Zuverlässeg 220kV VV Traction Transformer fir Eisebunn Elektrifizéierungssystemer

Leading traction power: 220kV VV connected to single-phase traction transformer

On the main artery of modern electrified railways, stable and efficient power supply is the cornerstone of safe and high-speed train operation. Our 220kV VV single-phase traction transformer is a cutting-edge power equipment designed specifically for this core requirement. It is directly connected to the national high-voltage power grid, providing pure and reliable single-phase power for the railway traction power supply system.

Core technological advantage: VV connection, a robust choice

This product adopts the classic and mature VV connection method. This structure cleverly combines two single-phase transformer units internally, allowing them to directly extract two single-phase loads from a three-phase high-voltage power grid. Compared to other wiring methods, VV connected transformers have significant advantages such as compact structure, high material utilization, low operating losses, an einfach Ënnerhalt. It not only effectively balances the load of the three-phase power grid and reduces the negative sequence impact on the public network, but also becomes the preferred main transformer solution for electrified railways, especially heavy-duty and high-speed railway traction substations, with its inherent high reliability and economy.

Excellent performance to meet demanding challenges

We are well aware of the strict requirements for railway traction power supply. Dofir, this 220kV traction transformer is designed and manufactured to the highest standards:

• Héich Zouverlässegkeet: Using high-quality low loss silicon steel sheets and advanced winding structures, ensuring stable operation even under frequent load fluctuations and short-circuit impacts.
• Effizient an energiespuerend: Optimized magnetic and circuit design significantly reduces no-load and load losses, resulting in lower operating costs throughout the entire lifecycle.
• Strong short-circuit resistance: The winding has undergone strict dynamic and thermal stability calculations and reinforcement processes, and has excellent short-circuit withstand capability.
• Environmentally friendly and low-noise: Emphasize the use of environmentally friendly materials and adopt multiple noise reduction technologies, resulting in low operating noise and environmental friendliness.
• Intelligent monitoring: It can integrate an intelligent online monitoring system to monitor key parameters such as oil temperature, Ueleg Niveau, gass, and load in real time, achieving status warning and intelligent operation and maintenance.
