TransGrid has begun early works for the future communication upgrade of the Williamsdale to Cooma Transmission Line.
The project involves installing a new fibre optic cable to the existing line which is approximately 74km long.
The optical ground wire (OPGW) we are planning to install along the existing length of the line performs the conventional task of providing the electrical ground wire of the network whilst the optical fibres within the cable create an independent telecommunications system.
This project involves upgrading the telecommunications link between TransGrid's Cooma and Williamsdale substations.
Some of the works involve:
Installation of OPGW 48 core on the Williamsdale to Cooma 978 Line, which is a 132 kV single circuit wood pole line approximately 74km in length.
Construction/upgrading of approximately 6.5km of access tracks, 31 pads and two minor earthworks.
Ground line reinforcement of approximately six structures.
Installation of approximately 17 OPGW joint boxes.
Installation and testing of OPGW termination equipment, conduit and associated facilities for running the fibre optic cable into the Main Communications Room at Williamsdale and Cooma substations.
We have engaged the Zinfra Group to undertake this work on our behalf and are still finalising our work for the site access requirements for this project.
It is anticipated that site mobilisation will begin in early 2016 with the project to be completed by the end of 2016.
