Optical fiber composite aerial insulated cable and power transmission system

Abstract

The invention relates to the technical field of wires and cables, in particular to an optical fiber composite aerial insulated cable and a power transmission system. The optical fiber composite aerialinsulated cable comprises an optical fiber unit tube, a hard aluminum wire core, conductive wire layers, a conductor shielding layer, an insulating layer and an insulating shielding layer. The optical fiber unit tube and the hard aluminum wire core are positioned in the stranded conductive wire layers. Compared with the prior art, the optical fiber composite aerial insulated cable and the power transmission system have the advantages that an optical fiber communication function and an electric power transmission function are fused in the optical fiber composite aerial insulated cable with thesetting, accordingly, data can be transmitted by the optical fiber composite aerial insulated cable in a high-reliability manner as compared with a transmission cable with a single function, and connection can be facilitated as compared with the transmission cable with the single function; temperature, stress and load capacity information of various locations of power transmission line networks can be monitored by the power transmission system with the optical fiber composite aerial insulated cable in real time, accordingly, manual inspection can be omitted, real-time information can be obtained by the aid of wire network data transmitted by the optical fiber composite aerial insulated cable of the power transmission system and Brillouin optical time-domain analyzers by means of analysis,and the like.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to an optical fiber composite overhead insulated cable and a power transmission system. Background technique [0002] At present, my country's power system communication mainly realizes optical fiber communication on the main line by erecting optical fiber composite overhead ground wires and all-dielectric self-supporting optical cables. There is no ground wire in the line itself, and it is impossible to erect optical fiber composite overhead ground wires; Insufficient strength margin of spanning and pole towers limits the ability of all-dielectric self-supporting optical cable erection lines to achieve optical fiber communication by erecting optical fiber composite overhead phase lines. For no ground wire or single ground wire, especially insulated wires for urban and rural distribution networks Overhead lines are difficult to erect optical fiber composite overhead ground wi...
