Why Are High-Voltage Power Lines Uninsulated While Household Wires Are Insulated?

When comparing low-voltage domestic wiring with extra-high-voltage (EHV) power transmission infrastructure, industry outsiders often encounter a paradox: Why are 220V/110V household cables wrapped in heavy insulation, while 500kV extra-high-voltage transmission lines hang entirely bare?

Why XLPE Cables Are the Preferred Choice for Modern Power Infrastructure

Compared with conventional PVC-insulated cables, XLPE cables offer significant performance advantages. Cross-linked polyethylene insulation provides higher operating temperatures, improved mechanical strength, and better resistance to electrical stress, allowing the cable to perform reliably under demanding conditions.
