In April 2014, Hydro de Cahora Bassa completed the Apollo-Cahora Bassa 533 kV Transmission Line project. Transmission Grid Consulting served as the project’s prime contractor, with Mkhulu Electro Distribution Projects (Pty) Ltd. serving as the subcontractor.
This project’s scope of work comprised the replacement of a 5.6km piece of Quad ACSR Zambesi conductor (31.8 mm) on a 533 kV line that spanned the Limpopo River basin. The replacement was required due to the existing conductor’s wear and tear, which posed a risk to the transmission line’s efficient operation.
Because the wetlands in the area were inaccessible, the project had to be completed under extremely difficult conditions. However, the team was able to overcome this obstacle by stringing through the wetlands using a helicopter. This strategy enabled the project to be completed efficiently and safely.
Despite the challenges, the project was completed within a month of the order’s confirmation. The project’s successful completion insured the transmission line’s continuous and efficient operation, adding to the region’s overall development.

The Challenge :
There were several challenges that the project team may have faced during the erection of 69 towers and stringing 42 kilometers of the line for Eskom in 2005. Some of these challenges could include:
Terrain: Tower erection and line stringing may have been harder in rocky or mountainous terrain.
- Weather: Weather may have hampered the project. Rain or heavy winds could have slowed operations, making project deadlines impossible.
- Safety: Working with high-voltage power transmission cables requires safety. The team may have struggled to teach and equip project personnel safely.
The Result :
To overcome these challenges, the project team may have implemented several strategies, including:
- Planning and preparation: The team may have analyzed the site to discover topographical or weather issues that could affect the project. They may have also trained and outfitted workers with safety gear to work safely on the job.
- Flexibility: The crew may have added time to the project plan for weather or terrain difficulties. They may have been adaptable to shifting work situations.
- Collaboration: Transdeco, the main contractor, and Mkhulu Electro Distribution Projects cc, the subcontractor, may have collaborated to execute the project on schedule and within budget.
