13.8 KV Distribution Transformer advantage

---

-High voltage copper wire winding technology to improve lightning resistance performance

-Low voltage foil winding technology, high-quality A-E grade insulation material insulation

-Low magnetic leakage, high mechanical strength, and strong short-circuit resistance

-The material of the iron core is high-quality cold-rolled grain oriented silicon steel sheets with mineral oxide insulation (from Baosteel and Wuhan Iron and Steel Group in China)

-By controlling the process of cutting and stacking silicon steel sheets, the loss level, no-load current, and noise are minimized
