Introducing CEEG's remarkable AFWF Marine Transformer, a testament to advanced engineering with its dual cooling methods: self-cooled (AN) and fan-cooled (AF). Our premium AFWF transformers, including cutting-edge 12-pulse and 24-pulse rectifier models, are expertly crafted for diverse applications. Whether it's for power supply, lighting, isolation, propulsion, or rectification within power grids, these versatile transformers ensure unparalleled efficiency and reliability.
Our transformers are meticulously designed with insulation classes B, F, and H to suit various maritime needs. For low-voltage vessel or ship transformers (under 1kV), we offer capacities up to an impressive 8000kVA. Likewise, our medium-voltage vessel and offshore platform transformers (below 10kV) also support up to 8000kVA, ensuring robust power distribution. We pride ourselves on custom designs tailored to specific specifications, backed by certifications from prestigious classification societies such as CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and others, guaranteeing the highest quality and safety standards in the industry.
What makes the AFWF transformer a standout choice for marine applications? The CEEG marine water-cooled transformer, an innovation for large vessels, comes with two distinct cabinets: the transformer cabinet and the cooling system cabinet. Strategically positioned fans efficiently transfer heat from the transformer cabinet to the cooling system cabinet, circulating cooled air back to maintain optimal safety. This sophisticated system expels heat through circulating water, protecting other equipment and ensuring a steady temperature. Our state-of-the-art cooling system comprises main and auxiliary components including fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks.
Unveil the Key Features of the Marine Transformer
Unmatched Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core surface is expertly treated with a special resin coating, ensuring durability and longevity.
Unrivaled Efficiency and Durability: Our transformers feature exceptionally low losses, minimal partial discharge, strong overload capacity, and reduced noise levels. This is achieved through the use of high-quality, highly permeable grain-oriented cold-rolled silicon steel sheets with a precise thickness of 0.18-0.3mm, along with a through-bolt structure to effectively reduce noise.
Enhanced Performance through Cutting-Edge Techniques: Coils are subjected to multiple varnish dips, while electrical and mechanical connections utilize specialized processes to enhance performance.
Seismically Resilient: The silicon steel core incorporates a 45° fully oblique step joint and square tube draw plate structure, bound with insulating tape, offering exceptional earthquake resistance, flame retardance, and high-level insulation.
Effortless Installation with Modular Design: The cabinet's innovative modular design facilitates quick and hassle-free installation.
Designed for Ultimate Flexibility: Our custom designs cater to specific requirements, offering flexible design solutions and rapid response to your needs.
For cable management, the transformer's enclosure is equipped with a convenient stuffing box on either the left or right side. For transformers with capacities of 500kVA and above, the default configuration is bottom entry and exit, with strategically placed cable holes on the transformer base to ensure secure and scratch-free cable handling.
Explore the Operating Conditions Operational within an ambient temperature range of -25°C to 45°C, our transformers are designed to withstand extreme environments. With a relative humidity threshold of ≤ 95%, our transformers are built to endure high moisture conditions. Engineered to perform with a ship's swinging angle of ≤ 22.5° and a tilt angle of ≤ 15°, ensuring stability and safety at sea. Operational conditions include exposure to condensation, oil mist, salt spray, and mold, withstanding the toughest maritime environments. Our transformers are meticulously crafted to endure vibrations and impacts, ensuring long-lasting reliability in dynamic conditions.
