Abstract (en)

[origin: EP2442321A1] The calotte (10) has hollow-cylindrical electrically conductive elements (12, 14) arranged around a rotational axis (20). Isolation barriers (30, 34, 38) are adapted to a form of the hollow-cylindrical element, and include flanged socket supports (30, 32) for feedthrough of a shielding pipe (26) to connection devices. The isolation barriers are spaced by isolation rings (42, 44, 46) that are arranged around the rotational axis, where the rings exhibit a wave form flattened in a radial direction.
