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; and a sheathing layer can be covered outside the twisted optical cable. The cable can meet the need of transmitting electric energy and 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, 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 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, with trend go the same way 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 the winding bundle of light 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.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 one of the utility model embodiment.
Fig. 2 is two of the utility model embodiment.
Fig. 3 is three of the utility model embodiment.
Embodiment
As shown in Figure 1, the layer-twisted type optical cable is made of the metallic conduction core of electric energy transmitting and the optical fiber or the fiber bundle of transmitting optical signal, steel wire reinforcement 4 centerings, it is outer to be metallic conduction core 1, the optical fiber or the fiber bundle 2 of the nonmetal beam tube 3 of overcoat place between the internal layer conductor wire core 1, twist into the layer-twisted type optical cable.
As shown in Figure 2, reinforcement steel wire or vertical band 4 place the optical cable center, and it is outer to be double layer of metal conductor wire core 1, and the vertical therebetween fiber bundle 2 of putting two overcoat metal beam tubes 3 twists into optical cable, and outermost layer has restrictive coating 5.
As shown in Figure 3, the vertical fiber bundle 2 of putting the nonmetal beam tube 3 of overcoat on the center plastic skeleton 6, it is outer to be double layer of metal conductor wire core 1,5 one-tenth layer-twisted type optical cables of overcoat restrictive coating after the twisting.
Claims (3)
1. layer-twisted type optical cable, constitute by the metallic conduction core of electric energy transmitting and the optical fiber or the fiber bundle of transmitting optical signal, it is characterized in that said metallic conduction core (1) and said optical fiber or fiber bundle (2) twist into the layer-twisted type optical cable with center reinforcement (4), optical fiber or fiber bundle (2) can be indulged in the centering reinforcement (4), also can indulge to place between its outer each layer metallic conduction core (1).
2. layer-twisted type optical cable according to claim 1 is characterized in that outside said optical fiber or the fiber bundle (2) metal or nonmetal beam tube (3) being arranged, and reinforcement (1) can be plastic skeleton or steel wire or metal longitudinal binding band.
