High-strength optical fiber composite cable

Abstract

The invention discloses a high-strength optical fiber composite cable, and the center of the cable is provided with a reinforcing filling body composed of glass silks. The reinforcing filling body is provided with three first circular holes, and the interior of each first circular hole is provided with an insulating optical fiber composite wire core. The exterior of the reinforcing filling body is provided with a fireproof layer with the thickness from 2mm to 3mm, and the exterior of the fireproof layer is provided with a metal armored layer with the thickness from 2mm to 3mm. The exterior of the metal armored layer is provided with a stress control tube with the thickness from 4mm to 6mm, and the stress control tube is wrapped by an aluminum sheath with the thickness from 2mm to 3mm. The stress control tube is provided with one second circular hole, and the interior of the second circular hole is provided with a standby optical fiber unit. The cable improves the capability of optical fibers in bearing tension and pressure, improves the safety in a normal use process, prolongs the service life, and greatly reduces the operation cost of a power system.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a 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 the optical fiber Durin...

[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 the optical fiber During the manufacture and use of low-voltage cables, the optical unit is easily damaged by external forces, which will cause the optical fiber low-voltage cables to fail to operate normally, or even be scrapped
