.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
