Abstract
An insulation piece for a pipeline conveys electrically conductive liquids from a point that is at a ground potential to a point connected to a high voltage. The liquid is conveyed discontinuously by portion-by-portion transport by the carriage flow of the liquid being interrupted. The insulation piece is periodically free of liquid, corresponding to the interruptions in the carriage flow. The insulation piece is a hollow body, and its unobstructed width is equal to or greater than that of the pipeline. Connecting pieces for connecting to the pipeline are provided on the end faces of the insulation piece, which are closed in places by terminating elements, and which connecting pieces are of the same diameter as the adjacent pipeline. The connecting pieces pass through the terminating elements, rest against them to form a seal, and each have a toroidal-form attachment on the outside at their inner end.
