Abstract
The invention discloses an optical-fiber composite type mining cable. The optical-fiber composite type mining cable comprises a cable core, wherein semi-conductive water resisting yarns are filled into gaps in the cable core; the cable core is externally wrapped with a semi-conductive water resisting belt, and the outermost layer of the cable core is extruded by an outer sheath; and the cable core is formed by twisting a plurality of power cable cores, a centralized monitoring cable core and an optical-fiber unit. The optical-fiber composite type mining cable disclosed by the invention not only integrates power transmission and signal transmission, but also has the inherent properties of the domestic mining cable, has the properties such as fire resistance, corrosion resistance, interference resistance and high-flame-retardance monitoring and also has a waterproof function.
Description
Technical field
The present invention relates to the power cable field, especially a kind of colliery down-hole survival capsule electric power, signal transmission fiber composite cable of being applicable to.
Background technology
At present; The use of colliery down-hole survival capsule is very universal, has obtained too using widely for survival capsule provides the mining cable of power supply, signal and telecommunication cable, and mining cable generally is divided into mining power cable, rubber sheathed flexible cable for mine and communication cable for mine; The general selective light fiber communication of telecommunication cable; This communications distance, loss is low, and transmission capacity is big.Mining cable is that survival capsule is done power supply connection use, and telecommunication cable then provides the signal transmission for the communication apparatus in the survival capsule.Become the first-selection of intelligent grid user incoming end along with fiber composite power cable; Its utilization has obtained the approval of national grid, yet, the domestic research that does not also have Optical Fiber Composite type mining cable this respect; On this basis; We can the reference fiber composite power cable method, optical fiber effectively is compound in the mining cable, down-hole survival capsule obtains generally being widely used in the colliery to make it.
And the deficiency that prior art exists: at present; To survival capsule under the coal mine mining cable of power supply and signal and telecommunication cable being provided generally all is that power supply and signal source separately are provided; Use has not only increased the use cost of cable like this, and connection has increased the inconvenience that cable is installed first like this, has second increased the unsafe factor in the cable use; In case three cables break down, will bring difficulty to the cable maintenance.
Summary of the invention
The technical problem that the present invention will solve provides a kind ofly can carry power supply, and the Optical Fiber Composite type mining cable of signal source can be provided again simultaneously.
A kind of Optical Fiber Composite type mining cable of the present invention comprises cable core, and the space in cable core is filled the semiconductive water blocking yarn and filled, and wrapped semiconductive waterstop and outermost layer extrude oversheath outside cable core; Said cable core is by several power cores, a concentrated supervision core and stranded the forming of fiber unit.
Said power core is to be combined by power line core conductor and outer conductor screen, insulation, insulation shielding, the metal knitted shielding that coats successively of power line core conductor.
Said concentrated supervision core is to be extruded outward by the concentration line core conductor to concentrate the pilot wire core insulation, and the braided metal braid shielded forms outside concentrated pilot wire core insulation.
Beneficial effect of the present invention is:
The present invention mainly does colliery down-hole survival capsule power supply connection and provides signal source to use; The transmission of current collection power and signal transmission and one; Make originally synthetic one of two cables, provide cost savings, but also have waterproof, anticorrosion, anti-tampering, high flame retardant and monitoring cable operation function.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of Optical Fiber Composite low-voltage cable of the present invention comprises cable core, and the space in cable core is filled the semiconductive water blocking yarn and filled 10, and wrapped semiconductive waterstop 11 and outermost layer extrude oversheath 12 outside cable core; Said cable core is by several power cores, a concentrated supervision core and fiber unit 1 stranded forming.
Above-mentioned described power core is to be combined by the conductor screens 3 that coat successively outside power line core conductor 2 and the power line core conductor 2, insulation 4, insulation shielding 5, metal knitted shielding 6; Described concentrated supervision core is to concentrate pilot wire core insulation 8 by concentration line core conductor 7 outer extruding, and braided metal braid shielded 9 forms outside concentrated pilot wire core insulation 8.
The invention provides a kind of version and implementation method of Optical Fiber Composite type mining cable; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
