WEG’s withdrawal boards boost uptime at Ghana gold plant

A process plant at a gold mine in Ghana has become the first in Africa to install WEG’s fully withdrawable WEG CCM06 boards, which safely improve the plant’s flexibility when isolating selected circuits for maintenance and repair.

“The customer’s existing motor control centre (MCC) regulated many operations, which all had to be shut down when attending to a single item of equipment,” says Foster Yeboah, regional sales manager for West Africa based at Zest WEG’s Ghana branch. “This led to significant downtime, which the customer wanted to avoid.”

The mine required a solution which would allow the plant to isolate the electrical feed to specific equipment, allowing targeted maintenance to be conducted on those items without necessitating a complete plant shutdown, says Yeboah. The answer came in the form of a double containerized electrical house or E-house with a key element of this solution being the fully withdrawable boards.

Plant’s efficiency

“The WEG CCM06 boards are compartmentalized functional units which can be turned off and pulled out, without affecting the power to the other units,” he explains. “This is a valuable feature when considering that important equipment such as mills and discharge pumps must ideally operate continuously to keep the plant efficient.”
