Digging and excavation near power poles - Do not dig within 5.0 metres of one of our power poles without a Close Approach Consent. - Excavations within 5.0 metres could cause the pole to collapse! We will provide guidance and, in some instances this may be on-site. - Reminder: materials excavated become the new point of measurement to line.

Understanding the Basics: Primary vs. Secondary Pole Lines. Let's first establish the distinction between primary and secondary pole lines. Primary lines carry high-voltage electricity from substations to various distribution points, while secondary lines distribute this power to homes, businesses, and other end-users.

Take extra care to ensure that they don't inadvertently touch a power line. Call before working or lifting. The Occupational Safety and Health Administration (OSHA) requires anyone working or lifting within 10 feet of overhead power lines or poles to contact the appropriate utility. This distance could be greater when dealing with higher voltage.

High voltage transmission lines are overhead power lines used for efficient bulk power transmission. Since the power needs to be transmitted over long distances, the voltage level of transmitted power is increased to reduce the current to minimize I² R i.e., power losses during transmission. The lower the current, the lower the resistive losses in …
