The 3M conductor is being installed in place of existing ACSR conductors, without the need to construct new transmission towers, as the right of way available was inadequate. The sag-resistant overhead conductor can carry twice the amount of electricity compared with conventional steel conductors of the same diameter, the company said.
This deployment adds India to the list of countries in which 3M ACCR is being used to boost transmission capacity in either densely developed or environmentally sensitive areas. The conductor allows capacity increases while avoiding the costs and disruptive effects of tower construction or acquiring additional rights of way. Some of the other countries in which 3M ACCR is in use are the US, Canada, Brazil and China.
Tim Koenig, director of the 3M High Capacity Conductor Program, said: “The installation of two double-circuit 110kV lines using lightweight 3M ACCR will provide a cost-effective long-term solution with minimal disruptive impact on the communities.”
The Borivali-Malad and Salsette-Saki line upgrades will require a total of 200 kilometers of conductor to cover circuits of eight kMs of each line. Installation of the Borivali-Malad circuits is complete. Installation on Salsette-Saki is planned in the near future.
