Rapeseed Oil-Immersed Transformers (ULTrans)
- Solution
-
- 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.

Intermediate Transformers
- Solution
-
- Integrated transformer and ring main unit (RMU)
- Small installation footprint and short installation period
- Efficiently supplies electricity from renewable power generation systems
A small footprint 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
- Solution
-
- Custom-designed (terminal arrangements, electrical connections, cooling method)
- High reliability
- Simplified maintenance and support
Kitashiba’s high-performance furnace transformers are optimized for low-voltage, high-current operation and are tailored to suit the specific needs of each customer, contributing to the development of the steel industry.
-
Instrument Voltage Current Transformers (VCTs)
- Solution
-
- 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.
-
Retrofilling
- Solution
-
- Quantitatively estimates the benefits of retrofilling for refreshing (i.e., prolonging the life) and increasing the capacity of transformers
- Development of a construction method for the management of mixed use of mineral and rapeseed oils
- Reduces the period of time required for retrofilling and parts replacement
Kitashiba offers a retrofilling service to increase the capacity of an aging transformer by replacing its insulating oil from mineral oil to rapeseed oil.
