Q1: What is the main difference between oil-immersed transformers and cast resin dry-type transformers?
A: Dry-type transformers do not use flammable transformer oil, eliminating explosion and leakage risks. They are ideal for indoor installations, hospitals, and high-density commercial buildings requiring strict fire safety standards.
Q2: Can the SCB13 dry-type transformer be customized for high-voltage applications up to 35kV or 69kV?
A: Yes, we provide custom design and manufacturing for primary voltage levels including 11kV, 33kV, 35kV, and 69kV, matching your regional electrical grid frequency (50Hz or 60Hz) and vector group specifications.
Q3: What enclosure options are available for indoor/outdoor installation?
A: We offer standard IP00 (without enclosure for cabinet installation), IP20 (for indoor protection against solid objects), and IP23 (drip-proof enclosure for outdoor or harsh environments).
