用于船舶行业的变压器

The first electric propulsion applications were introduced in the late 1980s and subsequently developed with the implementation of static converters which helped to promote the concept. Nowadays electric propulsion with gas turbine or diesel engine driven power generation is used in hundreds of ships of various types and in a large variety of configurations. 

Azimuthing thrusters and podded thrust units, propulsion configurations for transit, maneuvering and station keeping have merged in several types of vessels in order to utilize installed thrust units for optimal transit, maneuvering and dynamic positioning.

Demanding installation requirements including reduced noise and vibration levels, limited space, special water cooled cooling system, and a high degree of security to avoid human risks, are some of the main reasons to choose Hitachi ABB Power Grids transformers.
