Tata Power’s project team has designed and proposed to build a novel three-circuit high-tension transmission tower at a Mumbai Metro construction site.
Carrying 220 kV power lines overhead, the tower will facilitate clearance of obstructing transmission lines over the Mumbai Metro rail network between Amar Mahal, Ghatkopar and Vikhroli.
The project will be completed by December 2021. This innovative tower will be constructed at a cost of Rs one crore under all safety precautions.
The project will benefit both the Mumbai Metropolitan Regional Development Authority (MMRDA) and consumers by saving Rs 30 crore per circuit on infrastructure development and by ensuring uninterrupted power supply during the construction work.
In case of some other project, the MMRDA would have been left with no option but to lay an underground network, a mammoth task to execute.
The main objective behind this innovative tower design was to lay down a section of the proposed network of the Mumbai Metro rail below the existing EHV transmission lines of Tata Power.
In order to implement the same, a detailed analysis was carried out by the project team to arrive at an innovative design of three-circuit (in contrast with the conventional one, two or four circuit towers).
After finalising the structural drawing in consultation with the designing body, the company’s project team proposed to raise the height of the tower from 35.7 mtr to a record 50.1 mtr without affecting the regular power supply to Mumbai Metro.
By doing this, it aims to ensure the rapid development of public transport infrastructure while maintaining reliable, uninterrupted and quality power supply.
