Since its foundation in 1950, Nishishiba Electric Co., Ltd. has provided various power generation, industrial, and marine electrical systems for nearly 70 years, and their products and services have offered safety, security and convenience to customers and society.

In addition, Nishishiba's marine electrical systems, which enable safe and efficient navigation, are widely used in container vessels that carry goods around the world, LNG carriers that support energy security, and research vessels designed to carry out research at sea, ferryboats and other types of ships. Based on the technological development capabilities of the Toshiba Group, Nishishiba offers unique and sophisticated skills and capabilities as well as a wealth of expertise accumulated over the years. All these resources allow us to provide systems, component products and services that are high in quality, functionality and efficiency. A new rotary machinery factory has been completed in 2015. This will help us address customers' needs for today's large vessels and meet the growing demand for large-scale rotary machinery due to the increase in distributed power supplies. Nishishiba also offers high value-added and environmentally-friendly solutions that best fit electric propulsion ships and other types of ships.
Nishishiba continues to deliver solutions that meet the needs of customers in the social infrastructure sector, and contribute to the realization and development of a safe, secure and sustainable society together with its customers. Nishishiba is committed to leading the world as a provider of land and marine energy solutions.


High-voltage shaft driven generating system for ships

By using a transformerless direct online system to deliver electrical power through a direct high-voltage bus bar, have improved the energy efficiency of the shaft driven generating system and reduced the space required.

Large-scale generators for ships

In response to the recent increase in ship sizes, made model changes to the large-scale generators for ships. Through structural analysis, reduction of the size and weight of these new generators in comparison to conventional generators.


IEC standard-compliant switchgear NSG-Type A

Nishishiba has developed the high-voltage switchgear NSG-Type A, which is compliant with the International Electro technical Commission standards (IEC62271-200) and achieves the highest grade for safety.


Electric Vibration Balancer

An electric vibration balancer is an apparatus that suppresses vibrations in a ship's hull by counteracting the vibrations caused by the engine. By adopting a new system that controls the number of engine revolutions with an inverter, Nishishiba has been able to greatly reduce size and weight and also the amount of electricity consumed, in comparison to conventional models.
