E and I Zambia helps power up process plant for copper miner

Electrical control and instrumentation specialist, E and I Zambia, says it has successfully completed a large project on a new process plant for one of Zambia’s leading copper miners.

The contract included the installation of six electrical substations, 20 transformers, five 1,250 kVA diesel generators for back-up power and a 950 m overland conveyor. Almost 250 km of cable was pulled and nearly 15 km of cable racking was constructed, according to the company.

Also completed were six earth mat rings, 12 mast lights and a range of general plant earthing and lighting installations around the plant, as well as the fitting and termination of instruments. E and I Zambia conducted the work between January 2019 and April 2020, in close collaboration with both a leading design house and the end-client, the company said.

According to Projects Manager, Dave Opperman, the company has a sound track record in the country, having been active on the copperbelt and beyond since 2002.

“The experience of our team on site, the quality of our artisans and the training of workers ensured that the quality of this job was world class,” Opperman says. “While prioritising safety and quality, we were still able to adapt to the inevitable fine-tuning of project parameters and schedules, and to deliver on the client’s timelines.”

The safety standards were reflected in the achievement of 395 Lost-Time Injury Free days. This was achieved despite a busy site – peak manpower grew to over 270 employees and subcontractors – in a project that consumed almost 590,000 manhours. Almost all the staffing on the project was local, the company said.

“Being so well established in Zambia, we have a solid database of skilled artisans that we can draw upon for large projects like this one,” Opperman says. “The country has a good foundation of these trades, and we can select the most suitable profile of skills to match the project.”

He noted that the company is also able to optimise its local procurement through its network of reliable suppliers, while maintaining a strong cross-border supply chain for large and specialised equipment and components from South Africa.

In line with quality standards, each phase of the project involved the sign-off of both in-house and external quality control officers. This ensured all work was carried out in accordance with engineering designs and industry standard specifications before being certified ready for use.

E and I Zambia is also able to draw on the extensive technical capacity of South Africa-based EnI Electrical, an operating entity within Zest WEG
