Dry-type transformer specialist Trafo Power Solutions will supply two custom-engineered mini-substations to a significant motor plant expansion near Pretoria. <\/p>\n\n\n\n
The two units will be located outdoors, serving to power the lighting system and security requirements of the facility, as well as other loads. While most mini-substations are equipped with conventional oil-cooled transformers, these units have dry-type transformers \u2013 delivering a number of benefits to the customer. <\/p>\n\n\n\n
David Claassen, managing director of Trafo Power Solutions, says these include security and environmental factors.<\/p>\n\n\n\n
\u201cUsed by both the private and public sector, mini-substations must often be located in unprotected areas, making them vulnerable to vandalism and theft,\u201d Claassen says. \u201cThe oil-cooled transformers are often targeted for the copper in their windings, as well as the oil for the cooling system.\u201d<\/p>\n\n\n\n
The dry-type transformer\u2019s windings, by contrast, are cast in resin so the copper or aluminium cannot be readily accessed. There is also no oil to harvest, further reducing the incentive for criminals to destroy the structure. <\/p>\n\n\n\n
\u201cIn terms of environmental considerations, the dry-type transformer does not require any additional protective structure like walls or bunds to contain leaking oil or fire,\u201d he says. \u201cThese units also require very little maintenance, easing the managerial and technical burden on the owner.\u201d<\/p>\n\n\n\n
While these two transformers are manufactured in TMC Transformers\u2019 world-class facility in Italy, the design and manufacture of the balance of the mini-substation is carried out in South Africa. This gives Trafo Power Solutions a high level of control over the quality of the final product, says Claassen.<\/p>\n\n\n\n
\u201cThis also allows us to fully test the equipment locally before it is delivered, installed and commissioned on site,\u201d he says. \u201cWe embrace the opportunity to manufacture locally as much as we can, to support local industries and enhance job creation.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
