Electric Power Systems

Kitashiba offers optimal solutions.

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)

  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.

  

• Utility Transformers

  Solution

  • 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.

  

• 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.
