ABSTRACT:
An electrical lead-through bushing with an internal conductor surrounded by an external conductor, extending together through a flange element, is particularly suitable for a TDR (time domain reflectometry) measuring system in which the fill level in a reactor pressure vessel of a nuclear installation is monitored. The bushing is particularly suitable for use on a vessel wherein comparatively high pressures and/or high temperatures may prevail. For this purpose, a first space region, formed on a first side of the flange element between the internal conductor and the external conductor surrounding it, is sealed off with respect to a second space region, formed on a second side of the flange element by the internal conductor and the external conductor surrounding it, by way of a number of sealing rings.
