25KVA Lead Wire Three Phase Auto Transformer 380V/240V F/H Class

Feature:

(1) Since the calculation of the autotransformer is less than the rated capacity, under the same rated capacity, the main size of the autotransformer is smaller, and the effective materials (silicon steel, wires and structural materials (steel) are reduced accordingly. The effective materials are reduced to male the copper loss and iron loss are also reduced correspondingly, so the efficiency of the autotransformer is higher.At the same time, due to the reduction of the main size and the reduction of the quality, a single transformer with a larger capacity can be manufactured under allowable transportation conditions.

(2) Since the short-circuit impedance per unit value of the autotransformer is smaller than that of the double-winding transformer, the voltage change rate is smaller, but the short-circuit current is larger.
