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.
