MOZAMBIQUE - Trafo Power Solutions has supplied dry-type transformers for substations in a construction camp at a large liquified natural gas (LNG) project in the north of the country.

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 the Italian transformer manufacturer TMC Transformers.

"These substations are for the project's first construction camp of about 9,500 contractors," said Claassen. "Our transformers have been specially designed for the high ambient temperatures in northern Mozambique."

Ranging from 500 kVA to 1250 kVA, the temperature of the units should rise to a maximum of only 80⁰C when under full load. With Class-H insulation on both the MV and LV windings, they are expected to withstand a temperature of 180⁰C. This is considerably more than the potential 40⁰C ambient temperature in the tropics plus the 80⁰C temperature rise. The transformers are also designed for humidity levels of up to 95%.
