Transformer Project for RAAF Air Force Base Darwin

three phase transformer

This project was for the RAAF air force base at Tindal near Darwin in NT.

It was a complex job with 11 3 phase transformers ranging in Kva from 350kva to 2500kva.

The  voltage ratings were 11kv/415v 3 ph , with +/-2.5and 5% taps on the HV side.

All the transformers were epoxy cast/ air cooled and indoor rated. The insulation class was class F (155 Deg C). The manufacturing standard was AS/NZS 60076.11 “ Dry Type Power Transformers”

All units had separate input and output cable boxes.

The complexity was the cable box design, that had to accommodate some very large 3 phase cables .
