Transformers
Kitashiba’s transformers are highly valued by many customers because Kitashiba employs a unique design technology, including cutting-edge design and analysis tools, manufacturing technology cultivated through our extensive experience and a stringent quality control system. Kitashiba’s transformers are utilized at power plants, substations, buildings, factories, and other facilities to provide stable electricity supply to workplaces and homes.
Rapeseed Oil-Immersed Transformers (ULTrans)
- Long life
- Low power loss
- Fully assembled transportation to reduce the on-site installation period
- Enhanced safety
- Reduction in environmental loads
The use of a natural ester vegetable oil (rapeseed oil) as an insulating oil improves environmental performance, prevents soil contamination, and improves safety. Additionally, the rapeseed oil-immersed ULTrans transformer provides long life and low power loss. ULTrans also reduces the on-site installation period because it is transportable while fully assembled.
Utility Transformers
- Cutting-edge basic design and 3D CAD-based production design
- Supports substations with increasingly higher voltage and capacity
- Small installation footprint, low power loss, and low noise
- Easy to maintain
While supporting substations with increasingly higher voltage and capacity, Kitashiba’s intermediate transformers satisfy various customer needs, including a small installation footprint, low power loss, low noise, and ease of maintenance. Intermediate transformers are utilized at various electricity supply facilities.
Integrated Transformer
- Integrated transformer and ring main unit (RMU)
- Small installation footprint and short installation period
- Efficiently supplies electricity from renewable power generation systems
otprint and a short installation period have been achieved by integrating the transformer with a ring main unit (RMU). Kitashiba’s intermediate transformers efficiently supply electricity from renewable power generation systems.
Furnace & Rectifier Transformers
- Custom-designed (terminal arrangements, electrical connections, cooling method)
- High reliability
- Simplified maintenance and support
Incorporating advanced design and manufacturing technologies, Kitashiba’s furnace and rectifier transformers provide high quality and long life. Kitashiba offers products that satisfy customers through a high level of dust control, outstanding drying technology, and stringent quality control.
Instrument Voltage Current Transformers (VCTs)
- Development of precision instrument technology
- Development of size and weight reduction technology
Comprised of an instrument voltage transformer (VT) and a current transformer (CT), VCTs transform high voltage and current to measurable levels. While being compact and lightweight, Kitashiba’s VCTs are capable of measuring power consumption with high precision.
