**You're looking at the BEATING HEART of the power grid being built. This process is absolutely mesmerizing.**
Get a front-row, first-person seat hundreds of feet in the air to witness a crucial step in building our infrastructure. This video shows a massive pulley block (or sheave) being used to smoothly guide a running board, which in turn strings brand new, heavy-duty electrical conductors across a huge valley. It's a hypnotic display of power, precision, and incredible modern engineering.
This is the unseen work that keeps your lights on.
