Trafo Power Solutions, experts in dry-type transformers, has recently completed a contract as part of a significant upgrade at a Mpumalanga coal mine. <\/p>\n
This involved the design, supply and installation of two 200 kVA \u2013 22 kV to 400 V \u2013 dry-type transformers, according to Trafo Power Solutions managing director David Claassen. Housed in specialised IP42-rated ingress protected enclosures, the units were specified by a design house on behalf of the end-customer.<\/p>\n
\u201cThe contract demonstrated our application engineering capability, and our experience in co-ordinating our solution within a larger project,\u201d Claassen says. \u201cThis included meeting detailed specifications, and ensuring that our design for the transformers and their enclosures matched the requirements and constraints of the site.\u201d<\/p>\n
Trafo Power Solutions also equipped the units with the necessary earth fault protection and surge protection, as well as vibration pads. <\/p>\n
\u201cDry-type transformers are well suited for the coal mining environment, with its hazardous areas and its regulations to mitigate fire risk,\u201d he says. \u201cThe dry-type technology uses air to cool the transformers, doing away with the need to use oil as a coolant.\u201d<\/p>\n
Claassen emphasises that the absence of oil has advantages for safety, as the possibility of oil igniting is removed. The units can also be well protected against fine airborne coal dust. An added advantage is environmental, as there is no chance of an oil leak contaminating the ground or water.<\/p>\n","protected":false},"excerpt":{"rendered":"
