Product Manufacturing Process

The manufacturing of China's cast resin dry core transformers involves a precise and controlled process to ensure optimal performance and safety. The core, generally made of high-grade silicon steel, is constructed to minimize losses and optimize efficiency. The windings are carefully prepared and encased in high-quality epoxy resin. This resin is vacuum cast, ensuring that there are no air bubbles, cracks, or inconsistencies, which might affect the transformer's performance. The vacuum casting method enhances mechanical strength and insulation, making it resistant to environmental contaminants. The cured resin forms a solid, compact structure, safeguarding the transformer against moisture, dust, and mechanical impacts. The combination of advanced materials and meticulous fabrication techniques ensures a reliable, durable, and efficient product.
