Description
Technical field
This utility model relates to electric wire field, particularly relates to intelligent building minerals insulated copper sheath soft
Property fireproof cable.
Background technology
Along with high-rise, large-scale public place sharply increase, the security requirement to building is more and more higher.
The building building green, safety and environmental protection is that 21 century basic architecture is seen, and how to ensure circuit peace in building
Row for the national games, the most once occurs that concrete on fire guarantees that emergency lighting, automatic alarm and disaster relief system can be the rapidest
Normal work, keeps power supply safety under state of catching fire, and fireproof cable is must obligato product in building.Energy
The fire prevention power technology one meeting fire-fighting requirements is MI type mineral insulated cable (i.e. BTTZ type mineral insulation
Cable), this cable is due to the easy moisture absorption of magnesium oxide insulated, and cable is the most moistureproof requires height, especially joint
Locating once metallic sheath damage, meet water, cable will lose function of supplying power；Secondly this cable manufacturing process also limit
Drum length of cable, cable length is shorter, causes joint to increase；Cable is harder again, the most flexible, installs
Construction inconvenience, along with cable material and the progress of processing technique, market also occurs in that the numerous flexibility of kind is prevented
Thermoelectricity cable, such flexible fire-proof cable can solve MI type mineral insulated cable relevant issues, in the market
Flexible fire-proof cable have with inorganic band insulation add argon arc welding copper pipe structure, have inorganic band insulation aluminum protection of pipe
Structure, ceramic silicone insulation chain Sheathed metal shielding layer structure etc., although these cables can meet standard gauge
Fixed fire resistance test requirements document, but the most all there is following six problem in these cables, causes the wasting of resources
Greatly, cost is high；(1) electric property is unstable, it is high to puncture rate；(2) fire condition lower conductor temperature is high, line
Road end pressure drop is big；(3) easy to crack during argon-arc welding seam bending, the most at high temperature easily blow during burning；
(4) when aluminum protection structure is at high temperature burnt, aluminium lamination fusing, does not has protective effect；(5) chain armored type
Waterproof effect is poor, it is impossible to water spray disaster relief requirement when satisfied reality is caught fire；(6) no matter use aluminum to protect or aluminum closes
Gold sheath, its earth resistance is big, and ground connection performance is unreliable.Therefore, above cable still has is worth the place of improvement.
Utility model content
It is flexible that the purpose of this utility model is to provide a kind of high security intelligent building mineral insulation copper sheath
Fireproof cable.
The technical scheme realizing this utility model purpose is: a kind of intelligent building minerals insulated copper sheath is soft
Property fireproof cable, including at least insulated wire cores from the inside to the outside, heat insulation filling sheath and outer jacket；Institute
State insulated wire cores and be followed successively by conductor thread core, refractory insulating layer and copper protective layer from the inside to the outside；Described copper protective layer is
Airtight seamless copper or copper alloy tube；Described heat insulation filling sheath is that inorganic mineral material is further around bag mineral
Fire insulation band, or extrude mineral-filled interior protective material.
Described refractory insulating layer is wrapped mineral insulation composite band or is the mineral insulation band extruded, resistance to
The thickness of fire insulating barrier is 0.5-3.0mm.
Described conductor thread core is single annealed copper single line or many annealed copper single lines are stranded forms, described middle annealing
Copper single line is round wires or molded line；In described many annealed copper single lines, each single line area is identical or differs.
The thickness of described copper protective layer is 0.15-1.5mm.
The copper of copper protective layer or the appearance of copper alloy tube are threaded, and the spacing of screw thread is 3-35mm, screw thread
The degree of depth is 0.5-4.0mm.
The thickness of described heat insulation filling sheath is 0.5-5.0mm.
Described refractory insulating layer uses refractory insulating layer band wrapped, or uses synthetic mineral Insulation Material to extrude.
Described outer jacket is low-smoke halogen-free polyolefin material.
Have employed technique scheme, this utility model has following beneficial effect: (1) is of the present utility model
Outside each core, extrude seamless copper protection pipe respectively, on the one hand make the refractory insulating layer within copper protective layer tighter
Close, improve insulation effect, on the other hand make insulating barrier better tightness, will not ftracture, fire prevention can be played anti-
Water effect.Use copper protective layer can play the effect of good ground connection, compared with remaining flexible fire-proof cable simultaneously
A core can be saved, not only reduce cable cost, and make cable have stronger proof voltage impact, to setting
For playing a good protection, on the other hand copper pipe improves the pliability of cable after embossing so that cable
It is easier to lay and install.
(2) cable of the present utility model is owing to filling and being coated with mineral between cable core and outside cable core
Matter class refractory insulating layer, on the one hand this mineral layer discharges water of crystallization, on the other hand can produce when high-temp combustion
Crust protection, can play well cooling and thermal insulation protection effect, greatly reduce at the state lower conductor that catches fire
Temperature, reduction line drop.
(3) in cable of the present utility model, all material all will not produce flue gas, has preferable environmental-protecting performance.
(4) this utility model not only solve conventional mineral insulated cable processing difficulties, produce length short,
Bending property is poor, also solve that all kinds of flexible fire-proof cable fire resistance is unstable, insulation breakdown rate is high, simultaneously
The problems such as fire condition lower end pressure drop is big, external diameter big, ground connection performance not guarantee, substantially increase cable fire
Under the conditions of the security and stability that runs, not only under the state of catching fire can normal power supply, and meet fire control and disaster rescue
Shockproof, waterproof requirement, the most also ensures that fire-fighting equipment normally starts.
