1. This switch is the tapping regulating and changing equipment of the capacity regulation transformer under the condition of non excitation. They are applicable to the three phase oil immersed capacity regulation transformer with voltage grade of 10KV or less, capacity of 315KVA or less. It can carry out the switching of the series parallel connection of the high voltage and the series parallel connection of the low voltage under the condition of non excitation in order to transfer the capacity of the transformer to perform the function of gerulating capacitance and regulating voltage.

2. High-voltage/Low-voltage 10/0.4 KV

3. High-current/Low-current 20/500 A

4. Suitable for Max. Transformer ≤ 315 KVA
