Indoor Vacuum Load Switch

PRODUCT STRUCTURE

FN12-12D and FN12-12DR combination appliances are three-phase high-voltage switchgear with rated voltage of 12KV and ratedfrequency of 50Hz for splitting load current, closed-loop current, no-load transformer and cable charging current, closingshort-circuit current, fuse combination The short-circuit current can be interrupted, and the load switch equipped with thegrounding switch can withstａnd the short-circuit current. It is mainly used in the urban substation and industrial power equipment with three-phase ring network or terminal power supply. It is used for load control and short circuit protection.

OUR SERVICE:

1, For transformer whose rated capacity is 500 KVA and below, the load loss value above the slash in the table is suitable for Dyn11 or Yzn11 connection groups, and that below the slash for YynO connection groups.

2, Transformers whose HV tapping range is ±2×2.5 may be provided, if need be.

3, Transformers whose LV is 0.69KV may be provided, if need be.

4, Users may choose other loss values as they need.

5, Due to product upgrading and changes to the external dimensions and products in the table, please refer to the external dimensions provided at the time of ordering.
