Problems solved by technology

Due to the development of passive optical network (PON) technology, the access problem of the "last mile" of the power grid can be completely solved through the combination of photoelectric composite cable and passive optical network, but the construction is relatively complicated. If a low-voltage optical fiber can be provided Composite cables (low voltage refers to 0.6 / 1KV), not only can solve the "last mile" access problem of transmission lines, realize the "four-network integration" of power optical fiber to the home, but also meet the requirements of online measurement of low-voltage photoelectric composite cable power units The operating temperature can be wired once during construction, which simplifies the complexity of construction and will meet the current needs

Abstract

The invention relates to an optical / electric compound cable which comprises a power transmission and distribution cable and an optical unit, wherein the optical unit is arranged in the power transmission and distribution cable; the optical unit comprises a sheath, a reinforcer and two or more than two optical fibers; and the reinforcer and the optical fibers are arranged in the sheath. By utilizing the optical unit, the optical / electric compound cable realizes the function of communication, solves the problem of the access of the power transmission line for the last one kilometer, and realizes the power fiber access into households in four-network fusion way (power supply, wide band, television and talking). During construction, the cable can be arranged in one time, thereby simplifying the complex degree of construction and satisfying the current demands.

Description

technical field [0001] The invention relates to the technical field of electric power transmission and distribution lines and cables, in particular to a low-voltage optoelectronic composite cable in the "last mile" related technology of transmission lines. Background technique [0002] At present, the State Grid can solve the technical problems of power communication in the backbone network and distribution network through OPGW optical cable (fiber composite overhead ground wire), ADSS optical cable (all-dielectric self-supporting optical cable), OPPC optical cable (fiber composite phase wire), etc. The problem that needs to be solved is the access problem of the "last mile" of the power grid. Due to the development of passive optical network (PON) technology, the "last mile" access problem of the power grid can be completely solved by using the photoelectric composite cable plus the passive optical network, but the construction is more complicated. If a low-voltage optical ...
