Models: SBH21-MRL-100/10, SBH21-MRL-200/10, SBH21-MRL-400/10, SBH21-MRL-630/10
Introduction: The core columns and high- and low-voltage coils of the amorphous alloy three-dimensional wound core are circular. Circular coils experience uniform stress when subjected to sudden short circuits, effectively resisting radial forces. The three-phase magnetic circuit is completely symmetrical and equal in length, ensuring power supply balance, reducing magnetic reluctance, and lowering excitation current.
Features and Advantages: This transformer combines the three-dimensional wound core structure with low-loss amorphous alloy characteristics. It offers high core strength, strong short-circuit resistance, uniform temperature rise, low noise, and minimal magnetic leakage. It is ideal for urban residential areas with stringent noise requirements.
