Problems solved by technology

[0003] However, the disadvantages of the current existing technology are: the existing technology can only transmit electric energy or realize optical fiber communication, thus causing multiple constructions of multiple lines such as electric wires, network cables, telephone lines, and cable TV lines, which greatly wastes wires. Cable resources and pipeline resources

Embodiment Construction

[0016] Such as figure 1 As shown, an optical fiber composite low-voltage cable according to the present invention includes a cable core, the gap in the cable core is filled with a filling layer 4, and a tape layer 3, an armor layer 2 and a sheathing layer are sequentially wound concentrically outside the cable core. The jacket layer 1; the cable core is formed by twisting the insulated core 6 of the low-voltage power cable and the optical cable 5 concentrically.

[0017] The cable core of the present invention is composed of a low-voltage power cable insulated core and an optical cable with a twisted core structure of 2 cores + 1, 3 cores + 1 or 4 cores + 1. Metal layer twisted filled optical cable, non-metallic central tube dry type optical cable or non-metallic central tube filled optical cable; low-voltage power cable insulation core 6 is covered with plastic insulating layer; tape layer 3 and filling layer 4 are flame retardant Material layer; the armor layer 2 is a doubl...

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 ...
