20kVA 100kVA 1000kVA High Frequency Cast Resin Toroidal Power Dry Type Transformer

Common design: All adopt ring-shaped iron cores (formed by winding high magnetic conductivity silicon steel sheets, with a closed magnetic circuit and low leakage flux). The windings are tightly wound around the iron core and are solidified by high-frequency resin vacuum casting, forming a fully sealed insulation structure. It has moisture-proof, dust-proof, and temperature-resistant (F class / H class) properties. The high-frequency adaptability is strong, enabling stable operation in high-frequency power grids, with high conversion efficiency (low no-load loss) and low noise.
Capacity differences and applications:
20 kVA: Compact in size, suitable for small power scenarios such as small precision equipment, medical instruments, and laboratory power supplies, providing stable low-voltage power supply.
100 kVA: Medium capacity, suitable for commercial building local distribution, industrial small production lines, and edge devices in data centers, balancing power and space requirements.
1000 kVA: Large capacity design, used for industrial high-power equipment, new energy inverters, and large precision production lines, supporting high-load high-frequency power consumption demands.
