Abstract
The utility model discloses a photoelectric composite cable which comprises a cable core and an outer sheath, wherein a stainless steel pipe is arranged in the center of the cable core, optical fiber is arranged in the stainless steel pipe, a shielding power wire and fillers are stranded around the stainless steel pipe outside the stainless steel pipe,. The utility model has the beneficial effects that: a PE (polyethylene) sheath of an optical cable in the photoelectric composite cable in the prior art is substituted by the stainless steel pipe so that the optical cable core wire has stronger lateral pressure resisting property and load-bearing capacity per se; an optical unit in the prior art is substituted by a stainless steel pipe optical unit, therefore, the diameter of the optical cable is greatly reduced under the condition of ensuring that the optical cable has stronger lateral pressure resisting property and load-bearing capacity per se; and as the stainless steel pipe optical unit is positioned in the center of the cable core, the shielding power wire is arranged around the stainless steel pipe optical unit, and the size of the power wire can be also appropriately increased, therefore, the utility model is suitable for long-distance and large-load circuits.
Description
Technical field
The utility model relate to a kind of can transmitting optical signal again can transmission of electric signals optoelectronic composite cable.
Background technology
In a lot of occasions, often need the transmitting optical signal and the signal of telecommunication simultaneously, normally lay respectively as the optical cable of optical signal transmission with as the cable of signal of telecommunication transmission, this not only brings difficulty to construction, has also increased construction and use cost.Be meeting the market requirement, people develop a kind of optoelectronic composite cable, and the cable that this optoelectronic composite cable will transmit several signals combines, and light unit, shielded power supply line are generally arranged in cable core, and the telephone wire in addition that has etc. transmits the holding wire of the signal of telecommunication.Authorize on May 21st, 2008 bulletin, China Patent No. is that 20072004117.6 utility model patent " novel photoelectric composite rope " has just been announced a kind of like this optoelectronic composite cable.This optoelectronic composite cable comprises the cable core with central reinforce member, the same protective layers such as waterstop, oversheath that are provided with ordinary optical cable or cable in the cable core outside.In cable core, be provided with optical cable, telephone wire, shielded power supply line etc. around the cable core central reinforce member.The unit that such optoelectronic composite cable will transmit several signals combines, and has saved pipeline space greatly, has reduced cost, has made things convenient for installation, is fit to laying in internal home network wiring and the urban building building.But this kind optoelectronic composite cable is not suitable for long distance, heavy load circuit.
Summary of the invention
In order to overcome the above-mentioned deficiency of optoelectronic composite cable of the prior art, the utility model provides a kind of optoelectronic composite cable that is suitable for long distance, the use of heavy load circuit.
The utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of optoelectronic composite cable, comprise cable core and oversheath, at the center of described cable core is a stainless steel tube, in described stainless steel tube, be provided with optical fiber, outside described stainless steel tube, shielded power supply line and filler are twisted into cable core around described stainless steel tube.
The beneficial effects of the utility model are, utilize stainless steel tube optical unit to replace smooth unit of the prior art, when guaranteeing that optical cable itself has stronger lateral pressure resistant performance and weight capacity, reduce the diameter of optical cable greatly.Because stainless steel tube optical unit is positioned at the cable core center, around stainless steel tube optical unit, the shielded power supply line is set, then the power line size also can suitably increase, and the circuit that is suitable for long distance, heavy load uses.
Further, outside stainless steel tube, apply layer of polyethylene (PE) bed course, make stainless steel tube have the good insulation performance performance outward like this.Optical transmission and electrical transmission signal do not disturb mutually.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model embodiment.
Among the figure: 1, optical fiber, 2, stainless steel tube, 3, gasket for packing, 4, the shielded power supply line, 5, oversheath, 6, the sign vitta.
Specific embodiment
Fig. 1 is the sectional view of embodiment of the present utility model, as shown in the figure, the optoelectronic composite cable outside is an oversheath 5, here the oversheath 5 of optoelectronic composite cable is to use polyethylene (PE) material to extrude to form, for the convenience on discerning, when extruding polyethylene (PE) oversheath 5, can extrude the colored marking vitta 6 that is used to discern simultaneously.Be cable core in oversheath 5, the center of cable core is a stainless steel tube 2, has applied the layer of polyethylene bed course outside the stainless steel tube 2, is provided with optical fiber 1 in stainless steel tube 2, in order further to protect optical fiber, has also filled fine ointment around optical fiber.Shielded power supply line 4 and the gasket for packing 3 that may need are twisted into compact circular cable core around stainless steel tube.For remote power-feeding, present embodiment is provided with 4 shielded power supply lines.Be used to transmit the three-phase four-wire system electricity consumption.
Present embodiment has been inherited the advantage of electric power optical cable, central reinforce member adopts the stainless steel tube 2 through the PE coating that comprises optical fiber 1, stainless steel tube 2 not only plays the center booster action, and transmitting optical signal, in addition, when guaranteeing the anti-lightning performance of optical cable, make optoelectronic composite cable possess good lateral pressure resistant performance again.The gasket for packing 3 of shielded power supply line 4 and insulation is stranded in simultaneously and constitutes circular cable core on the stainless steel tube 2, but but both transmitting optical signal also transmission of electric signals simultaneously of the circular cable core that is twisted into, the optical cable outermost layer is provided with the colored marking vitta 6 of the quick identification of being convenient to optical cable and polyethylene (PE) sheath 5 with good anti-ultraviolet radiation performance.
Low, the technological performance of this optoelectronic composite cable cost of investment can provide faster speed and higher reliability on data and transmission of video images.This kind optoelectronic composite cable also must promote the faster and better development of China's Telecommunication's cause growing the space that has a wide range of applications on distance, the heavy load circuit.
The advantage of present embodiment is:
● optical fiber and power line are compounded in the same optical cable.
● optical cable and power line are once constructed, and shorten the engineering time, save operating expenses.
● the center stainless steel tube applies through PE, has good insulation performance, and optical transmission and electrical transmission signal do not disturb mutually.
● the center stainless steel tube has good humidity resistance.
● the center stainless steel tube has good lateral pressure resistant and tensile property.
● the power line size is big, is suitable for long distance, heavy load circuit.
● extrude P E oversheath and can extrude colored vitta simultaneously, so that the quick identification of optical cable.Polyethylene (PE) sheath has good anti-ultraviolet radiation performance.
