Dry-type Transformer

SCB2500kVA2

Category: Dry-type Transformer

Dry-type transformer adopts air cooling medium with epoxy resin insulation. It features fire resistance, maintenance-free and pollution-free characteristics. Safe and reliable, widely used in indoor, densely populated distribution projects with strict fire safety requirements.
  1. Safe & eco-friendly, non-flammable: No insulating oil, zero risk of oil leakage, fire or explosion with outstanding fire resistance.
  2. Low maintenance: No oil sampling or oil replacement required, less routine inspection work.
  3. Compact structure: Suitable for indoor installation and can be placed near load centers.
  4. Moisture & dust resistance: Epoxy cast type withstand condensation, applicable in humid and dusty environments.
  5. Low noise: Quiet operation, ideal for noise-sensitive areas such as residential buildings.
  6. Notes: Higher purchasing cost than oil-immersed transformers at the same kVA rating; limited heat dissipation for large capacity and weaker overload capability.
