Overhead Power Lines

It is important to stay safe around overhead power lines, as well as around all other electrical distribution system equipment. In order to be safe, stay educated about the dangers related to overhead power lines. 

All power lines are dangerous and could deliver a serious or fatal shock to anyone who gets too close. The power lines mounted at the top of hydro poles are not insulated. This makes it much easier for someone in the vicinity of these wires to receive a shock resulting in injury or death. You do not need to be touching an electric wire to be electrocuted. Electricity can arc through the air to you, or a tool you are holding, and deliver a potentially fatal shock.

To ensure your safety, always remain at a safe distance from power lines. The minimum safe distance from overhead power lines varies depending on a line’s voltage:

Minimum safe distance from power lines
Power line voltageDistance in metres
Lower than 750 volts1.0 (3 ft.)
750 – 150, 0003.0 (10 ft.)
150, 001 – 250, 0004.5 (15 ft.)
250,001 and higher6.0 (20 ft.)


These minimum safe distances apply not only to people, but also to tools, trees and toys. If you are working with tools, such as ladders or tree clippers, keep them a safe distance from overhead power lines. 类似的, ensure that children do not play with aerial toys, 如风筝, near overhead power lines.

To ensure your safety, familiarize yourself with the location and voltage of the power lines around your home.

Almost any type of material has the potential to conduct electricity in varying degrees. Always assume that an object in contact with or very near an overhead power line is electrically charged. When dealing with objects in contact with power lines, contact bat365官网登录 寻求帮助, and always remain at a safe distance from overhead power lines and the objects in contact with them.

Trees Contacting Overhead Power Lines

Trees that are very near or come into contact with overhead power lines can interfere with safety and reliability of electricity delivery and pose safety hazards to the public. In order to mitigate contact between trees and overhead power lines, bat365官网登录 runs a year-round 树修剪 程序.

You must use caution when pruning trees that are close to power lines. Do not attempt to prune a tree if it, 或者任何一部分, comes within the bat365官网登录 clearance area (within 3 metres of a power line). Instead, you should submit a non-electrical service request 在线. 类似的, ensure that as you prune trees, no part of yourself, 你的梯子, or your tools come within the bat365官网登录 clearance area.

If you have general questions and you are unsure of whether a tree is safe to prune, visit our 树修剪 webpage for more information or beat365登录 寻求帮助.
