In the national energy saving and environmental protection policy support, amorphous alloy transform-er has been widely used in the field of power distribution. With the continuous improvement of thetechnical level, the new show in the power distribution field – amorphous alloy three-dimensional rollediron core transformer technology is developing rapidly. Our company breaks through the amorphousalloy transformer planar rolled iron core structure, combine the three-dimensional rolled iron corestructure and amorphous alloy strip with low-loss characteristics, developed a amorphous allovtransformer with high-strength iron core, short-circuit resistance, temperature rise, uniform, low noisethree-phase balance, low no-load current, material and energy saving, small leakage of magneticpeculiarities.
