General technical characteristics and environmental adaptability

（1） Core technological advantages

Energy saving: The entire series of products adopt low loss design, and the iron core is made of high magnetic conductivity cold-rolled silicon steel sheets (amorphous alloy core series uses soft magnetic materials). The coil winding process is optimized, and the no-load loss and load loss are at the leading level in the industry. Long term operation can significantly reduce energy consumption costs.

Reliability: Key components (iron core, coil, oil tank, seals) have undergone strict selection and testing, with complete redundancy design, strong short-circuit resistance, excellent sealing performance (oil immersed products can effectively prevent oil leakage and oxidation), and long service life.

Compatibility: Parameters such as voltage level, connection group, and short-circuit impedance are compatible with mainstream global power grid standards, and can be used in conjunction with different brands of high and low voltage electrical equipment, with strong interchangeability.
