Abstract
Provided is a corrugated copper sheath inorganic mineral insulation flexible fireproof waterproof cable, belonging to the cable technical field and capable of meeting requirements of power supply length. The corrugated copper sheath inorganic mineral insulation flexible fireproof waterproof cable comprises a cable core which is wrapped by a cable core insulation sleeve; the structure main point lies in that an external surface of the insulation sleeve is wrapped by a corrugated copper sheath.
Description
Technical field
The utility model belongs to the cable technology field, relates in particular to a kind of embossing copper sheath inorganic mineral insulation fire resistant flexible water-proof cable.
Background technology
Along with Urbanization Process is constantly accelerated, population is more and more denser and concentrated, and high buildings and large mansions are not only much but also higher, and people more and more pay attention to building firesafety, technical performance level requirement to the building fireproof cable is more and more higher, and traditional fire-resisting cable can not adapt to Secretary.Traditional fire-resisting cable only has a technical performance index, namely is simple fire-resistant 750 ℃, keeps the integrality of electric wiring in 90 minutes, guarantees to send safely electricity; This is during with fire-fighting fire extinguishing, and thermal-flame, water drench and the actual conditions of mechanical shock differ greatly.After 2004, a plurality of cable producer has developed magnesium oxide insulated copper sheath cable in succession.Because the structure of magnesium oxide insulated copper sheath is limit, it is short that it manufactures length, many at use cable line center tap, bendability is poor, constructional difficulties.In addition, the easy moisture absorption of magnesium oxide, insulation resistance obviously descends after the moisture absorption, affects the cable serviceability.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of embossing copper sheath inorganic mineral insulation fire resistant flexible water-proof cable that can satisfy for the electrical length needs is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises cable core, is enclosed with the cable core insulating case on the cable core, and its structural feature insulating case outer surface is enclosed with the embossing copper sheath.
As a kind of preferred version, embossing copper sheath described in the utility model adopts the dephosphorization copper belt.
As a kind of preferred version, cable core described in the utility model is made of many copper conductors, is enclosed with the conductor insulation cover on the every copper conductor.
As a kind of preferred version, copper conductor described in the utility model is made of many stranded soft copper cores.
As a kind of preferred version, be filled with the inorganic glass fiber silk between the conductor insulation cover described in the utility model.
Secondly, cable core insulating case described in the utility model and conductor insulation cover all adopts inorganic synthetic mica tape.
In addition, inorganic synthetic mica tape described in the utility model is five layers, five layers of overlapping wrapped setting of inorganic synthetic mica tape.
The utility model beneficial effect.
The utility model embossing copper sheath can satisfy for the electrical length needs, no matter be single core or multicore cable, every continuous length can reach more than the 1000m; Shielding properties is superior, can not produce the information of signal, control cables transmission under the shielding of copper sheath and disturb; Security performance is good, and copper sheath is good conductor, is best PE line, has greatly improved ground protection sensitivity and reliability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Among the figure, 1 is that embossing copper sheath, 2 is that cable core insulating case, 3 is that conductor insulation cover, 4 is copper conductor.
Embodiment
As shown in the figure, the utility model comprises cable core, is enclosed with cable core insulating case 2 on the cable core, and the insulating case outer surface is enclosed with embossing copper sheath 1.Embossing copper sheath 1 can be by circular argon arc welding continuous rolling system.
Described embossing copper sheath 1 adopts the dephosphorization copper belt.Dephosphorization copper belt good waterproof performance, good airproof performance can be used as submerged cable and use.
Described cable core is made of many copper conductors 4, is enclosed with conductor insulation cover 3 on the every copper conductor 4.
Described copper conductor 4 is made of many stranded soft copper cores.The conductor that adopts many stranded soft copper cores to consist of has flexibility, and cable can coil on cable hank, and its bending radius≤20D(D is the outside diameter of cable), solved the poor problem of magnesium oxide insulated copper sheath cable bend.
Be filled with the inorganic glass fiber silk between the described conductor insulation cover 3.
Described cable core insulating case 2 and conductor insulation cover 3 all adopt inorganic synthetic mica tape.Inorganic synthetic mica tape has good insulating properties, thermal endurance and chemical resistance, heatproof: 1100 ℃, fusing point: 1375 ℃, cable can not burn in fire, can not melt in burning yet.
Described inorganic synthetic mica tape is five layers, five layers of overlapping wrapped setting of inorganic synthetic mica tape.
, Stability Analysis of Structures good through the fire-resistant burning of experiment confirm the utility model, cable seal be fastening is not afraid of mechanical shock.Its technical performance parameter: 1, fire-resistant merely: 950 ℃, 180min; 2, the fire-resistant water that adds drenches: 650 ℃, 15 minutes back are burnt limit water and were drenched 15 minutes; 3, fire-resistantly add mechanical shock: 950 ℃, vibrations in 15 minutes keep the electric wiring integrality 30 times.Therefore, the utility model can safety send electricity under fire condition, guarantee that fire-fighting equipment normally moves.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection range of the present utility model.
