* Above specification may be changed to improve performance.
* Transformer of other specification than listed above can be made to order.
It adopts a premium silicon steel core, energy-saving low-loss windings, and a hermetically sealed cooling system—features that translate to minimal power dissipation, reduced operational noise, and strong short-circuit tolerance. Boasting an insulation grade that surpasses the LI950AC395 standard, it maintains reliable performance even in harsh outdoor conditions. Additionally, it supports the integration of real-time online monitoring and on-load tap-changer devices, further securing the stable and efficient operation of the power grid.
