Abstract
The present invented photoelectricity cable is also known as electric light cable, which is a transmission medium-wire cable capable of same way transmitting electric energy and electrical signal. The metallic conduction wire core of Said wire cable is parallel with optical fiber of cable, optical fiber longitudinal located inner or outer of reinforced member, metallic conduction wire core and optical fiber covered with insulation protection layer and integrated by external sheath layer, photoelectricity cable cross section presenting dumb-bell shape. Fiber-optic reinforced member can be plastics frame or steel wire and metal longitudinal binding band. Photoelectricity cable can meet the requirement of less than 10 kw electric energy transference and optical fiber network communication.
Description
Technical field
The present invention relates to light, electrical transmission media, i.e. the cable of the optical cable of transmitting optical signal and electric energy transmitting.
Background technology
In electric system, transmit or distribute high-power (10KV or 35KV following) electric energy will use the power cable of different voltage levels.Power cable is compared with aerial bare line, have be subjected to extraneous climatic environment disturb little, power supply reliability is high; Electric capacity is bigger, helps improving the power factor of electric system; Insulation course and sheath are arranged, and outer jacket, can bear mechanical external force or pulling force is made power, safety is difficult for advantages such as impaired, but only can electric energy transmitting.And,, must make baroque optical cable in order to guarantee under various laid condition and various environment are medium-term and long-term uses as the optical fiber of optical signal transmission medium.In society now, usually need simultaneously, with trend go the same way electric energy transmitting and light signal, satisfying the needs of power and information transmission and measurement, thereby need power cable laying and optical cable respectively, this has just increased engineering difficulty and construction investment greatly.
Summary of the invention
The present invention be exactly to provide a kind of can electric energy transmitting again can be with the optical cable or the electrical-optical cable that move towards transmitting optical signal.Optical cable of the present invention partly is made of the cable part of electric energy transmitting and the optical cable of transmitting optical signal.Cable metallic conduction core partly is parallel with optical cable optical fiber partly.The vertical reinforcement that places of optical fiber is interior or outer.Metallic conduction core and optical fiber clad insulating protective layer outward separately, and the restrictive coating outside it is connected as a single entity.The optical cable xsect is dumb-bell shape.The reinforcement of optical fiber can be plastic skeleton or steel wire and metal longitudinal binding band.
Optical cable is with one or more optical fiber, or fibre bundle is made.The transmission quality that its structure directly influences light signal is the cable laying operation requirement, must meet the optics of optical fiber, the requirement that machinery is environmental characteristics.Existing optical cable generally is made up of cable core, sheath and strengthening core.Therefore, need have higher structural design equally, to guarantee transmission requirement and quality as the component part of optical cable.But can utilize cable architectural characteristic partly, both are complemented each other.The cable section of optical cable of the present invention can be guaranteed normal electrical transmission, can bear optical cable and partly install and use suffered external force for optical cable provides mechanical support again, overcomes the fragility of optical fiber and the characteristic that microbending loss increases, and guarantees the stability and the reliability of optical fiber.And cable becomes the structure of dumb-bell shape can make cable and optical cable partly be easy to be divided into two in the optical cable with optical cable parallel longitudinal, xsect, and the relatively independent structure of each self-sustaining, the introducing when being convenient to install, draws and joint.

Embodiment
Optical cable of the present invention has numerous embodiments, shown in the accompanying drawing only for wherein several.
As shown in drawings, optical cable of the present invention is made of the cable of electric energy transmitting and the optical cable of transmitting optical signal.The metallic conduction core 2 of cable is parallel with the optical fiber 5 of optical cable, and optical fiber 5 is vertical to be placed in the reinforcement or outer, metallic conduction core 2 and optical fiber 5 are outer clads insulating protective layer separately, is connected as a single entity through its outer jacket 3, and the optical cable xsect is dumb-bell shape.The reinforcement of optical fiber 5 can be plastic skeleton 7 or steel wire 6 and metal longitudinal binding band 4.Plastic skeleton among the figure has the center to increase the positive and negative spirality of spirality, dispersion strengthens multiple structures such as elementary cell shape.The plastic skeleton 7 of Fig. 2 is a helical structure, and its material is generally low density polyethylene.7 pairs of optical fiber 5 of plastic skeleton have the excellent protection performance, and side pressure strength is good, and to construction, especially pipeline lays favourable.The optical fiber of primary coating can directly be positioned in the internal frame groove of skeleton 7, saves the secondary coated process of loose sleeve pipe, helps optical fiber and connects.The optical fiber duct of skeleton 7 can be selected geometric configuration and suitable joint tool in the optical fiber manufacture process, make excess fiber length be fit to the needs of fiber stress and hot expansibility.Optical fiber 5 among Fig. 3 places highstrenghtpiston's optical fiber bundle tubes 11, disperses reinforcement steel wire 6 to be configured in around the sleeve pipe, and intensity is good, and is withstand voltage especially, can prevent the influence of rugged surroundings and the barbarous operation that may occur, and can improve the stability and the reliability of Network Transmission.And this beam tube type structure, owing to be directly the curing optical fiber of primary coating to be positioned in the beam tube, so the fiber capacity of optical cable is flexible, four-core, four, 50 even eight, 90 cores at most at least.External sheath layer 3 can adopt Polyvinylchloride, tygon or aluminum-polyethylene, or the LIP oversheath that aluminium strip and tygon are formed adds wire armoring etc., makes outer jacket have withstand voltage, moistureproof, good temp characteristic, in light weight, chemically-resistant etch and characteristics such as fire-retardant.But optical cable pipeline laying of the present invention, but also direct-burried, built on stilts reaching are laid under water.
