CEEG proudly presents the AFWF Marine Transformer, a marvel of engineering featuring dual cooling methods: natural self-cooling (AN) and enhanced fan-assisted cooling (AF). Our collection includes premium AFWF transformers alongside specialized 12-pulse and 24-pulse rectifier transformers, catering to a myriad of applications. These adaptable transformers excel in power supply, lighting, isolation, propulsion, and rectification within complex power grid systems.
Our top-of-the-line transformers are available in insulation classes B, F, and H, ensuring maximum performance. For low-voltage vessel/ship transformers (sub-1kV voltage levels), we offer impressive capacities up to 8000kVA. The same remarkable capacity extends to our medium-voltage vessel/ship and offshore platform transformers (sub-10kV voltage levels). We pride ourselves on bespoke designs crafted to meet exacting specifications, backed by certifications from globally respected classification societies like CCS, ABS, BV, DNVGL, LR, KR, NK, RINA, among others.
How does the AFWF transformer operate and deliver its cooling efficiency? The CEEG marine water-cooled transformer, crafted for large maritime vessels, comprises two integral cabinets: one for the transformer and the other for the sophisticated cooling system. High-performance fans seamlessly transfer heated air from the transformer cabinet to the cooling system cabinet, recirculating refreshing cool air to guarantee optimal operational safety. Heat dissipated by the transformer is efficiently expelled from the ship via circulating water within the water-cooled system, preserving the integrity of other onboard equipment and stabilizing cabinet temperatures. Its cutting-edge cooling system is equipped with primary and auxiliary components, including fans, water-cooling units, air ducts, leak alarms, temperature controllers, and water tanks, ensuring peak performance and reliability.
Key Features of the Marine Transformer: A Maritime Game-Changer
Outstanding Resistance: Engineered to resist moisture, salt spray, mold, and rust, the iron core surface is fortified with a specialized resin coating, ensuring longevity and durability even in the harshest marine environments.
Unmatched Efficiency and Longevity: Experience low operational losses, negligible partial discharge, robust overload capacity, and whisper-quiet operation. This is achieved with premium, highly permeable grain-oriented cold-rolled silicon steel sheets, measuring a sleek 0.18-0.3mm in thickness. The through-bolt structure further minimizes noise to create a product of superior efficiency.
Superior Performance with Cutting-Edge Techniques: Our coils undergo meticulous multiple varnish dipping processes, and both electrical and mechanical connections benefit from advanced, specialized techniques for enhanced performance.
Earthquake-Ready Resilience: Featuring a silicon steel core with a 45° fully oblique step joint and square tube draw plate structure, bound with insulating tape, our transformers promise earthquake resistance, flame retardancy, and superior insulation standards.
Effortless Installation: Thanks to the cabinet's intuitive modular design, installation is both swift and effortless, facilitating a smooth setup experience.
Designed for Flexibility: We offer custom designs that cater to your unique specifications, promising flexible options and rapid responses to meet your needs.
Practical Cable Management: The transformer's enclosure is equipped with a convenient stuffing box for seamless cable entry and exit, positioned on either the left or right side. For transformers with capacities of 500kVA and above, the standard is bottom entry and exit, with thoughtfully designed cable holes in the transformer base ensuring secure, scratch-free cable management.
Operating Conditions: Delivering Excellence in Any Environment Ambient Temperature Range: Designed to perform within a wide range from -25°C to 45°C, ensuring reliability across diverse maritime conditions. Moisture Handling: Relative humidity tolerance up to an impressive 95%, safeguarding functionality even in highly humid environments. Stability in Motion: Capable of enduring ship's swinging angles of up to 22.5° and tilt angles up to 15°, promising stability and reliability. Rugged Operation: Engineered to thrive amidst condensation, oil mist, salt spray, and mold, ensuring resilient operation in challenging maritime conditions. Vibration and Impact Resistance: Meticulously designed to withstand the rigors of vibrations and impacts, guaranteeing dependable performance at sea.
