These insulators are Ordinarily made out of ceramic discs to make sure that if they get wet, electric power leakage needs to take a for much longer route to floor. These discs are relatively standardized, so This can be a simple way to get a tough guess of a transmission line’s voltage. Just multiply the amount of discs by 15. As an example, this line near my household has 9 discs on Every insulator, and I understand it’s 138 kilovolt line. You’ll also frequently see smaller sized conductors working alongside the highest of transmission lines. These static or shield wires aren’t carrying any present-day.
