OPGW (Optical Ground Wire) is a type of cable that combines optical fibers and metallic conductors. It is used in the electric power transmission and distribution industry to provide both a means of communication and electrical grounding. The optical fibers within the OPGW cable are used for communication purposes, such as monitoring the status of the power line and transmitting data. The metallic conductors provide the electrical grounding necessary to protect the power line from lightning strikes and other electrical disturbances.
When selecting an OPGW cable solution, factors such as the number of fibers, fiber type, metallic conductor size and type, and the cable's ability to withstand environmental factors should be considered. The OPGW cable should be designed to meet the specific requirements of the power transmission system and should be able to withstand the mechanical and thermal stresses that may be encountered during installation and operation.
Proper cable management is essential in the installation and maintenance of OPGW cables. The cables should be properly labeled and routed to prevent interference and reduce downtime. Regular inspection and maintenance of the OPGW cable system should be carried out to ensure its safe and reliable operation.
