Intermediate Transformer Units for Renewable Energy Applications
Integrating a transformer and a ring main unit (RMU), Kitashiba’s intermediate transformers feature a small footprint and a short installation period. Intermediate transformers efficiently supply energy from renewable power generation systems.
Characteristics
1
Small footprint
- Compact transformers integrating an RMU
Foundation area: 66% less than Kitashiba’s previous model - Three-winding (two-circuit) transformer
Number of transformers required: Two 500kVA two-winding transformers → One 1,000kVA three-winding transformer
2
Short installation period
- The unified design helps reduce the installation period significantly because it simplifies foundation, installation, and cable-laying work, as well as testing.
- Kitashiba’s intermediate transformers provide enhanced product reliability because they are assembled at the factory.
3
Environmentally friendly
- Kitashiba also offers rapeseed oil-immersed transformers ideal for renewable energy applications.
