Abstract
A directly buried photoelectric hybrid cable comprises a cable core and a sheath covering the cable core. The sheath comprises a polyester wrapping layer covering the periphery of the cable core, an inner protection layer and an outer protection layer from inside outwards. The cable core comprises at least one photoelectric hybrid unit for transmitting audio signals; each photoelectric hybrid unit comprises at least one optical fiber unit, a plurality of pairs of single wires twisted with each other and arranged around the optical fiber units, and a polyester wrapping belt covering the peripheries of the plurality of pairs of single wires; the optical fiber unit comprises at least one colored optical fiber, a loose sleeve covering the periphery of the colored optical fiber and fiber plaster filled between the loose sleeve and the colored optical fiber; and the single wire comprises a copper wire and an insulating layer covering the copper wire. The directly buried photoelectric hybrid cable is characterized in that the optical cable and the electric cable are mixed integrally; the laying of the optical cable and the electric cable can be completed through once construction and the pipeline resources and working hours are saved; and the single wires arranged to be twisted with each other effectively reduce interference, so that the transmission distance of electricity is increased.

Background technology
Traditional communication mode realizes with the local telephone communication cable transmission signal of telecommunication that all system of laying is mode built on stilts, pipeline mostly.Built on stilts mode is generally little logarithm, but causes signal interruption owing to be subject to extraneous mechanical scratch outside being exposed to.And pipe method is owing to the day conduit resource that is becoming tight and lay environment and be restricted.And the transmission of light signal need lay optical cable in the line.For avoiding the secondary construction, save conduit resource, need a kind of photoelectricity mixing cable product that can transmit photosignal simultaneously that can be used for direct-burried of exploitation.
The utility model content
The purpose of the utility model is to provide a kind of photoelectricity mixing cable that can be used for direct-burried.
For addressing the above problem; The technical scheme that the utility model adopted is: a kind of direct-burried photoelectricity mixing cable; Comprise cable core and be coated on the outer sheath of said cable core; Described sheath comprises polyester covering, sheath, the outer jacket that is coated on the cable core periphery from the inside to the outside; Described cable core comprises that at least one is used for the photoelectricity mixed cell of transmitting audio signal; Each described photoelectricity mixed cell comprise at least one fiber unit, many to the mutually stranded single line that is arranged on described fiber unit border, be wrapped in many polyester bands to described single line periphery, described fiber unit comprises at least one colored optical fiber, is coated on the loose sleeve pipe of described colored optical fiber periphery and is filled in the fine cream between loose sleeve pipe and the colored optical fiber that described single line comprises the insulating barrier that copper cash is outer with being coated on copper cash.
Further, described cable core comprises a plurality of photoelectricity mixed cells, the stranded setting of a plurality of described photoelectricity mixed cell phase spiral.
Described sheath comprises polyester covering, plastic-aluminum combined covering, sheath, wrinkle steel-tape armouring layer and outer jacket from the inside to the outside successively; Described plastic-aluminum combined covering can play moistureproof preferably shielding action, and described wrinkle steel-tape armouring layer has improved the lateral pressure resistant ability of photoelectricity mixing cable.
Further, the thickness of described plastic-aluminum combined covering is 0.2～0.3mm.
Further, the thickness of described wrinkle steel-tape armouring layer is 0.22～0.3mm.
Each fiber unit of optimizing comprises 2～24 colored optical fibers.
Described cable core also comprises at least one gasket for packing in the gap that is arranged on described polyester covering and photoelectricity mixed cell.
Further, have the effect that transmits electricity preferably for making photoelectricity mixing cable, described copper wire diameter is 0.32～0.6mm.
Owing to adopt such scheme, the utlity model has following advantage: the utility model mixes optical cable and is set to one with cable, only need once construct and just can accomplish laying of optical cable and cable, has saved conduit resource and man-hour; The single line of mutually stranded setting has effectively reduced interference, improves the transmission range of electricity.
