As a matter of interest, what's the typical voltage of the three wires
connected to porcelain/glass insulators, mounted on wooden poles, that
feed the transformers (often pole-mounted) that step down to 240V for
overhead wiring to houses? I can't find anything on Google, using
phrases such as "overhead power line 240V" or "low voltage overhead
power line".
I thought they were 11 kV or 33 kV but someone who knows will be along
in a minute!
3.3kV and 6.6kV are also possible - but 33kV seems a quite common option
for a "whole district" type feed.
