The copper leads and the optical cable are integrated, so that the flame-retardant photoelectric composite low-voltage cable has the functions of low-voltage power transmission and optical signal transmission, and is convenient to apply; anti-jamming isolation of signals is achieved through the isolation sleeve; and the tensile property of the flame-retardant photoelectric composite low-voltage cable is enhanced through the steel tape armoring sheath.
Description
Technical field
The utility model relates to a kind of low-voltage cable, relates in particular to a kind of compound low-voltage cable of flame retardant type photoelectricity that has low-voltage power transmission and optical signal transmission function concurrently.
Background technology
Along with the high speed development of power industry and electron trade, also more and more to the application of power cable and optical cable.At present there have been a lot of occasions need use the occasion of low tension and optical signal transmission simultaneously, existing method is with low tension and separately transmission of light signal, adopt low-voltage cable transmission low tension, adopt the optical cable transmitting optical signal, in long distance, jumbo application, have only this mode could satisfy transmission demand, but in the transmission of short distance, low capacity is used, this mode makes its application more loaded down with trivial details, and circuit is many, easy confusion, causes and uses inconvenience.
The utility model content
The purpose of this utility model provides a kind of compound low-voltage cable of flame retardant type photoelectricity that has low-voltage power transmission and optical signal transmission function concurrently with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The compound low-voltage cable of flame retardant type photoelectricity described in the utility model comprises many copper conductors, described many copper conductors are made up of bare copper wire and the PVC insulating barrier that is coated on described bare copper wire outside, and the outside of described many copper conductors is coated with low-smoke non-halogen flame-retardant thermosetting oversheath; The compound low-voltage cable of described flame retardant type photoelectricity also comprises the optical cable that an insulating barrier that is coated by multifiber and described multifiber outside is formed, described optical cable places in the many spaces between the described copper conductor, is disposed with polyester belt, separation sleeve and steel-tape armouring sheath from inside to outside between the outside of described many copper conductors and described optical cable and the described low-smoke non-halogen flame-retardant thermosetting oversheath.
Particularly, described separation sleeve is the polyethylene separation sleeve.
Further, be filled with fire proofing between the described many copper conductors and in the space between described copper conductor and the described optical cable.As preferably, described fire proofing is an aluminium hydroxide.
