SCB13-500/10.5 Dry-type Power Transformer

• Low Impedance – Stable Output, System Protection
  With short-circuit impedance of only 3.91%, it limits fault current while maintaining voltage stability. Sensitive equipment receives more reliable power, and downstream switchgear experiences lower short-circuit stress.
• Class H Insulation – High Temperature Tolerance, Long Life
  Maximum allowable temperature of 180°C with a 125K temperature rise limit. Even under long-term full load or short-term overload, the insulation system remains stable, significantly extending service life and reducing total lifecycle cost.
• Dyn11 Connection – Harmonic Suppression, Unbalanced Load Capability
  Provides a zero-sequence path for third harmonics, preventing harmonics from feeding back to the upstream grid. Allows 100% unbalanced load operation without derating. Ideal for commercial buildings, data centers, and factories with大量 single-phase or non-linear loads.
• Low Noise & Eco-Friendly – Suitable for Residential & Indoor Environments
  Optimized core and coil processes effectively reduce magnetostrictive noise. Operating noise below 55–60 dB(A) – significantly lower than traditional transformers. Oil-free, non-polluting, and recyclable, meeting green building and sustainability requirements.
• Compact & Durable – Easy Installation & Maintenance
  Total weight of only 1620 kg with a compact footprint. Standard IP20 protection with optional IP23/IP34/IP54 enclosures. Dry-type design requires no periodic oil changes or filtration – only routine cleaning, significantly reducing maintenance workload.
