Revolutionize your maritime power systems with CEEG's AFWF Marine Transformer, featuring innovative dual cooling methods: self-cooled (AN) and fan-cooled (AF). In addition to our top-of-the-line AFWF transformers, we also provide advanced 12-pulse and 24-pulse rectifier transformers, among various other models. These dynamic and adaptable transformers seamlessly integrate into applications such as power supply, lighting, isolation, propulsion, and rectification within sophisticated power grids.
Our cutting-edge transformers are equipped with insulation classes B, F, and H. For low-voltage vessel and ship transformers, with voltage levels below 1kV, we offer impressive capacities reaching up to 8000kVA. Similarly, our medium-voltage vessel, ship, and offshore platform transformers, with voltage levels below 10kV, support the same robust capacity of up to 8000kVA. We are experts in custom designs that cater to specific needs, and our products proudly hold certifications from prestigious classification societies such as CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and others, ensuring top-notch quality and reliability.
How does the AFWF transformer operate and enhance maritime efficiency? Experience cutting-edge marine technology with the CEEG marine water-cooled transformer, expertly engineered for large vessels. It features two specialized cabinets: the transformer cabinet and the cooling system cabinet. Efficient fans facilitate the transfer of hot air from the transformer cabinet to the cooling system cabinet, where the cooled air is recirculated, promoting safe operation. The transformer's generated heat is effectively expelled from the ship via circulating water in the water-cooled equipment, protecting other equipment and stabilizing cabinet temperatures. This state-of-the-art cooling system comprises main and auxiliary components like fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks.
Definitive Features of the Marine Transformer
Outstanding Resistance to Harsh Marine Environments: Expertly treated with a unique resin coating, the iron core surface endures moisture, salt spray, mold, and rust with exceptional resilience.
Unmatched Efficiency and Longevity: These transformers are engineered for low losses, reduced partial discharge, robust overload capacity, and minimal noise. This is achieved through the use of premium-grade, highly permeable grain-oriented cold-rolled silicon steel sheets with thicknesses ranging from 0.18-0.3mm, combined with a through-bolt structure that significantly reduces noise levels.
Enhanced Performance with Cutting-Edge Techniques: Coils are meticulously processed through multiple varnish dips, while electrical and mechanical connections are crafted using specialized advanced techniques, ensuring top-tier performance.
Earthquake Resilience: The silicon steel core is designed with a 45° fully oblique step joint and square tube draw plate structure, expertly bound with insulating tape to ensure resistance to seismic activities, flame retardance, and high insulation.
Seamless Installation: The transformer's cabinet features a modular design, offering swift and straightforward installation, saving time and effort.
Designed for Flexibility: Each transformer is custom-designed to meet specific requirements, providing flexible design solutions and ensuring prompt responsiveness to unique challenges.
For cable entry and exit, the transformer's enclosure includes a practical stuffing box located on either side. For transformers with capacities of 500kVA and above, the standard method is bottom entry and exit, with cable holes strategically placed on the transformer base to guarantee secure, scratch-proof cable management.
Operating Conditions Ambient temperature range: Experience optimal performance in conditions ranging from -25°C to 45°C. Relative humidity: Operates efficiently in environments with relative humidity levels of ≤ 95%. Ship's dynamic motion resilience: Designed to function seamlessly with a swinging angle of ≤ 22.5° and a tilt angle of ≤ 15°. Operational conditions: Our transformers are engineered to withstand the challenges of condensation, oil mist, salt spray, and mold, ensuring reliability in demanding maritime environments. Specifically designed to endure the vibrations and impacts associated with marine applications, our transformers offer unparalleled durability and reliability.
