The traction transformer is a highly specialized core equipment designed exclusively for electrified railways (high-speed rail, bullet trains, standard rail) and urban transit systems (subway, light rail). Traction transformers deliver stable power conversion under complex line operating conditions, and its primary function is to step down high-voltage grid power (110kV/220kV) to the precise voltage required by electric locomotives (27.5kV/55kV). Beyond voltage conversion, the traction power transformer achieves critical electrical isolation, phase transformation, and dynamic three-phase grid load balancing. Built to endure extreme, frequent short-circuit impacts and massive short-term overloads, it is the beating heart of modern transportation infrastructure.

Core Parameters:

• Rated Capacity: 10MVA ~ 63MVA (Supports 1.5x~2.0x short-term massive overload).

• Voltage Configuration: Grid side 110kV/220kV stepped down to Traction side 27.5kV/55kV.

• Special Vector Groups: V/v, Scott, YNvd, YNd11 optimized for transit load balancing.

The rectifier transformer is a heavy-duty special transformer engineered specifically to supply power to rectifying equipment (thyristors, diodes). Its primary function is to transform high or medium AC grid voltage into the precise AC voltage required by rectifier circuits to produce stable DC power. As a typical high voltage rectifier transformer, it achieves vital galvanic isolation, suppresses harmonic pollution via multi-pulse phase shifting, and aggressively resists DC bias saturation. Tailored for rigorous industrial operating conditions, the rectifier duty transformer is the indispensable power source for electrolysis, electroplating, massive DC drives, and high-power charging systems.

Core Parameters:

• Rated Capacity: 100kVA ~ 100MVA (Built to endure 1.2x~1.5x severe load impacts).

• Voltage Configuration: Grid side 10kV/35kV stepped down to precise operational LV (tens to hundreds of Volts).

• Special Vector Groups: Phase-shifting designs (e.g., 12-pulse, 24-pulse) for harmonic elimination.
