Summary of Marine Single-Phase Waterproof Transformer:
The core of the waterproof autotransformer is constructed by laminating high-quality cold-rolled silicon steel sheets, ensuring high reliability, compact size, lightweight, and cost-effectiveness. The windings utilize high-performance, high-temperature-resistant composite insulating materials, combined with bobbin winding technology, offering strong electromagnetic resistance, neat craftsmanship, and an aesthetically pleasing appearance. Depending on the insulation class, the entire unit is impregnated with insulating varnish of corresponding grades, effectively reducing transformer noise, minimizing magnetic leakage, ensuring stable performance, and mitigating the impact of salt spray, mold, and other environmental factors. The windings are fully encapsulated, enabling prolonged underwater operation.
