20kv 630kVA Prefabricated Compact Substation Transformer
Rooq's three-phase pad-mounted transformer is offered in a variety of designs and configurations.Some special designs and options may require additional engineering, factory coordination, unusual application requirements or special manufacturing needs.Higher impedances limit secondary fault currents such that coordination with secondary low voltage moldedcase circuit breakers is usually possible. (Low impedances are also available if required for paralleling, and so on.) Standard color is pad-mounted green.
Products Parameters
1 - Common power ratings: 30 - 2500 kVA.
2 - Designed for voltages of ≤ 36 kV. Specific figures are not given for this parameter because of the wide variety of voltages used.
3 - Transformers can be supplied on demand to run at two different primary voltages, the shift between these input voltages has two
basic alternatives:
4 - with a primary tap changer which can be switched with no load and no applied voltage or by changing terminals under the cover.
5 - The secondary voltage under no load is allocated at 400V, 415V, 433V, though other voltages can be supplied on demand.
6 - When usage requires two voltages, transformers with two simultaneous voltages can be supplied. In this case the no-load voltages are set to 400V(230V),415V(240V),433V(230V) .
7 - Accordance with the highest voltage for the material,being the level immediately above the rated voltage.
| Material maximum admissible voltage | 12kV | 17,5kV | 24kV | 36kV |
| Withstand voltage | 28kV | 38kV | 50kV | 70kV |
| Basic insulation level | 75kV | 95kV | 125kV | 170kV |
