Multi-core self-cooling high-strength optical fiber composite cable

Abstract

The invention discloses a multi-core self-cooling high-strength optical fiber composite cable. The center of the cable is provided with a reinforcement filler made of glass filaments. The reinforcement filler is provided with three first circular holes, and each first circular hole There is an insulated fiber optic composite core, a refractory layer with a thickness of 2-3mm is provided outside the reinforced filler body, a metal armor layer with a thickness of 2-3mm is provided outside the refractory layer, and a metal armor layer with a thickness of 4-3mm is provided outside the metal armor layer. 6mm stress control tube, the stress control tube is equipped with a cooling tube equipped with cooling liquid, and the cooling tube is extruded with an aluminum sheath with a thickness of 2-3mm; the stress control tube is provided with two symmetrical second circles hole, and a group of optical fiber units as a spare is arranged in the second round hole. The invention increases the ability of the optical fiber to bear tension and pressure, improves the safety of the cable during normal use and prolongs the service life of the cable, greatly reduces the operating cost of the power system, and has a self-cooling function to ensure the performance of the cable.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a multi-core self-cooling high-strength optical fiber composite cable. Background technique [0002] With the development of society, high-strength optical fiber power cables are integrated with optical units in traditional power cables. They are cables with power and optical communication transmission capabilities. The laying of optical cables is completed while laying cables. Photoelectric integration, while transmitting electric energy, can realize signal transmission on the same network, and can detect the working status of the line online. [0003] As the State Grid and China Southern Power Grid increase 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 are pushing power fiber to the home at the user end. The optical cables are made of non-metallic materials, so ...
