ZBW-12/0.4 Railway Power Remote Control Box-type Transformer

This product combines two independent power supply units—self-resetting and through-type—within a single enclosure. They are electrically isolated, ensuring safety, reliability, and minimal external interference, while offering a full range of functions. The technology is leading in China. It can automatically disconnect faults in the 10kV line by utilizing the relationship between time and voltage, and enables remote control, signaling, and monitoring of the station's power supply by the dispatch center. It is a key component in railway automatic block systems and power-through lines.
