500kV变压器是超高压输电网络的核心设备，承担电力系统骨干网架的电能转换与跨区域传输重任。其设计制造需满足严格的绝缘、散热及稳定性要求，以应对高电压、大电流的复杂工况。 
The 500kV transformer is a core component of ultra-high-voltage transmission networks, undertaking the critical tasks of power conversion and cross-regional transmission in the back-bone of the power system. Its design and manufacturing must meet stringent requirements for insulation, heat dissipation, and stability to address the complex conditions of high voltage and large current.
