Two new transmission lines using ACCC® conductors were recently commissioned in Bangladesh and Nepal, with the support of Indian contractors.
With the support of Kalpataru Power Transmission Ltd, Power Grid Company of Bangladesh (PGCB) completed its 400kV BSRM transmission project in Mirsharai, Bangladesh. This new 16.5-km double-circuit transmission line was built to supply power to one of South Asia’s largest economic zones which is under construction.
The 30,000-acre Bangabandhu Sheikh Mujib Shilpanagar Economic Zone is being developed by the Bangladesh Economic Zones Authority.
Currently energized at 230kV, this line will eventually be raised to 400kV and connect to the Koreghat Substation which is currently under construction. PGCB selected Dhaka size ACCC® Conductor which spanned approximately 383m between steel lattice structures. A 383m span was used to cross the Dhaka – Chittagong Highway.
Approximately 70 per cent of the line crossed through paddy-cultivated areas and the balance was through coastal area swamps, making access extremely difficult. Materials and equipment could only be transported by small boats during high tide conditions. Mangrove trees and shrubs exacerbated the handling challenges further. KPTL’s crews did a fantastic job of coordinating the delivery and movement of equipment and crews.
Apar Industries Ltd supplied the ACCC® Conductor and Dervaux provided ACCC® Hardware. ACCC® Installation support was provided by Master Installer Mr. N.J. Balaji.
ACCC® Conductor is an internationally patented and trademark registered product of CTC Global Corporation.
Second ACCC® Reconductor Project in Nepal
Using Silvassa-size ACCC® Conductor manufactured by Apar Industries Ltd, Nepal Electric Authority (NEA) completed its 33kV double circuit Duhabi – Khanar ACCC® Reconductor Project in Biratnagar, Nepal. NEA selected Silvassa-size ACCC® Conductor to replace dog-size ACSR conductor to substantially increase line capacity to support growing industrial demand without the need to replace or modify existing steel lattice structures in the densely populated residential area.
The average span length was 130m with a few longer spans crossing roads and a canal. ACCC® Hardware was supplied by Sicame India. Mudbhary and Joshi Construction Pvt. Ltd. provided engineering and installation support. CTC Master Installer, Mr. Mukesh Kumar Jha provided ACCC® training and installation support.
