1. A cable module for a high voltage gas-insulated device with a detachable electric connection, comprising:
an enclosure provided with a first opening and a second opening;
an insulator provided with a conductive insert and fixed to a first flange of the enclosure around the first opening;
a cable terminal connector passing through a wall of the enclosure and comprising a first end positioned inside the enclosure and a second end positioned outside the enclosure and configured to be connected to an external cable;
a plurality of conductors, comprising a first conductor electrically connected to the conductive insert, a second conductor electrically connected to the first end of the cable terminal connector, and a third conductor detachably and electrically connecting the first conductor to the second conductor; and
a fourth conductor fixedly connected to the first end of the cable terminal connector; wherein
the third conductor is configured to be movable relative to the enclosure substantially along a central axis of the second opening to be fixedly connected to or separated from the first conductor, and
the second conductor is configured to be movable relative to the fourth conductor along a direction perpendicular to the central axis of the second opening and is electrically connected to the fourth conductor through a second electrical contact embedded in the fourth conductor.
