Insulator string on the overhead line
Insulator string is two insulator elements or more insulator elements assembly, suspension wire components. The effect of insulator string is suspension wire. Insulator string should also make wire and iron tower insulate with earth.
On the overhead line, if the iron tower is too high or voltage is too high, overhead line will need high voltage insulator string. Maybe it need long insulator string, maybe it need short insulator string. So insulator string for overhead line is very important.
Every insulator rated working voltage is certain on the overhead line, so insulator string connects the insulators to improve work voltage. Insulator string usually be used to suspension insulator.
Insulator string for high-voltage overhead transmission lines provide the mechanical insulator system between the live conductors and the pole.
