Polytra NV, member to the Worldwide Project Consortium (WWPC) for Belgium, just finished the delivery of 1 x 50 MVA transformer weighing 58 ton and 1 x 150 MVA transformer weighing 85 ton to two substations in Lubumbashi Katanga Province D.R.Congo.
The two transformers were shipped in Mumbai on board of a RORO vessel, then transshipped in Jeddah to arrive safe and sound in Durban South Africa. In Durban both units had to be stored in a safe area for more than 5 weeks before the trip of 2950 km to the DRC could begin.
Once arrived the transformers were discharged from the lowbeds onto rail by jacking and sliding method. The whole operation including the storage period took about 12 weeks. The experts from Polytra did encounter several obstacles, such as bad roads due to the hefty rainy season, red tape challenges, narrow entry and very sharp curves, but at the end all hindrances were conquered.
