CEEG's AFWF Marine Transformer boasts dual cooling methods: self-cooled (AN) and fan-cooled (AF). We also offer top-tier AFWF transformers, as well as 12-pulse and 24-pulse rectifier transformers, among other models. These versatile transformers are ideal for applications in power supply, lighting, isolation, propulsion, and rectification within power grids.
Our transformers come with insulation classes B, F, and H. For low-voltage vessel/ship transformers (voltage level below 1kV), capacities reach up to 8000kVA. Similarly, our medium-voltage vessel/ship and offshore platform transformers (voltage level below 10kV) also support capacities up to 8000kVA. We specialize in custom designs tailored to specific requirements, and our products come with certifications from esteemed classification societies including CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and more.
How does the AFWF transformer function? The CEEG marine water-cooled transformer, designed for large vessels, features two cabinets: the transformer cabinet and the cooling system cabinet. Efficient fans transfer hot air from the transformer cabinet to the cooling system cabinet, circulating cooled air back to ensure safe operation. The heat generated by the transformer is expelled from the ship through circulating water in the water-cooled equipment, safeguarding other equipment and maintaining stable cabinet temperatures. The advanced cooling system includes main and auxiliary components such as fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks.
Key Features of the Marine Transformer
Exceptional Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core surface is treated with a special resin coating.
Superior Efficiency and Durability: Featuring low losses, minimal partial discharge, strong overload capacity, and low noise. This is achieved using high-quality, highly permeable grain-oriented cold-rolled silicon steel sheets with a thickness of 0.18-0.3mm, coupled with a through-bolt structure to minimize noise.
Enhanced Performance with Advanced Techniques: Coils undergo multiple varnish dips, and electrical and mechanical connections utilize specialized processes.
Seismic Resilience: The silicon steel core employs a 45° fully oblique step joint and square tube draw plate structure, bound with insulating tape, ensuring earthquake resistance, flame retardance, and high insulation.
Effortless Installation: The cabinet's modular design allows for quick and easy installation.
Tailored for Flexibility: Custom designs to meet specific requirements, offering flexible design options and prompt responses.
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 default method is bottom entry and exit, with cable holes on the transformer base to ensure secure and scratch-proof cable handling.
Operating Conditions Ambient temperature range: -25°C to 45°C Relative humidity: ≤ 95% Ship's swinging angle: ≤ 22.5°, tilt angle: ≤ 15° Operational conditions encompass condensation, oil mist, salt spray, and mold. Transformers designed to withstand vibrations and impacts.
