Abstract
The utility model relates to an optical cable is used on electric power circuit, including cable core, the insulating oversheath of cladding in the cable core periphery, the cable core include a plurality of optical fiber unit, every optical fiber unit include loose sleeve pipe, set up at the intraductal multi-beam optic fibre of loose sleeve, fill the fine cream between loose sleeve pipe and optic fibre, it still include with oversheath outside looks fixed connection's bearing body, the bearing body include glass fiber stick suspension wire, cladding in glass fiber stick suspension wire periphery and with oversheath looks body coupling's connecting sheath. Because the optical cable is provided with the bearing body, when erectting the installation, with the bearing body both ends snap-on of this optical cable on high-voltage transmission line pole, can accomplish and erect, the optical cable uses is non-metallic material moreover, has improved the insulating and anti-interference ability of optical cable, has reduced the dead weight of optical cable simultaneously, consequently, the installation is convenient and fast more, especially is fit for strideing across the aerial laying in environments such as rivers, valley, thunder and lightning concentrated region.
Description
Technical field
The utility model relates to a kind of optical cable, and this optical cable is mainly used on 220KV and the following power circuit.
Background technology
Use optical cable on the existing power circuit, comprise cable core, be coated on the insulation oversheath of cable core periphery, described cable core comprises that a plurality of fiber units are used for transmitting optical signal, this kind optical cable needs to fix steel strand wires between present electric pole when setting up, on steel strand wires, place some hooks then at a certain distance, thereby hang this optical cable, this kind optical cable has used metal original paper and common polythene material, be unfavorable for using on the ultra-high-tension power transmission line, and in practice of construction, can run into special construction environment, as cross over rivers, the mountain valley, in thunder and lightning concentrated area and the special pulling force environment, utilize existing optical cable to cause construction inconvenience, and the construction and installation process is loaded down with trivial details, consuming time longer.
Summary of the invention
The utility model purpose is to provide a kind of to be directly installed on the high voltage transmission line bar and to need not to adopt that thereby supplemental support is convenient to construct is used for optical cable on the power circuit in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: use optical cable on a kind of power circuit, comprise cable core, be coated on the insulation oversheath of described cable core periphery, described cable core comprises a plurality of fiber units, described each fiber unit comprises loose sleeve pipe, be arranged on the multiple beams of optical fiber in the described loose sleeve pipe, be filled in the fine cream between described loose sleeve pipe and the optical fiber, it also comprises the weight body that is fixedly connected with the described oversheath outside, and described weight body comprises the Fiber glass rod messenger wire, be coated on described Fiber glass rod messenger wire periphery and with the described oversheath connection sheath that connects of one mutually.
Described cable core also comprises and wraps that having of described a plurality of fiber units blocks water and the glass fibre layer that blocks water used of load.
Described cable core center also is provided with the glass bar strengthening core.
Also be provided with many between described oversheath and the glass fibre layer and tear rope.
Because technique scheme utilization, the utility model compared with prior art has following advantage: because optical cable is provided with weight body, when setting up installation, the weight body two ends of this optical cable directly are fixed on the high voltage transmission line bar, can finish and set up, and optical cable use be nonmetallic materials, the insulation and the interference free performance of optical cable have been improved, reduced the deadweight of optical cable simultaneously, therefore, install more convenient fast, especially be fit to cross over built on stilts the laying in the environment such as rivers, mountain valley, thunder and lightning concentrated area.
