A switchgear which includes a cable compartment enclosed by walls and a cover, and a cable connector arranged in the cable compartment. The cable connector is configured to electrically connect a cable to a cable bushing located in the cable compartment. cable connector includes a first portion to which the cable is connected and a metal plate arranged inside the cable compartment. The shortest distance between a main body and an outer surface of the first portion is in the range of 0 to 10 mm.

The present disclosure relates to a cable module with a detachable fracture feature, a gas-insulated device including the cable module, and a method for manufacturing the cable module. The cable module for a high voltage gas-insulated device with a detachable electric connection includes: 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 including 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 connecting the conductive insert and the first end of the of the cable terminal connector.

A medium voltage switchgear or control gear includes at least one first compartment; a cable compartment; a plurality of main components; and a plurality of auxiliary components. The plurality of main components is housed in at least one part of the at least one first compartment. The plurality of auxiliary components is housed in the cable compartment. The second connector is configured to connect to the first connector to connect a cable in the cable compartment to a component of the plurality of main components. The cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment.

Switchgear includes a duct by which inside portions of a plurality of cable compartments are linked each other; and a gas flow direction restriction device by which high-pressure gas is flowed only in a predetermined direction in the duct when the high-pressure gas is generated at the inside of any of the cable compartments in the plurality of cable compartments; in which the high-pressure gas can be ejected from a predetermined portion of the switchgear to the outside without increasing outer dimensions of the switchgear in accordance with an internal fault in the cable compartments.

A cable termination comprises, amongst other things, three insulated cable connection elements which project into a housing and have an internal conductor, and also three phase connection parts which are designed as hollow bodies and likewise project into the housing from a side which is situated opposite the cable connection elements and into each of which one of three cable end reinforcements can be inserted. The cable connection elements and the phase connection parts each form the corners of a triangle. These triangles are rotated in relation to one another in their respective plane, so that an offset is created. In order to bridge the offset, a connecting element is arranged between in each case one cable connection element and the associated phase connection part, the said connecting element being designed such that it can be partially or entirely removed in order to establish an isolating gap.

A cable testing device (6) integrated in high-voltage electrical equipment (3) provided with a main circuit (17), including at least one line connection (4) and one cable outlet (5); at least one control means comprising at least one switch (1a) and/or one disconnecting switch (1b, 1c, 1d). The testing device (6) stands out as it is installed as a first element upstream of the cable outlet (5) and at the same time downstream of the switch (1a) and/or of the disconnecting switch (1b)(1c)(1d), the testing device (6) being independent from the operation of the main circuit (17), such that the switch (1a) and/or the disconnecting switch (1b)(1c)(1d) keep their contacts in an open position during cable testing, the voltage to perform cable testing being injected into the cable outlet (5) through the testing device (6).
