In a recent development, the use of Optical Ground Wire (OPGW) in power transmission systems has been under scrutiny for safety concerns. OPGW is a type of ground wire that contains optical fibers and is installed on transmission towers to provide communication and lightning protection.
According to experts, the OPGW ground wire can pose a safety hazard if it is not installed and maintained properly. The most significant risk is the possibility of a live wire falling on the OPGW ground wire, which can create a dangerous situation for maintenance personnel and the public.
To address these safety concerns, power transmission companies are being urged to adhere to strict installation and maintenance guidelines for OPGW ground wires. The guidelines include ensuring that the OPGW ground wire is installed at a safe distance from the power line and that it is adequately grounded to protect against electrical shocks.
In addition, regular inspections of the OPGW ground wire are recommended to identify any signs of wear or damage that could compromise its safety. The use of drones equipped with high-resolution cameras and sensors has proven to be an effective way to inspect OPGW ground wires in hard-to-reach areas.
While OPGW ground wires have proven to be an efficient and cost-effective way to provide communication and lightning protection in power transmission systems, it is essential that they are installed and maintained correctly to prevent accidents and ensure public safety. As power transmission companies continue to expand their use of OPGW ground wires, it is critical that they prioritize safety and invest in the necessary resources to ensure proper installation and maintenance.
