SZ11 Series Three-phase Transformer (10kV/35kV)
Production introduction
The transformer with load voltage-regulating tap switches called on-load regulating transformer. Under the condition of not cutting load current, through tap switch, numbers of sub-joints will be led out from the transformer winding to change the sub-joint position and change its effective turn. That is, no change of the output voltage through changing the voltage ratio of the transformer. In the process of changing and sub-jointing cycling current is absorbed and limited by the transitional resistance.
Normal operation conditions
Level not exceeding 1000m indoor or out door
Highest environment temperature 40℃ highest average temperature daily 30℃
Highest average temperature yearly 20℃, lowest-25℃
According to user's requirement, we can supply the transformer that will operate under special condition
