This extract was what I was thinking of from AS61000.3.7. Not sure if there are other references though.
"...NOTES
1 This Standard uses the following terms for system voltage:
– low voltage (LV) refers to UN ? 1 kV;
– medium voltage (MV) refers to 1 kV < UN ? 35 kV;
– high voltage (HV) refers...
Can someone point me to where the definition of HV and MV is made in one of the AS Standards. It seems that there is more and more reference made to HV being above 1kV and less reference to MV/HV.
From memory (and this is a bad thing in my case), MV was 1000V up to but excluding 66kV, and HV...
Although I have had no response to my question, further research has led to me to continue with my recommendation to use aluminium conductors as I am unable to find any significant recorded issues against aluminium conductors.
I have had to conclude that the concerns were fueled by poor...
Sorry, I should have included that I did read the following thread, but it didn't cover what I was specifically looking for.

I am currently putting together a justification to install aluminium conductor 6.6kV cables on a relatively large project we are working on. The major advantage being the significant cost savings that can be made using the aluminium conductor cables rather than copper.
A query has been raised...
