6.6KV Low Loss Fully Sealed Three-phase Low Loss Power Plant Distribution Transformer (S13-M Series)

Product advantage

- High voltage copper strip winding technology, improve lightning resistance

- Low voltage copper foil winding technology, high quality A class insulation material insulation
- Small magnetic leakage, high mechanical strength, strong resistance to short circuit
- The iron core is made of high quality cold-rolled grain oriented silicon steel sheet with mineral oxide insulation (from Baosteel and WISCO of China).
- By controlling the cutting and stacking process of silicon steel sheet, the loss level, no-load current and noise can be minimized
