How Electric Wires Are Made — From Copper to Power Lines | Inside Wire Factories

Ever wondered how electric wires are made? In this episode of The How Factory, we go inside large-scale electrical wire manufacturing plants to show how raw copper is transformed into the power lines that run homes, cities, and industries. Follow the full industrial process step by step — from copper rod casting and multi-stage wire drawing to annealing, insulation coating, cooling, spooling, and quality testing. You’ll see how high-speed machines stretch copper to precise diameters, apply protective insulation, and prepare cables for construction, utilities, and power grids. Electric wire production is a critical part of industrial manufacturing and energy infrastructure, requiring precision, conductivity control, and continuous automation. These factories operate nonstop to supply cables for buildings, machinery, renewable energy, and national power networks. This behind-the-scenes factory tour focuses on metal processing, electrical manufacturing, and real “how it’s made” style production used in modern wire factories.
