Series Overview
SC(B) Series 10kV
Cast Resin Transformer
The SC(B) series is Ryan Transformers' flagship cast resin dry type transformer product line designed for 10kV medium-voltage distribution networks. All windings are vacuum-pressure encapsulated with Class F/Class H epoxy resin, providing exceptional resistance to humidity, pollution, and corrosive environments. As an oil-free design, it is inherently fire-safe and requires zero routine maintenance - the preferred choice for indoor substations worldwide.
With 20,000+ MVA annual production capacity across three Jiangsu production bases, and a 2023 joint venture partnership with Eaton, Ryan Transformers delivers consistent quality backed by global engineering expertise. We support GB, IEC, IEEE, DOE, BS, AS, NBR, and SS standards, covering virtually every market specification worldwide.
