Maybe the angle of the photo is deceiving, but there doesn't appear to be much clearance for half a million volts!
John,
Thanks for the info. It just looks odd to see overhead lines and insulators on metal poles. I don't ever recall seeing that combination before, even in America.
Over here metal lamp standards are always wired underground. Where lights are needed with overhead wiring, they're generally just individual bracket lamps fitted to each wooden pole (although overhead lines in areas built-up enough to have street lights have disappeared rapidly in the last 20 years or so).
They ran PVC to the new poles from the OH grid, and ran triplex to each pole. The ground (earth) consisted of a driven ground rod at each pole.
Do you mean that the metal poles were connected
only to a ground rod, and not bonded to the neutral in any way whatsoever? (What would be called a "TT" system here.) If so, then is the feed via a GFCI ?
