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:

  1. 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.
  2. Communication: OPGW cables can be used for high-speed communication and data transmission. They are often used for establishing telecommunication networks along power transmission lines.
  3. 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.

Installation of OPGW Cables

Our team of experts provide professional installation of OPGW cables. The installation process involves removing the existing ground wire from the transmission line and pulling the OPGW cable through the transmission line using specialised equipment. 

The cable is clamped at the tower ends and tensioned to the recommended value to ensure safe and correct installation.

We are one of the top Indian OPGW cable manufacturers in India, providing a wide range of OPGW cables designed to meet the specific needs of power transmission companies.
