Double strand opgw optical cable and its processing method

Abstract

The invention discloses an OPGW (Optical Fiber Composite Overhead Ground Wire) optical cable, particularly a double-stranded OPGW optical cable which structurally comprises a main group and a subgroup. The improved OPGW optical cable, which is provided by the invention and can flexibly, independently and locally establish monitoring communication at an actual monitoring point according to the actual condition of a line without influencing an existing communication transmission circuit of the line, comprises a main group optical cable consisting of an inner layer aluminium-covered steel wire, main group optical fiber units and outer layer aluminium-covered steel wires; and a subgroup optical cable is arranged outside the main group optical cable. Meanwhile, the invention also provides a processing method of the OPGW optical cable. After the double-stranded OPGW optical cable disclosed by the invention is adopted, the main group optical cable and the subgroup optical cable are relatively independent, so that when a monitoring signal needs to be transmitted, the subgroup optical cable at the monitoring point only needs to be cut off, and thus, communication of substations at both sides of the optical cable and a system cannot be influenced. Moreover, by adopting the double-stranded OPGW optical cable disclosed by the invention, erection of the line can be completed for once; the double-stranded OPGW optical cable is simple for construction; and more cost does not need to be increased.

Description

technical field [0001] The invention relates to an OPGW optical cable and a processing method thereof, in particular to a double-strand OPGW optical cable structurally comprising two parts of a main group and a subgroup. Background technique [0002] OPGW (Optical Fiber Composite Overhead Ground Wire) optical cable refers to an optical cable placed in the ground wire of overhead high-voltage transmission lines to form an optical fiber communication network on the transmission line, which has dual functions of ground wire and communication. With the erection of power lines, OPGW optical cables have many advantages such as saving construction costs, high reliability, high safety, and long life, so they have become the main transmission medium for power system communications. With the development of power grid technology, it often crosses uninhabited areas and mountainous areas with inconvenient transportation. The geographical environment and climatic conditions are harsh, and...

Problems solved by technology

At this time, if the traditional OPGW optical cable is used, since its structure is composed of a group of optical fibers, when one of the optical fibers needs to be used as a monitoring communication optical fiber, the entire optical cable needs to be disconnected at the actual state monitoring point, so that It not only affects the communication of substations on both sides, but also may cause the interruption of the entire transmission network scheduling, affecting the safety and normal operation of the transmission network
