ACTOM Distribution Transformers (ADT) has expanded its product range to include transformers rated from 5MVA to 10MVA (Class 1), with voltages up to and including 66kV. These small power transformers are offered with off-load and on-load tap changers.
The tap changer for the on-load option is from Maschinenfabrik Reinhausen (MR). Mazwi Gordon Dubase, ADT Manufacturing Manager, said, “For the smaller transformers, we use the MR ECOTAP, resulting in a more compact transformer.”
ADT offers solutions for standard step-down transformers, generator step-up transformers, PV, VSD, and K-rated transformers, as well as dual secondary transformers. Customers can replace mineral oil (ONAN) with Ester fluids (KNAN), making the transformers more environmentally friendly. Losses can also be optimised to reduce the carbon footprint.
ADT’s facility has large foil winding machines accommodating multiple foil sizes and widths. The large stacking tables enable the core and coils to be assembled easily, and they also have vast, automated vapour phase drying ovens that easily accommodate these fully assembled active parts. Its overhead crane capacity enables them to lift 30 Tons.
ADT’s test facility is also equipped for in-house testing. In addition to full routine testing, it offers temperature rise, Lightning Impulse, Partial Discharge, Sweep Frequency Response Analysis, and sound level measurement. ADT’s in-house designs comply with international (IEC) and local specifications (SANS).
ADT has ventured into this segment with multiple requests from customers. Power Transformer manufacturers often overlook the size of transformers as they are seen as too small. Lead times also play a vital role. The power demand has recently increased, so ADT positioned itself to fill the gap in this segment. “With our short lead times, competitive pricing and stringent quality control processes, we aim to satisfy the markets with our increased product offerings”, said Mbenge.
ACTOM Distribution Transformers has the perfect range of transformers across the wide voltage spectrum. ADT’s facility is ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 and SANS accredited.
