Abstract

The present invention discloses a low voltage fiber composite conductor. The low voltage fiber composite conductor comprises a core body, and the core body is formed by twisting a plurality of insulating wire cores and a plurality of fibers. An inner protection layer is wrapped on the outside of the core body, and an outer protection layer is wrapped on the outside of the inner protection layer. Each insulating wire core is composed of a conductor and an insulating outer layer wrapped on the outside of the conductor, each fiber comprises a loose casing pipe and an optical unit placed in the loose casing pipe, and a fiber filler is arranged between the loose casing pipe and the optical unit. The low voltage fiber composite conductor of the present invention can realize the function fusion of the fiber communication and the electric power transmission in a low voltage power distribution network, is communicated with a device via an optical interface, fully utilizes the advantage of using the fibers to transmit data, and enables the data transmission rate to be improved. Further, by the redundancy design of more than two fibers, the data transmission reliability in the fibers is improved. By filling the fiber fillers, such as the fiber ointments, etc., between the loose casing pipes and the optical units, the influence of the stress effect on the transmission quality is reduced greatly, and the stable and reliable data and electric energy transmission are provided.

Description

technical field [0001] The invention relates to a composite wire, in particular to a low-voltage optical fiber composite wire. Background technique [0002] As the country vigorously promotes the "integration of three networks", the State Grid and China Southern Power Grid have stepped up the construction of smart grids. In addition to vigorously building high-voltage and ultra-high-voltage large-capacity transmission lines for the backbone network, they have also started the construction of pilot projects for power fiber-to-the-home , at the user end to promote power fiber-to-the-home (PFTTH) to serve the implementation of the national "triple play" strategy. Optical fiber composite low-voltage cables (Optical Fiber Composite Low-Voltage Cable, OPLC) are used in the low-voltage communication access network to lay optical fibers along with low-voltage power lines to realize smart meters to the home, and cooperate with passive optical network technology to carry electricity i...
