Transformer for naval propulsion

Electrical propulsion systems have many advantages compared to conventional engine-driven propulsion systems. This technology naturally increases the demand for electrical propulsion on different vessels, such as cruise ships, container ships, and navy ships. Through technological advances and research, electrical propulsion systems are no longer limited to just small boats and vessels.

• Power: 7,5MVA
• Primary Voltage: 11kV, 60Hz
• Secondary Voltage: 2 x 1,8kV
• Cooling: air to water heat exchanger

Industrial converter transformers can be supplied from several kVA to many MVA. Gas Processing systems require large electrical pumps and compressors which are controlled by Transformer/ VSD systems.

Transformer for gas pumping station

• Power: 9MVA
• Primary Voltage: 33kV 50Hz
• Secondary Voltage: 6 x 2kV
• Cooling: air to air heat exchanger
• Weight: 51,700 lbs

Small hydro projects usually have faster environmental and licensing procedures. The equipment is usually in serial simplified production and the related civil works construction is reduced. The physically smaller size of equipment makes it easier to transport and install.

Example:

• Power: 1500/2000kVA
• Primary Voltage: 11kV
• Secondary Voltage: 0,69kV
• Frequency: 50Hz
• Protection: NEMA 3R
• Cooling: AAFA
• Weight: 11,000 lbs

Outdoor installations normally rely on oil-insulated transformers, even though environmental protection or easy maintenance demands the use of special dry type transformers.

• Power: 2000kVA
• Primary Voltage: 11kV
• Secondary Voltage: 0,433kV
• Frequency: 50Hz
• Outdoor Protection: NEMA 12
• Cooling: AA
• Weight: 14,300 lbs

Many electric engines are found on vessels. Such motors are generally powered using VSD and custom converter transformers. Drills, thrusters, compressors, pumps, etc. are typically configured as described.

EXAMPLE:

• Power: 3,5MVA
• Primary Voltage: 6,6kV 60 Hz
• Secondary Voltage: 2x0,715kV
• Frequency: 60Hz
• Cooling: air to water heat exchanger
• Weight: 14,740 lbs

MV transformers are almost always present on board of vessels, in particular on cruise ships.

• Power: 4MVA
• Primary Voltage: 0,6kV
• Secondary Voltage: 0,690kV
• Frequency: 50/60Hz
• Cooling: AA
• Weight: 17,600 lbs

The infrastructure sector has many uses for electric motors.

One example is transformers, through which electricity is pumped into residential complexes.
