It might seem dangerous at first, but there’s actually a clever reason behind this design. In this video, we’ll look at how power lines carry electricity across huge distances, why aluminum is commonly used, how the surrounding air helps with electrical separation, and why engineers leave these wires exposed. From heat and weight to electrical safety and the surprising role of insulators, discover the engineering behind something we see almost every day. 00:03 Introduction 01:13 Why Electricity Needs Wires 02:24 Why Not Cover the Entire Wire? 04:01 The Real Reason Power Lines Are Bare 05:36 What Are the Wires Made Of? 06:50 Conclusion #PowerLines #Electricity #Engineering #HowThingsWork #ElectricalGrid #DidYouKnow #HistoryOfSimpleThings
