Title:

LEAD-OUT TUBE

Document Type and Number:

WIPO Patent Application WO/2011/020575

Kind Code:

A1

Abstract:

The invention relates to a lead-out tube (10, 30, 60) for high-voltage transformers, comprising a shield tube (12, 32, 62) made of an electrically conductive material. The shield tube extends in a hollow cylindrical manner around a path (14, 34) and in the axial direction thereof, said path being curved at least in sections. The lead-out tube also comprises a molded hollow cylindrical electric insulating layer (16, 48, 49, 70, 78) which lies at a first radial distance (20) around the shield tube (12, 32, 62) and along the axial extension thereof. The insulating layer (16, 48, 49, 70, 78) is wound from a band-shaped insulating material around strips (18, 36, 38, 40, 42, 44, 66, 68, 80, 100, 120) which are flexible at least in sections (82, 102, 122), said strips lying adjacent to each other at a second radial distance (22) around the shield tube (12, 32, 62) and along the path (14, 34) which is curved at least in sections.
