Types of specialty transformer
Traction transformers
You see traction transformers in electric trains, high-speed railways, and urban transit systems. These transformers play a key role in moving people and goods quickly and safely. A traction transformer receives high-voltage AC power from the grid. It steps down the voltage to the level that train motors need. It also regulates and delivers power to the train’s propulsion system. You get reliable operation because the transformer includes protection and control features. Changzhou Guanghui’s traction transformers handle heavy loads and short-circuit impacts. You can trust them for use in busy rail networks and city transit lines.
Tip: Traction transformers help trains run smoothly, even when power demands change quickly.
Rectifier transformers
You use rectifier transformers when you need to change AC power into DC power. These transformers are important in factories, refineries, and renewable energy plants. For example, you find them in aluminum production, electrolysis, and battery charging stations. A rectifier transformer adjusts the voltage and supplies stable DC power for machines and processes. It helps reduce energy loss and keeps the voltage steady. Changzhou Guanghui offers rectifier transformers with a wide range of capacities. You can use them in both small and large industrial plants.
About 90% of aluminum plants use rectifier transformers for electrolysis.
Wind and solar power plants use more rectifier transformers each year to store energy and connect to the grid.
