CEEG's cutting-edge AFWF Marine Transformer is engineered with dual cooling capabilities: self-cooled (AN) and fan-cooled (AF). We deliver premium-quality AFWF transformers alongside 12-pulse and 24-pulse rectifier transformers, among other exceptional models. These adaptable transformers are perfectly suited for diverse applications, including power supply, lighting, isolation, propulsion, and rectification within power grids, ensuring optimal performance and reliability.
Our transformers are available in insulation classes B, F, and H. For low-voltage vessel/ship transformers (voltage level below 1kV), they offer remarkable capacities reaching up to 8000kVA. Similarly, our medium-voltage vessel/ship and offshore platform transformers (voltage level below 10kV) support impressive capacities up to 8000kVA. We specialize in bespoke designs tailored to meet your specific requirements. Our products are certified by prestigious classification societies, including CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and many more, ensuring the highest standards of quality and safety.
How does the AFWF transformer function? Discover the sophisticated mechanisms behind CEEG's AFWF transformer, designed to deliver unparalleled performance and reliability. The CEEG marine water-cooled transformer is meticulously crafted for large vessels, featuring two distinct cabinets: the transformer cabinet and the cooling system cabinet. Efficient fans seamlessly transfer hot air from the transformer cabinet to the cooling system cabinet, where cooled air is recirculated to ensure safe and stable operation. The heat generated by the transformer is efficiently expelled from the ship through circulating water in the water-cooled system, safeguarding other equipment and maintaining optimal cabinet temperatures. This advanced cooling system comprises main and auxiliary components such as fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks, ensuring comprehensive protection and efficiency.
Key Features of the Marine Transformer
Exceptional Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core is meticulously treated with a special resin coating, providing unparalleled protection and longevity.
Superior Efficiency and Durability: With low losses, minimal partial discharge, robust overload capacity, and low noise, these transformers employ high-quality, highly permeable grain-oriented cold-rolled silicon steel sheets with thicknesses of 0.18-0.3mm. A through-bolt structure is used to minimize noise, ensuring a quiet and efficient operation.
Enhanced Performance with Advanced Techniques: Coils undergo multiple varnish dips, while electrical and mechanical connections are executed using specialized processes for improved reliability and performance.
Seismic Resilience: The silicon steel core boasts a 45° fully oblique step joint and square tube draw plate structure, bound with insulating tape, guaranteeing earthquake resistance, flame retardance, and high insulation for ultimate safety and durability.
Effortless Installation: The cabinet's modular design ensures quick and easy installation, offering convenience and efficiency.
Tailored for Flexibility: Custom designs cater to specific requirements, offering flexible design options and prompt, responsive service to meet the unique needs of our customers.
For cable entry and exit, the transformer's enclosure is equipped with a convenient stuffing box located on either the left or right side. For transformers with capacities of 500kVA and above, the default method is bottom entry and exit, with cable holes on the transformer base ensuring secure and scratch-proof cable handling, providing peace of mind during installation and operation.
Operating Conditions Ambient temperature range: -25°C to 45°C, offering adaptability to a wide range of environmental conditions. Relative humidity: ≤ 95%, ensuring reliable performance even in high humidity environments. Ship's swinging angle: ≤ 22.5°, tilt angle: ≤ 15°, designed for stability and performance amidst the dynamic conditions of marine environments. Operational conditions encompass condensation, oil mist, salt spray, and mold, ensuring robust and reliable performance in challenging marine environments. Transformers are meticulously designed to withstand vibrations and impacts, offering unparalleled durability and reliability in the demanding marine environment.
