A fluid-tight line feedthrough for introducing an electric conductor into a high-pressure chamber includes a housing and an electric conductor that passes through the housing. A ceramic insulator is positioned between the housing and the electric conductor. The ceramic insulator is divided into a first insulator segment facing the electric conductor and a second insulator segment facing the housing, thereby forming a conical separating plane. A fitting made of an electrically conductive material is positioned between the two segments, the fitting being connected to the two segments and to the housing.
