With engineering and construction support from Zafas Sdn Bhd, Tenaga Nasional Berhad began their double circuit Senibong – Plentong uprating project using double-bundled Lisbon size ACCC® Conductor to replace double bundled ACSR Batang conductor.

The use of ACCC Conductor will allow TNB to increase the double circuit line capacity from 600 to 1,000 MVA without replacing or modifying any of the 35 existing steel lattice structures first installed over 25 years ago. The upgraded line operating at 230 kV is linked to a submarine cable at the Senibong substation where it ties into the Singapore electric power grid. The line is being upgraded to accommodate growing demand for electricity in Singapore.

ACCC Conductor for the project was supplied by  Tenaga Cable Industries Sdn Bhd (TCI) and hardware was provided by Dervaux.  The 9.2 km double circuit project includes two major highway crossings. Tesmec pullers and tensioners are being utilized along with NingBo sheeve wheels. Duratrans’ ACCC Master Installers Mr. Shariff and Mr. Zul are supervising the project, with additional support from CTC Global’s Engineering and Field Service Departments.
