OPGW Overhead Conductor Greases
OPGW Overhead Conductor Greases (also called OPGW filling greases/jelly) are specialized, semi-solid, non-conductive filling compounds designed exclusively for Optical Ground Wire (OPGW) cables—hybrid structures that combine overhead power grounding (like ACSR) with optical fiber communication. They fill critical internal gaps to protect both the optical fibers and the metallic structural components.
