These insulators are Usually created from ceramic discs to ensure if they get wet, electricity leakage should take a much longer path to floor. These discs are relatively standardized, so This is often an uncomplicated way to get a tough guess of the transmission line’s voltage. Just multiply the quantity of discs by fifteen. By way of example, this line near my house has 9 discs on Every single insulator, and I comprehend it’s 138 kilovolt line. You’ll also normally see more compact conductors managing alongside the top of transmission lines. These static or shield wires aren’t carrying any latest. They’re there to shield the principle conductors against lightning strikes.
Flexible conductors supported at their ends approximate the shape of the catenary, and far on the Investigation for building of transmission lines relies on the properties of this form.[one]
