Optical-fibre composite low-voltage cable

Abstract

The invention discloses an optical-fibre composite low-voltage cable, comprising a cable core, wherein a filling layer is filled in a gap in the cable core, and a belting layer, an armouring layer and a jacket layer are concentrically wound outside the cable core in order; and the cable core is formed by concentrically twisting a low-voltage power cable insulated wire core with an optical cable. According to the optical-fibre composite low-voltage cable disclosed by the invention, a power cable and a communication optical cable are combined in one cable, and the co-network signal transmission of a telecommunication network, a broadcast and television network, and the Internet can be realized while electric energy is provided, and thus providing convenient and modern lifestyle for users.

Description

technical field

[0001] The invention relates to the field of power cables, in particular to an optical fiber composite low-voltage cable. Background technique

[0002] As the State Grid increases the construction of smart grids, in addition to vigorously building high-voltage and ultra-high-voltage large-capacity transmission lines for the backbone network, it is also pushing power fiber-to-the-home at the user end. On June 13, 2010, the State Grid Corporation of China held a symposium on the pilot project of power fiber-to-the-home in Shenyang, Liaoning Province, marking the full launch of the power fiber-to-the-home pilot project. The main innovation of the optical fiber composite low-voltage cable is to integrate the power cable and the communication optical cable into one cable. While providing electric energy, it also realizes the same network signal transmission of the telecommunication network, radio and television network, and the Internet, providing users with more ...
