DRIVING ROD FOR MEDIUM VOLTAGE SWITCHING ELEMENT GEAR

摘要

The invention relates to a device for medium or high voltage switching element gear, the device comprising: - a switching element for connecting two conductors; and - a driving rod for operating the switch; wherein the driving rod comprises at least a surface layer of an electrically high resistance material. The electrically high resistance material ensures that a small current will flow through the material due to the present electrical field. This small current will cause a heating of the driving rod, such that condensation is reduced or prevented.
