Description
Technical field
The utility model relates to a kind of optical fiber composite cable, especially a kind of fire-type optical fiber composite cable.
Background technique
Existing power cable does not have fire prevention and transmission semiotic function, for requiring fire prevention, high temperature resistant simultaneously, and can pass
For the place of power of transmitting electricity and photosignal function, fire proof power cable and signal optical cable must be just laid simultaneously, in this way to one
For a little large-diameter buildings, subway, rail traffic, densely populated place, cable and fiber cable laying region are increased, is increased
Human and material resources cause the waste of substantial contribution.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of fire-type optical fiber composite cables.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
A kind of fire-type optical fiber composite cable, it is characterised in that: comprising several fireproof cable cores, several fiber optic bundles,
Wrapping layer, copper sheath and oversheath, several fireproof cable cores and several fiber optic bundles are twisted bunchy, and wrapping layer is arranged several
On the outside of root fireproof cable core and several fiber optic bundles, copper sheath is arranged on the outside of wrapping layer, and oversheath is arranged on the outside of copper sheath,
Every fireproof cable core includes conductor and the fireprotection layer and inorganic insulation layer that are successively set on the outside of conductor from inside to outside.
Further, several fireproof cable cores are mutually twisted, and several fiber optic bundles twist together with fireproof cable core
Merge and fiber optic bundle is arranged in fireproof cable core gap.
Further, the fireprotection layer forms for resistance to 1200 DEG C of synthetic mica is wrapped.
Further, gap is filled using fire-proof mud between several fireproof cable cores, several fiber optic bundles.
Further, the wrapping layer uses low-smoke bittern-free highly fire-proof band.
Further, buffer water-blocking band is provided between the wrapping layer and copper sheath, buffer water-blocking band is around wrapped
Layer outside.
Further, the copper sheath is wrinkle copper sheath.
Further, the oversheath uses low-smoke halogen-free polyolefin oversheath.
The utility model compared with prior art, has the following advantages that and effect:
1, fiber optic bundle is integrated into cable and forms photoelectric compound cable, thus had both power transmission and signal transmission
Function, laying is more convenient, has saved manpower and material resources；
2, it is filled using fire clay, compared with common gasket for packing, filling is got up more convenient, while fire clay energy
Enough protections that comprehensive surrounding is formed to internal cable core and fiber optic bundle, flameproof effect are better；
3, using wrinkle copper sheath, while effectively shielding external interference, more soft pliable is bent, applies convenient for scene
If.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of fire-type optical fiber composite cable of the utility model.
Specific embodiment
Below by embodiment, the present invention is described in further detail, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
As shown in Figure 1, a kind of fire-type optical fiber composite cable of the utility model, if comprising several fireproof cable cores,
Dry root fiber optic bundle 1, wrapping layer 2, copper sheath 3 and oversheath 4, several fireproof cable cores and several fiber optic bundles 1 are twisted bunchy,
The setting of wrapping layer 2 is in several fireproof cable cores and several 1 outsides of fiber optic bundle, and the setting of copper sheath 3 is in 2 outside of wrapping layer, outside
The setting of sheath 4 includes conductor 5 and is successively set on the outside of conductor 5 from inside to outside in 3 outside of copper sheath, every fireproof cable core
Fireprotection layer 6 and inorganic insulation layer 7.Fiber optic bundle is integrated into cable and forms photoelectric compound cable, to have both electric power biography
The function of defeated and signal transmission, laying is more convenient, has saved manpower and material resources.
Several fireproof cable cores are mutually twisted, and several fiber optic bundles 1 are twisted together with fireproof cable core and fiber optic bundle
It is arranged in fireproof cable core gap.Fireprotection layer 6, which is that resistance to 1200 DEG C of synthetic mica is wrapped, to be formed.
Gap is filled using fire-proof mud 8 between several fireproof cable cores, several fiber optic bundles 1.It is carried out using fire clay
Filling, compared with common gasket for packing, filling is got up more convenient, while fire clay can be to internal cable core and fiber optic bundle
The protection of comprehensive surrounding is formed, flameproof effect is better.
Wrapping layer 2 uses low-smoke bittern-free highly fire-proof band.Buffer water-blocking band 9 is provided between wrapping layer 2 and copper sheath 3,
Buffer water-blocking band 9 is around 2 outside of wrapping layer.Copper sheath 3 is wrinkle copper sheath.It is outer in effective shielding using wrinkle copper sheath
While boundary interferes, more soft pliable is bent, convenient for scene laying.Oversheath 4 uses low-smoke halogen-free polyolefin oversheath.
For a kind of fire-type optical fiber composite cable of the utility model when manufacturing, every conductor uses resistance to 1200
DEG C synthetic mica it is wrapped, squeezed out using inorganic insulation, fiber optic bundle and power cable core are together using fire prevention in cabling process
Mud filling, is tightened, wrapped buffer water-blocking band prevents moisture from entering influence fire resistance, using wrinkle with low-smoke bittern-free highly fire-proof band
Line copper sheath keeps cable more soft, convenient for laying, increases fire protecting performance, finally uses low-smoke halogen-free polyolefin sheathing packet
It wraps up in, making cable further has more superior fire protecting performance, while can transmit electric power and communication.
