- a cohesive composite can be done for example by welding or soldering the projecting shoulder in the encapsulating. Since encapsulating housing are formed in particular in medium and high voltage range as well as a gastight Kapse ⁇ lung housing, they must have sufficient mechanical stability at a Vorse ⁇ hen an overpressure in the interior of the encapsulating housing. This is usually achieved by the use of metallic materials for the encapsulating.

Furthermore, the possibility exists, on the projecting shoulder only the To attach transducer or only the insulator assembly. This enables a more variable use of the connection module.
- a further advantageous embodiment can provide that the insulator arrangement has a disk insulator.
- a disk insulator is an insulator which has a planar extension which is pierced by an electrical conductor to be held, wherein the electrical conductor is surrounded by insulating material substantially transversely to its longitudinal axis.

- the disk insulator is sealed or supported on the projecting shoulder so that the insulating material, which is brittle in comparison to the housing material, is stabilized.
- the disc insulator is additionally surrounded by a socket fitting, with which it is connected and the socket fitting is in contact with the projecting shoulder.
- the disk insulator can be a single-phase disk insulator or a multi-phase disk insulator.
- a multiphase disk insulator a plurality of electrical conductors are kept electrically isolated from one another by means of one or more disk insulators.

So it is for example possible to open by means of the circuit breaker, an electrically lei ⁇ tend connection between a terminal block in the single-run line and the electrical switch.
- an earthing switch By means of an earthing switch, it is possible to commission for Studentstra ⁇ supply provided electrical power conductor portions in the interior of the encapsulating housing to ground potential beat. This is necessary for security reasons, for example.
- Switching devices come during a switching operation to the occurrence of discharge phenomena. It is advantageous if, by means of the insulator arrangement, a division of the volume available in the interior of the encapsulating housing is undertaken, so that at least partially arranged electrical switching devices are separated from the measuring transducer within the encapsulating housing. As a result, the transducer is protected against arcing phenomena. Furthermore, the use of sulfur hexafluoride under elevated pressure has a decomposing effect, which occurs as soon as arcs are formed. The resulting decomposition products could damage the transducer. Therefore, a separation of the transducer from other assemblies in the interior of the encapsulating housing by means of the insulator arrangement is advantageous.
