Dry-type transformers, including either cast resin or VPI technology, are well suited to applications in the renewable energy sector across Africa, particularly in energy generation by solar power installations and wind farms. There is a high non-linear load demand in renewable energy applications because of the use of inverters and our transformers are custom-designed to accommodate the high harmonic content present in these inverters.
Solar energy projects are usually located in areas where ambient temperatures are high, and we design fit-for-purpose solutions for these conditions. Solar plants also demand that transformers move from full load to no load every day. We design for these temperature variations, to accommodate regular expansion and contraction of windings.
Wind turbine applications also involve frequent changes in load, which our transformers can readily handle. We also custom design solutions for restricted installation height or footprint.
