35kV S11/SZ11 Series Oil-Immersed Power Transformers
These series feature an optimized core and winding structure using high-grade cold-rolled silicon steel and oxygen-free copper windings, reducing no-load and load losses by over 25% compared to standard models.
Advanced Construction:
The laminated iron core is manufactured from high-quality grain-oriented silicon steel, minimizing core vibration and no-load losses. Reinforced internal supports prevent buckling deformation under electromagnetic stress, significantly improving short-circuit withstand capability.
Primary Applications:
| Rated Capacity (KVA) | Rated Voltage (KV) | Connection Symbol | Short-circuit Impedance (%) | No-Load Losses (W) | Load Losses (W) | Dimensions (LxWxH, mm) | |
