The objective of this Handbook is to provide guidance for both transmission and distribution lines in relation to the application of AS/NZS 7000:2016. Typical distribution voltages are 230/400 V, 230/460 V [referred to as low voltage (LV)] and 6.6 kV, 11 kV, 12.7 kV, 19.1 kV, 22 kV [referred to as high voltage (HV)]. Typical sub-transmission voltages are 33 kV, 66 kV, 110 kV, 132 kV and transmission voltages are 220 kV, 275 kV, 330 kV, 400 kV and 500 kV.
