OPGW (Optical Fiber Composite Overhead Ground Wire) cables are available from multiple suppliers, including AFL, RLBCable, ZTO Fiber Cable, American Tech Supply, and Incab America, with stock options for immediate purchase.

Overview of OPGW

OPGW cables are dual-function cables used in high-voltage transmission lines, combining grounding and lightning protection with optical fiber communication capabilities . They are typically installed at the top of transmission towers to shield conductors from lightning while providing a secure path for data transmission . The cable construction often includes stainless steel tubes or aluminum-clad steel wires protecting the optical fibers, with designs such as Central Loose Tube, AlumaCore, HexaCore, and CentraCore to accommodate different fiber counts and mechanical requirements .
