* Above specification may be changed to improve performance.
* Transformer of other specification than listed above can be made to order.
It incorporates a high-grade silicon steel core, energy-efficient low-loss windings, and a fully sealed heat dissipation structure—designs that yield minimal power consumption, low operational noise, and robust short-circuit withstand capacity. With an insulation level surpassing the LI950AC395 specification, it maintains stable operation in tough outdoor settings. Furthermore, it can be outfitted with real-time online monitoring and on-load voltage adjustment devices, which effectively safeguard the stable and efficient running of the power grid
