CEEG's innovative AFWF Marine Transformer is engineered for excellence, featuring dual cooling methods: self-cooled (AN) and fan-cooled (AF). We proudly offer an array of high-performance AFWF transformers, along with 12-pulse and 24-pulse rectifier transformers, among other sophisticated models. These adaptable transformers are impeccably suited for an array of applications including power supply, lighting, isolation, propulsion, and rectification within power grids, ensuring reliability and efficiency.
Our transformers are meticulously designed with insulation classes B, F, and H to cater to various requirements. For low-voltage vessel/ship transformers operating below 1kV, our equipment supports impressive capacities of up to 8000kVA. Similarly, our medium-voltage vessel/ship and offshore platform transformers, working below 10kV, also offer capacities reaching up to 8000kVA. We excel in creating bespoke designs tailored to your specific needs, backed by prestigious certifications from leading classification societies like CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, and more, assuring you of exceptional quality and compliance.
How does the AFWF transformer function? The CEEG marine water-cooled transformer is intelligently crafted for large vessels, comprising two separate cabinets: the transformer cabinet and the innovative cooling system cabinet. Efficient fans expertly channel hot air from the transformer cabinet to the cooling system cabinet, where it is cooled and recirculated to ensure safe and optimal operation. The heat generated by the transformer is effectively expelled from the ship using a sophisticated circulating water system, protecting other equipment and maintaining stable cabinet temperatures. The advanced cooling system is a marvel of engineering, featuring main and auxiliary components such as high-performance fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks, all working in harmony for superior safety.
Key Features of the Marine Transformer
Unmatched Resistance to Moisture, Salt Spray, Mold, and Rust: The iron core surface is expertly treated with a specialized resin coating, ensuring long-lasting durability.
Superior Efficiency and Enduring Durability: Our transformers boast lower losses, minimal partial discharge, exceptional overload capacity, and reduced noise levels. This is achieved using top-tier, highly permeable grain-oriented cold-rolled silicon steel sheets with a precise thickness range of 0.18-0.3mm, ingeniously combined with a through-bolt structure to significantly minimize noise, setting new standards in efficiency and durability.
Enhanced Performance through Cutting-Edge Techniques: Coils are meticulously processed with multiple varnish dips, and the electrical and mechanical connections are executed utilizing specialized techniques, ensuring robust performance and longevity.
Seismic Resilience for Ultimate Stability: The silicon steel core is innovatively designed with a 45° fully oblique step joint and a square tube draw plate structure, securely bound with insulating tape, providing unparalleled earthquake resistance, flame retardance, and high insulation characteristics.
Effortless Installation: The modular design of the cabinet promises swift and straightforward installation, reducing downtime and labor costs.
Tailored for Flexibility: We offer custom designs precisely aligned with specific requirements, delivering flexible design options and quick responses that cater to your unique needs and applications.
The transformer's enclosure is thoughtfully designed with a convenient stuffing box for cable entry and exit, positioned on either the left or right side to enhance accessibility. For transformers with capacities of 500kVA and above, the standard method is bottom entry and exit, complete with cable holes on the transformer base to ensure secure, scratch-proof cable handling, maximizing safety and operational efficiency.
Operating Conditions Our transformers operate optimally within an ambient temperature range of -25°C to 45°C, ensuring reliable performance in diverse environments. Relative humidity: Our products are designed to function flawlessly with a relative humidity of ≤ 95%, catering to various climatic conditions. Ship's swinging angle: Our transformers can withstand a swinging angle of ≤ 22.5°, with a tilt angle of ≤ 15°, ensuring stability and safety at sea. Our transformers are engineered to perform under various operational conditions, including condensation, oil mist, salt spray, and mold, guaranteeing longevity and reliability. These transformers are meticulously designed to endure vibrations and impacts, providing unmatched durability and performance even in challenging maritime environments.
