Maritime transformers
Function
Three-phase marine transformers in enclosure are designed to supply control and lighting circuits in marine installations, where high reliability and resistance to harsh environmental conditions are required.
Three-phase marine transformers in enclosure are designed to supply control and lighting circuits in marine installations, where high reliability and resistance to harsh environmental conditions are required.
In the standard version, transformers are installed in a robust steel enclosure with protection degree IP23. The enclosure design allows quick disassembly and convenient access to winding taps, facilitating servicing and parameter adjustment. Supply cables are routed through the bottom, ensuring orderly installation and enhanced mechanical protection. The enclosures are powder-coated in RAL 7032 as standard; upon request, they can be manufactured in any color according to the individual requirements of the shipowner or project.
Benefits
- Enhanced operational safety in marine environments
- High resistance to harsh marine conditions, humidity, vibrations and salinity
- Increased reliability thanks to robust construction and appropriate IP protection degree
- Protection against overloads and short circuits, ensuring system stability
- Easy service access due to well-designed enclosure structure
Applications
- Marine industry – naval vessels, commercial ships, offshore units and onboard installations
Custom Design
Manufacturing a transformer with parameters other than those specified in the catalogue is possible upon prior consultation.
