Transmission overhead powerlines

Transmission overhead powerlines range in voltage from 132kV up to 500kV. They are installed on towers or steel poles.


Transmission lines are typically installed in easements and permission is required before any work can be undertaken on the easement.

No Go Zones for towers

  1. Work outside 10m from overhead power lines no specific requirements are established other than those described in established regulation, primarily the Victorian Occupational Health and Safety Regulations 2007.
  2. Work between 10m and 8m from an overhead power line, a registered spotter is required. This is known as the Spotter Zone.
  3. Work within 8m from an overhead power line, permission from the relevant network operator is required.

ESV produces stickers (pictured below) outlining the exclusions listed above. These are available via our Merchandise page.
