CDD Series Marine Transformer is used under normal conditions in ships, marine platforms, and other locations for lighting, power, communication, or electrical network isolation.
This series of marine transformer is suitable for voltages up to 750V, with frequencies of 50Hz and 60Hz, and single-phase capacities ranging from 0.05 to 10KVA. They are dry-type, self-cooling, and drip-proof transformers.
The marine transformer's core is of a core-type structure, made of high-quality cold-rolled silicon steel sheets, firmly securing the windings to minimize vibrations during operation. The coils are wound using high-quality, high-insulation grade enamel-coated or silk-covered wires with insulation classes of B, F, and H.
◆ Ambient temperature: -25 to +45°C.
◆ Relative humidity: not exceeding 95%.
◆ Influence of condensation, oil mist, salt spray, and mold.
◆ Vibration and impact generated during normal operation of the vessel.
◆ Roll angle of the ship during operation: ≤22.5°, tilt angle: ≤15°.
◆ The waveform of the power supply voltage is approximately sinusoidal, and the voltage supplied to the three-phase transformer is approximately symmetrical.
◆ Superior Insulation
The coils are wound with high-quality insulated wires or enamel wires using a spiral winding technique with ventilation ducts, allowing for better internal heat dissipation.
◆ High Voltage Transformer Coils
The coils are constructed using multiple layers of fiberglass mesh fillers, vacuum impregnated with epoxy resin, to significantly enhance electrical strength, improve short-circuit resistance, reduce partial discharge, provide flame retardancy, and enhance the "Three Protections" performance against moisture, salt spray, and mold.
◆ Core Selection
High-grade, low-loss silicon steel laminations are used for the core. The laminations are carefully stacked at a 45-degree angle in a seven-step-lap configuration, resulting in reduced magnetic leakage, low noise, low losses, and reduced mechanical vibrations.
