Episode notes
Take a closer look at the unsung heroes of modern infrastructure: the poles and lines that silently keep the electrical grid standing. This video explores the complex engineering behind transmission pole design, from how structures are calculated to withstand high winds, to the hidden strategies used to handle lightning strikes and electrical surges. It also examines how different materials—wood, steel, concrete, and composite—are chosen based on terrain, weather risk, and long-term durability, all while balancing cost and accessibility for maintenance.
The video also reveals the surprising ways these towering structures can fail under extreme conditions. From the crushing weight of ice storms that snap lines like thread, to the bending force of hurricane winds that topple even steel towers, we uncover real-world case studies of failures an ...
