* Above specification may be changed to improve performance.
* Transformer of other specification than listed above can be made to order.
Focused on small and medium power distribution scenarios, it is suitable for 10-30kV medium-voltage systems with a power coverage range of 50-160kVA. It adopts oil-immersed cooling and a core made of high-magnetic-susceptibility silicon steel sheets; its low-loss design enables adaptation to light load fluctuations. With a compact box-type structure and an IP54 protection rating, it can be installed on outdoor bases without the need for a dedicated power distribution room. It is applicable to scenarios such as township power distribution networks, small-scale processing plants, and power supply for remote villages.
