Introducing the CEEG AFWF Marine Transformer, a marvel of engineering that delivers unparalleled performance with its dual cooling techniques-self-cooled (AN) and fan-cooled (AF). Our collection also includes elite AFWF transformers and advanced 12-pulse and 24-pulse rectifier transformers. These exceptional transformers are perfectly suited for a wide array of applications including power supply, lighting, isolation, propulsion, and rectification within dynamic power grids.
Our transformers are crafted with precision, featuring insulation classes B, F, and H. For low-voltage vessel/ship transformers (voltage level below 1kV), they offer remarkable capacity up to 8000kVA. Similarly, our medium-voltage vessel/ship and offshore platform transformers (voltage level below 10kV) support capacities up to 8000kVA as well. We excel in bespoke designs tailored to meet unique specifications, and our products bear prestigious certifications from renowned classification societies such as CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and many others.
How does the AFWF transformer function? The CEEG marine water-cooled transformer, expertly crafted for large-scale vessels, features an ingenious design with two separate cabinets: the transformer cabinet and the cooling system cabinet. Highly efficient fans meticulously channel hot air from the transformer cabinet to the cooling system cabinet, with cooled air recirculated to sustain optimal conditions. The generated heat is effectively expelled from the ship through the water-cooling system, ensuring the safety of other equipment and maintaining stable temperatures. The sophisticated cooling system boasts primary and auxiliary components, including fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks, ensuring operational excellence.
Key Features of the Marine Transformer
Exceptional Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core surface is meticulously treated with a specialized resin coating, providing superior protection against harsh marine conditions.
Unmatched Efficiency and Durability: Engineered with low losses, minimal partial discharge, formidable overload capacity, and reduced noise. This superior performance stems from the use of premium, highly permeable grain-oriented cold-rolled silicon steel sheets, ranging from 0.18-0.3mm in thickness, combined with a through-bolt structure to significantly diminish noise levels.
Enhanced Performance with Advanced Techniques: Coils are expertly subjected to multiple varnish dips, with electrical and mechanical connections executed using state-of-the-art processes for elevated performance and reliability.
Seismic Resilience: The silicon steel core is ingeniously designed with a 45° fully oblique step joint and square tube draw plate structure, securely bound with insulating tape, offering robust earthquake resistance, flame retardance, and high insulation.
Seamless Installation: Our cabinet's modular design ensures swift and straightforward installation, minimizing downtime and maximizing efficiency.
Tailored for Flexibility: We offer custom designs to cater to specific needs, presenting flexible design options and ensuring prompt and responsive service.
For cable management, the transformer's enclosure is equipped with a thoughtfully designed stuffing box positioned on either the left or right side. For transformers with capacities exceeding 500kVA, the standard approach is bottom entry and exit, with cable holes strategically placed on the transformer base to guarantee secure and scratch-proof handling.
Operating Conditions Ambient temperature range: -25°C to 45°C, ensuring reliable performance across various climates. Relative humidity: ≤ 95%, engineered to perform in high moisture environments. Ship's swinging angle: ≤ 22.5°, tilt angle: ≤ 15°, designed to operate smoothly amidst marine motion. Operational conditions encompass challenges like condensation, oil mist, salt spray, and mold, withstanding severe marine environments. Our transformers are crafted to endure vibrations and impacts, ensuring robustness and reliability in challenging conditions.
