Answer: OPGW installation is more complex and typically more expensive. Because it is a metallic ground wire, the installation usually requires a power shutdown. Its heavier weight and specialized hardware also contribute to higher material and labor costs.

ADSS cable is significantly easier and more cost-effective to install. Its non-conductive nature allows for live-line installation (without a power outage), which minimizes disruption and saves on project costs. Its lightweight design also requires less complex equipment and hardware.
