33kv Power Supply Transformer S11 Transformer Oil Filled 12500kVA High Voltage/Medium Voltage Transformers

Crafted with imported premium cold-rolled silicon steel sheets, the transformer core minimizes no-load loss and current. Tight binding ensures compactness and noise reduction.

High/low voltage windings use oxygen-free copper: low-voltage ones ≤500kVA adopt double-layer cylinder structure, while ≥630kVA use double/four helix structure; high-voltage windings feature multi-layer cylinder structure.

Wired in Dyn11 connection group, it mitigates grid harmonic interference and boosts power supply quality.

Boasting a fully sealed structure, its inner and outer surfaces are coated with three primers and one finish, delivering salt-fog, moisture and fungus resistance for attractive, durable and reliable performance.

With measured noise below standard, it requires no maintenance under normal operation.
