The Dry Type Marine Transformer from Evernew Transformer is engineered to meet the demanding requirements of the marine and offshore industries. With a focus on safety, efficiency, and environmental protection, this transformer is designed to provide reliable electrical isolation, voltage step-down, and robust performance in harsh conditions. Unlike traditional oil-filled transformers, the Dry Type Marine Transformer eliminates the risks associated with oil leakage and fire hazards, making it an environmentally friendly solution for power distribution on ships, offshore platforms, and coastal facilities.

This transformer boasts an oil-free design, which not only enhances safety but also offers superior thermal performance and noise reduction. Engineered to withstand the corrosive effects of salt mist, high humidity, and mechanical vibrations, the Dry Type Marine Transformer is the ideal choice for applications in extreme environments. Whether used for power, lighting, or isolation, this transformer is built for long-lasting, maintenance-free operation.

Marine Transformer Key Features:

Modular Cabinet Design:
- The modular design of the transformer cabinet allows for quick and easy assembly, disassembly, and installation. This modular approach makes maintenance more convenient and minimizes downtime, especially when servicing transformers in remote or offshore locations.
Noise Reduction Technology:
- The transformer features a through-hole screw design and carefully designed components to reduce operational noise to a minimum. This feature is essential for environments where noise control is crucial, such as offshore platforms and ships where noise pollution can impact sensitive operations.
Superior Durability and Protection:
- The coil windings are vacuum-impregnated with high-quality resin, enhancing their anti-corrosion, anti-fungal, and anti-moisture properties. This is essential for preventing degradation in the challenging marine environment.
- The transformer is constructed with high quality cold rolled silicon steel and undergoes 45° angle inspections for the core material, which improves magnetic properties, minimizes energy loss, and enhances efficiency.
- Salt mist resistance: The transformer’s construction includes special coatings to protect against salt mist, a common challenge in marine applications, ensuring a longer service life and reliable performance.
High Vibration Resistance:
- Designed to withstand extreme mechanical stress and vibration, the Dry Type Marine Transformer is ideal for offshore platforms and vessels that experience dynamic movement. It ensures that the transformer continues to function properly even in high-vibration environments.
Customizable Power and Voltage Ratings:
- Available in power ratings ranging from 250 KVA to 9000 KVA, this transformer is customizable to meet specific voltage requirements. The ability to adjust voltage and power ratings makes this transformer adaptable to a wide range of applications, from small vessels to large offshore platforms.
Efficient Cooling System:
- The self-cooling (air-cooled) design provides superior heat dissipation, even during peak load conditions. This feature ensures that the transformer operates efficiently, reducing the risk of overheating and improving energy efficiency.
