Pollution control is a vital part of sustainable industrial development, and electrostatic precipitators (ESPs) play a key role in reducing particulate emissions from power stations and heavy industry. At the heart of every ESP system is the precipitator transformer — also known as an ESP transformer or transformer-rectifier (TR) set).
These specialised transformers supply the high-voltage power required for electrostatic precipitation. An ESP transformer steps up the incoming AC supply and, together with a rectifier, delivers controlled high-voltage DC — often up to 100 kV — to the precipitator electrodes. This voltage charges airborne particles, allowing them to be collected on plates and removed from the flue gas stream.
At Reliable Transformers, our precipitator transformers are engineered for reliability, endurance, and precision in the toughest industrial environments. Designed for continuous operation under repeated short-circuit conditions, they perform dependably despite the frequent sparking and load fluctuations inherent to ESP applications.
Their robust insulation systems, efficient cooling, and rugged construction ensure long service life — even under harsh operating conditions. With a proven track record across South Africa’s coal-fired power stations and large industrial installations such as Sasol, our transformers have earned a reputation for unmatched reliability and performance.
Each unit can be custom-designed to match specific client requirements, with ratings optimised for different ESP systems, plant layouts, and environmental conditions.
