Customised dry-type transformers at Electra Mining Africa

Considering the varying nature of operating conditions from one mine to another, Trafo Power Solutions, a spe cialist in the design and supply of dry-type transformers, will demonstrate at the upcoming Electra Mining Africa 2022 its flexibility and ability to tailor its solutions to meet specific site and customer needs. “Through many years of experience in the mining in dustry, pretty much across all commodities, we have rec ognised that each mine is different and has its own set of challenges,” says David Claassen, Managing Director of Trafo Power Solutions. “A one-size-fits-all approach is not appropriate, and this is why most of our products are custom-designed and -manufactured to suit specific site conditions.” Because they use air as a cooling medium, dry-type transformers are typically installed in indoor environ ments. However, Trafo Power Solutions has a wealth of experience in supplying dry-type transformers for out door applications as well. The design of the enclosure is critical to withstand the commonly harsh conditions as sociated with high dust and moisture levels. Despite the restrictive nature of enclosures, the company’s custom design capability guarantees adequate ventilation, while allowing for the necessary levels of ingress protection to

keep dust and moisture at bay. “With our in-house de sign capability, we are able to custom engineer solutions particularly for

challenging underground applications. We can tailor the dimensions, weight and other factors to match the space constraints presented by vertical shafts or decline shafts which are used to take the transformer underground,” Claassen adds. In the context of a renewed focus on environmental, social and governance (ESG) principles in the mining industry, Claassen says Electra Mining Africa presents an opportunity for the company to showcase how its solutions – dry-type transformers, modular-type and min iature substations, among others – meet the growing re quirement for environmentally friendly solutions. As well as sustainability, mines are continually push ing for progress in safety. The safety imperative is one of the key drivers for using dry-type transformer technology in the mining sector, Claassen says.
