Advantages
Ultimate protection and weather resistance
With IP56-level fully sealed protection combined with triple anti-corrosion technology of titanium alloy/sacrificial anode/special coating, it achieves long-term salt spray corrosion resistance underwater and stable operation in a wide temperature range of -30 ° C to +40 ° C, ensuring the reliability of the ship's power system in extreme Marine environments and over 20 years of maintenance-free life.
Safety, reliability and structural innovation
The IP56-level protection is achieved through epoxy resin casting and titanium alloy sealing. Combined with the three-dimensional wound core short-circuit resistance structure (cold-rolled silicon steel sheet stacking) and electromagnetic shielding design, it ensures insulation stability in salt spray and water immersion environments (power supply is restored within 2 hours after 48 hours of water immersion). Meanwhile, the embedded optical fiber sensor + electromagnetic damper can counteract 90% of the vibration. The amplitude is reduced to 0.02mm under 12-level wind and waves.
High energy efficiency and intelligent operation and maintenance
With low-loss three-dimensional core and bionic porous heat dissipation + phase change material, the no-load loss is 20%-30% lower than the traditional oil-immersed type, and the noise is < 43dB(A); Combined with quantum machine learning algorithms (trained with 10 billion fault samples, false alarm rate < 0.001%) to warn insulation deterioration 180 days in advance, the metal bellows oil storage tank is designed to be maintenance-free, reducing operation and maintenance costs throughout its life cycle by 30%.
