CEEG's AFWF Marine Transformer is a marvel of engineering, featuring dual cooling methods: self-cooled (AN) and fan-cooled (AF). These top-tier AFWF transformers, along with our specialized 12-pulse and 24-pulse rectifier models, are the epitome of versatility. Perfectly suited for power supply, lighting, isolation, propulsion, and rectification within power grids, these transformers ensure superior performance and reliability in demanding marine environments.
Our transformers are available with insulation classes B, F, and H, catering to a wide range of applications. For low-voltage vessel/ship transformers (below 1kV), we offer capacities up to an impressive 8000kVA. Our medium-voltage vessel/ship and offshore platform transformers (below 10kV) also support capacities up to 8000kVA. We excel in custom designs tailored to specific needs, backed by certifications from renowned classification societies such as CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and more, ensuring unparalleled quality and compliance.
How does the AFWF transformer function?
The CEEG marine water-cooled transformer, engineered for large vessels, comprises two distinct cabinets: the transformer cabinet and the cooling system cabinet. Efficient fans transfer hot air from the transformer cabinet to the cooling system cabinet, where it is cooled and recirculated, maintaining operational safety. Heat generated is expelled from the ship via circulating water in the cooling equipment, safeguarding other equipment and ensuring stable cabinet temperatures. The advanced cooling system includes an array of components such as fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks, providing robust and efficient cooling.
Key Features of the Marine Transformer
Exceptional Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core surface is treated with a specialized resin coating, offering unmatched protection.
Superior Efficiency and Durability: With low losses, minimal partial discharge, strong overload capacity, and low noise, these transformers are built to last. This is achieved using premium, highly permeable grain-oriented cold-rolled silicon steel sheets, with thicknesses ranging from 0.18-0.3mm, combined with a through-bolt structure to further minimize noise.
Enhanced Performance with Advanced Techniques: Coils undergo multiple varnish dips, and all electrical and mechanical connections utilize specialized processes to ensure peak performance and reliability.
Seismic Resilience: The silicon steel core employs a 45° fully oblique step joint and square tube draw plate structure, bound with insulating tape. This design ensures earthquake resistance, flame retardance, and high insulation performance, providing robust protection under extreme conditions.
Effortless Installation: The cabinet's modular design allows for quick and easy installation, minimizing downtime and enhancing operational efficiency.
Tailored for Flexibility: Our custom designs are crafted to meet specific requirements, offering flexible design options and prompt responses to fulfill every unique need.
For cable entry and exit, the transformer's enclosure features a convenient stuffing box located on either the left or right side. For transformers with capacities of 500kVA and above, the standard method is bottom entry and exit, with cable holes on the transformer base to ensure secure and scratch-free cable handling, ensuring a safe and efficient setup.
Operating Conditions Ambient temperature range: -25°C to 45°C, ensuring reliability in extreme conditions. Relative humidity: ≤ 95%, suitable for marine environments. Ship's swinging angle: ≤ 22.5°, tilt angle: ≤ 15°, accommodating the dynamic conditions at sea. Operational conditions encompass condensation, oil mist, salt spray, and mold, providing robust and reliable performance in challenging environments. Transformers designed to withstand vibrations and impacts, ensuring durability and longevity even in the harshest marine conditions.
