Abstract
The utility model relates to an optical cable which can be used to transmit both electric energy and optical signals. The optical cable is characterized in that a twisted optical cable is twisted by metal or a nonmetal reinforcing component arranged in the center and the optical fiber beam of an external band beam tube and a metal conductive wire core, the surface of the optical cables is provided with a marker line which is significantly different from other cables. The cable can meet the need of transmitting the electric energy and the optical signals by one cable; the cable is safe and reliable and is easy to be laid.
Description
Technical field
The utility model relates to light, electrical transmission media, promptly with the optical cable of cable transmitting optical signal and the cable of electric energy transmitting.
Background technology
In electric power system, transmission or distribution high voltage, high-power electric energy will use the power cable of different electric pressures.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 power system; Insulating barrier and sheath are arranged, and outer jacket, can bear active forces such as mechanical external force or pulling force, safety is difficult for advantages such as impaired, but only can electric energy transmitting.And as the optical cable of optical signal transmission medium, for guarantee under various conditions with various environment in long its use, must make baroque optical cable.In society now, usually need simultaneously, go the same way, with moving towards electric energy transmitting and light signal, satisfying the needs of power and message 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 utility model 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.The utility model twists into the layer-twisted type optical cable by the optical fiber of the metallic conduction core of electric energy transmitting and transmitting optical signal or fiber bundle and center reinforcement, optical fiber or fiber bundle can be indulged in the centering reinforcement, also can indulge to place it outer arbitrarily between the layer of metal conductor wire core.Optical fiber or fiber bundle are outer can metal or nonmetal beam tube, and reinforcement can be plastic skeleton or steel wire or metal longitudinal binding band.Optical cable can have restrictive coating, and there are the markings that obviously are different from other cable on the optical cable surface.The concentric layering integument strand of the utility model optical cable, simple in structure, intensity is good, easily lays, and can satisfy with the instructions for use of moving towards cabling or optical cable.
Description of drawings
Fig. 1 is the cross sectional representation of one of the utility model embodiment.
Fig. 2 is two the cross sectional representation of the utility model embodiment.
Embodiment
As shown in Figure 1, the layer-twisted type optical cable is made of the metallic conduction core 2 of electric energy transmitting and the optical fiber or the fiber bundle 5 of transmitting optical signal.Steel wire reinforcement 3 centerings, it is outer to be metallic conduction core 2, any one deck of optical cable or which floor optical fiber of overcoat metal or nonmetal beam tube 4 or fiber bundle 5 place, and twist into the layer-twisted type optical cable.Optical cable can have restrictive coating 1, and there are the markings that obviously are different from other cable on the optical cable surface.
As shown in Figure 2, the layer-twisted type optical cable is made of the metallic conduction core 2 of electric energy transmitting and the optical fiber or the fiber bundle 5 of transmitting optical signal.Steel wire reinforcement 3 centerings, it is outer to be metallic conduction core 2, any one deck of optical cable or which floor optical fiber of overcoat metal or nonmetal beam tube 4 or fiber bundle 5 place, and twist into the layer-twisted type optical cable.There are the markings that obviously are different from other cable on the optical cable surface.
