CSD Marine Dry-Type Transformer: Advanced Power Conversion for Modern Vessel Electrification
Introduction to CSD Marine Transformers
The CSD marine dry-type isolation transformer is engineered for 50-60Hz AC circuits, delivering reliable power distribution across marine electrical systems, port shore power conversion, new energy vessels, and industrial applications—including precision machinery control systems and marine safety lighting. Certified by CCS and compliant with international marine engineering standards, these transformers maintain operational stability in high-humidity, high-vibration, and dynamic tilt conditions (up to 22.4° roll and 15° pitch).
Core Technological Features
- High-Efficiency Magnetic Core: Utilizes amorphous alloy and cold-rolled silicon steel laminations for reduced core loss and optimized energy efficiency.
- Low Harmonic Distortion: Dyn11 vector group configuration combined with sine-wave filtering limits total harmonic distortion (THD) to under 2%, ensuring clean power output.
- Multi-Voltage Compatibility: Supports flexible voltage transformation for 440V, 660V, and 690V systems.
- Robust Enclosure & Cooling: IP56-rated housing with PTC thermistor temperature monitoring and forced-air cooling for thermal management in confined marine spaces.
- Wide Voltage Tolerance: Features ±10% input voltage adaptability, enhancing performance under fluctuating supply conditions.
- Advanced Insulation System: Vacuum pressure impregnation (VPI) with glass-reinforced epoxy resin encapsulation offers moisture, corrosion, and partial discharge resistance.
- Renewable & Hybrid Ready: Compatible with photovoltaic and fuel cell bidirectional energy flow, suitable for medium-voltage propulsion and LNG-powered vessels.
