Optical Ground Wires (OPGW) are a unique type of cable used in the power transmission industry. It combines the traditional functions of a ground wire with the added benefits of an optical fibre cable. OPGW cables are used for various purposes, including power transmission, communication, and lightning protection.

Applications of OPGW Cables

OPGW cables are primarily used in the power industry for the following purposes:
Power transmission

OPGW cables are used for transmitting high voltage power over long distances. The optical fibres embedded in the cable allow for real-time monitoring of the power transmission line, making it easier to detect faults and take corrective measures.


OPGW cables can be used for high-speed communication and data transmission. They are often used for establishing telecommunication networks along power transmission lines.

Lightning Protection

OPGW cables are designed to provide lightning protection for power transmission lines. The optical fibres in the cable act as a lightning arrestor, dissipating the energy from lightning strikes.
