Flameproof Transformer Station type IT3Su
The flameproof transformer station type IT3Su is designed to supply equipment with a rated voltage of 380 VAC to 1140 VAC and is suitable to supply frequency converters.
DESIGN:
The enclosure of the transformer station IT3Su consists of five flameproof compartments:
- connection compartment with cables or rubber cables supplying the transformer station;
- high voltage (HV) compartment housing switchgear;
- transformer compartment;
- low voltage (LV) compartment housing switchgear and protection equipment;
- connection compartment housing outgoing feeder rubber cables and control cables.
Transswitch type version:
- station can be delivered with more outgoing feeders on the low-voltage side,
- up to nine main outgoing feeders on the low-voltage side,
- possibility for installing auxiliary and control outgoing feeders,
- possibility for putting in main outgoing feeders in the form of retractable replaceable inserts,
- independent safety features for each main outgoing feeder.
