Transmission Lines

Transmission Lines

Contacting any powerline with any object, including machinery, is extremely dangerous. Serious personal injury, property damage and fatality may result.

Even working close to powerlines, without actually touching them, can result in serious injury.

How close you can work or operate near powerlines depends on the powerline’s voltage as well as weather conditions including hot and/or windy weather – or storms where lightning strikes may cause voltage surges. The general rule is the higher the voltage, the greater the clearance required.

‘Clearance’ is the distance that must be maintained between a powerline and an object, to help avoid the risk of electric shock.

Always be aware of the location, voltage and clearance requirements of powerlines where you and your contactors are working, especially if you are working at an unfamiliar site – or when working at night.

There are many types of powerlines of differing voltage and design. ElectraNet operates and manages all high-voltage transmission lines, and the associated large tower structures that transmit electricity over vast distances and to remote areas in South Australia. ElectraNet’s transmission network operates at mainly 132,000 and 275,000 Volts.

Never guess at minimum clearances as appearances can be deceptive. Do not measure by touching, or by use of devices such as tape measures.
