TLI Group are delighted to be able to bring you a significant update on one of our major transmission projects, namely the restringing of the Omagh Main to Dromore Main 110kV Restringing Project, which we are delivering on behalf of our valued client, Northern Ireland Electricity Networks (NIE Networks).
The project involves the refurbishment and strengthening of steel towers and concrete foundations, restringing of phase conductors and earth wire and the extension of towers T106 and T130. The tower body extensions are necessary to provide the required clearance for the proposed development of the A5 motorway.
The civil works for the project were completed over Q1 & Q2 2023. The outage works for the overhead lines commenced in early July, and after weeks of consultation, planning and programming, the tower body extensions scope at T106 and T130 were successfully completed last weekend. Each tower was extended by approximately 9 meters, which involved dismantling the existing tower, inserting the new section, and reconstructing the tower, associated conductors and the OPGW.
The tower extensions mark a significant milestone in the delivery of this project and for the future infrastructure development of the Northwest region, as it will address required clearance issues for the proposed development of the A5 motorway. Our restringing works which take in an upgrade in conductor to Totara 425mm2 AAAC and also earth wire upgrade to a 160mm2 Keziah equivalent OPGW will continue until October of this year across of the one of the busiest Northwest road networks.
TLI Group are proud to play an integral part in this project. The Omagh to Dromore 110kV transmission line is critical infrastructure that powers homes, businesses and public services in Northern Ireland and our work will ensure a safe and reliable network for many years to come.
