Multi-phase optical fiber embedded power cable

Abstract

The invention relates to a multi-phase optical fiber embedded power cable. The power cable comprises an optical fiber cable, a plurality of cable assemblies for clamping the optical fiber cable, filler yarns, a lapped layer and an outer sheath, wherein the filler yarns surround the optical fiber cable and the cable assemblies; the lapped layer wraps up the optical fiber cable, the cable assemblies and the filler yarns; the outer sheath surrounds the lapped layer; the cable assemblies comprise copper core conductors and insulating layers wrapping up the copper core conductors; the optical fiber cable comprises a fiber reinforced composite strengthened core, a plurality of optical fibers for clamping the strengthened core, filled strips, an aramid fiber layer and an outer sheath; the filledstrips surround the strengthened core and the optical fibers; the aramid fiber layer wraps up the fiber reinforced composite strengthened core, the optical fibers and the polyethylene filled strips; and the outer sheath covers the aramid fiber layer. The invention provides low-cost and convenient schemes such as integration of optical and power cables into one and one cable with multiple purposesfor fiber to the home, four networks in one (power, telephone, television and computer), ammeter remote metering and interaction with power consumers of the smart grid.

Description

technical field [0001] The patent of the present invention relates to a special power cable, especially a multi-phase electric optical fiber embedded power cable, which is used for 400v low-voltage power supply network lines. Background technique [0002] In the construction of smart grid, it is necessary to strengthen the technical means of user load measurement monitoring and information communication at the end of the power grid (400V power supply network). [0003] Due to the current power carrier communication technology implemented on conventional power cables, due to its low speed, low communication success rate, and low reliability, it can no longer meet the needs of large-capacity real-time information communication for remote control, measurement, and monitoring of electric power in smart grids. [0004] In the construction of an information society, as telephones, computers, and televisions enter thousands of households, enterprises engaged in telecommunications, ...
