Abstract
An exemplary isolating tube, and production method thereof, includes a mechanically load-bearing plastic tube composed of a fiber-reinforced polymer for use in a cooling element which can be loaded with high voltage, during whose operation the isolating tube forms an electrical isolation gap and in the tube interior carries an agent which flows as a liquid and/or vapor. The isolating tube can have a diffusion barrier which is held coaxially by the plastic tube. Such an isolating tube can be produced using an exemplary novel method for production.
