Client: Oman Electricity Transmission Company (OETC)
Main Contractor: Majan Telecommunication
Scope of Work: OPGW Conductor Replacement
Project Overview
This project involved the replacement of the Optical Ground Wire (OPGW) conductor along the Barka – Sohar transmission corridor, a vital 220 kV power route in Oman. The scope demanded high precision and safety measures, as the work was carried out on live transmission lines critical to the national grid.
Work Details
-
Dismantling of existing OPGW conductors with careful handling to avoid damage to operational towers and insulators.
-
Installation of new OPGW conductors, ensuring improved communication and system monitoring capabilities.
-
Splicing and Jointing Works carried out using specialized equipment and skilled technicians.
-
Testing & Commissioning to confirm seamless integration with the grid’s communication and protection systems.
Challenges & Solutions
-
Live Grid Environment: Work was executed under strict OETC safety protocols to ensure uninterrupted power supply.
-
Weather & Terrain: Stringing and replacement required advanced tensioner-puller machines to maintain conductor stability.
-
Integration: Precise splicing and testing ensured zero signal loss and reliable communication between substations.
Outcome
The project was successfully completed within schedule, delivering a modernized OPGW network that strengthened OETC’s transmission monitoring, protection, and data communication systems. It enhanced grid reliability and positioned the network for future smart grid integration.
