Radian TRC

Radian TRC is a specialist power transformer manufacturer located in Heidelberg – GP, Gauteng, South Africa. With a focus on power transformers, they offer a range of products including Rectifier Transformers, AC & DC Furnace Transformers, Convertor Transformers, Distribution Transformers, Transductors, and Reactors. Their products cater to a variety of industries and applications, providing solutions for different voltage and current requirements.

In terms of power transformer range, Radian TRC specializes in 1 MVA to 20 MVA with HV voltages in the 3.3 kV to 33 kV range. However, they are open to considering ratings outside of this range. They also offer high current reactors in steel core and air core varieties, as well as high current, high voltage range transductors for diode rectifier applications.

Radian TRC is constantly innovating and developing new solutions for their customers. They are currently working on a compact, integrated rectiformer that combines a rectifier transformer and rectifier in a simple and robust design, specifically aimed at electrolysis-based processes.

Their range of Rectifier Transformers covers various configurations, including the common 3 phase bridge rectifier and the 6 phase double star with inter-phase transformer. They also offer extended delta, phase shifted transformers for twelve pulse (12P) plants where impedance and voltage matching are critical.

For the smelting industry, Radian TRC provides AC and DC Furnace Transformers. DC Electric Arc Furnace (EAF) transformers have a design similar to rectifier transformers but with more taps and on-load tap-changers. AC EAF transformers require a more conservative design due to repeated short circuit conditions and are often built as single-phase units.

In addition, Radian TRC offers Convertor Transformers optimized for variable speed drives (VSD) in motor control. These transformers are designed to accommodate the harmonics generated by VSD drives. They are typically rated at 100% capacity, compared to distribution transformers which are rated at 80% capacity.

As for Distribution Transformers, Radian TRC offers a standard range that follows SABS 780. They range from small pole-mounted units to larger units in distribution yards and substations, using robust oil-natural, air natural cooling. They are also capable of manufacturing non-standard ratings and voltages according to customer specifications.

Radian TRC’s Transductors (Saturable Reactors) provide a robust control mechanism for high current, high voltage range requirements of DC furnace applications. These transductors use two controlled DC current sources and are transferable to all DC process applications.

Lastly, Radian TRC offers Reactors in both gapped steel core and air core varieties. The gapped steel core reactors, immersed in oil, provide well-controlled reactance and effective cooling for high current applications. On the other hand, air core reactors are used in AC and DC furnace applications to prevent saturation. Water or oil cooled busbars are often used for larger current ratings.

Radian TRC prides itself on providing quality products and solutions for various power transformer needs. For more information, interested parties can contact Radian TRC through their website or at their office located at 3 Chris Street, Industrial, Heidelberg – GP, 1441, South Africa.
