Mozambique, Maputo: Trafo Power Solutions has supplied dry-type transformers for a large liquified natural gas (LNG) project in northern Mozambique.
The transformers are ensuring the safe and reliable operation of substations in the construction camp.
According to David Claassen, managing director of Trafo Power Solutions, 18 dry-type transformers were included in modular substations built in South Africa and shipped to site recently. The company is in a strategic partnership with leading Italian transformer manufacturer TMC Transformers.
“These substations are for the project’s first construction camp of about 9,500 contractors,” Claassen says. “Our transformers have been specially designed for the high ambient temperatures in northern Mozambique.”
Ranging from 500 to 1250 kVA, the temperature of these units will rise to a maximum of only 80 ⁰C when under full load. With Class-H insulation on both the medium voltage and low voltage windings, they will withstand a temperature of 180⁰C. The transformers are also designed for levels of humidity up to 95 %. As they do not contain oil, they pose no fire, explosion or environmental hazard.
“A transformer containing oil would present a significant risk in a construction camp accommodating thousands of people in close proximity,” Claassen says. “The safety level of dry-type transformers also means that they can be used in enclosed spaces like modular substations. The minimal maintenance required is an added advantage, being located on such a remote site.”
Claassen notes that the global competition to supply this mammoth project has been intense, and points to the vital partnership between the local knowledge and experience of Trafo Power Solutions, and the technology and expertise of TMC Transformers.
