Cable module, gas-insulated device, and method for manufacturing cable module

A method for manufacturing a cable module for a high voltage gas-insulated device with a detachable electric connection, comprising:

• providing an enclosure having a first opening and a second opening;
• providing an insulator having a conductive insert;
• providing a first conductor electrically connected to the conductive insert, and fixing the assembly of the insulator with the first conductor to a first flange of the enclosure around the first opening;
• providing a cable terminal connector having a first end and a second end;
• providing a second conductor electrically connected to the first end of the cable terminal connector, and passing the assembly of the cable terminal connector with the second conductor through a wall of the enclosure such that the first end is positioned inside the enclosure and the second end is positioned outside the enclosure to be connected to an external cable;
• providing a third conductor detachably and electrically connecting the first conductor to the second conductor, 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
• providing a fourth conductor fixedly connected to the first end of the cable terminal connector, and wherein 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.
