ABSTRACT:
A compressed gas insulated high voltage line which has a metal encapsulation and supports the high voltage conductors on support insulators in which movability of the conductor in the axial direction relative to the encapsulation is provided by means of at least two parallel, sliding guidance pins extending parallel to the axis of the high voltage conductor and the encapsulation. The pins are connected to one end of the support insulator and provide longitudinal movability for accommodating length changes of the high voltage conductor relative to the encapsulation under thermal stress.
