Optical Ground Wire (OPGW) is a dual-purpose cable used in power transmission and distribution networks, combining grounding and high-speed data communication in a single design.
Installed at the top of high-voltage transmission towers, its conductive outer layer provides effective grounding and shields the conductors from lightning strikes.
Integrated optical fibres within the cable enable secure, high-bandwidth data transmission for network monitoring and telecommunications.

110–500kV
Conductor:
Aluminum-clad steel or all-aluminum strands
Sheath:
Aluminum or aluminum-clad steel tubular, or optional polymer for special protection
Mechanical Protection:
Steel strands for tensile strength; may include a fiber-reinforced layer
Colours
Sheath Colour:
Silver/metallic (natural aluminum or steel)
Application Standards:
IEC 60794, IEEE 1138
