Problems solved by technology

[0006] However, this method has the disadvantage that the implementation of the mentioned steps is relatively cumbersome and time-consuming
This is problematic especially in inaccessible places or in environmental conditions that do not allow prolonged stays, such as high temperatures, radioactive radiation, etc.
Especially if the insulation is made of powder and / or is hygroscopic, a long duration also leads to a reduction of the insulation resistance on open cables
In addition, other connection methods usually have the disadvantage that they cannot guarantee a sealed connection

Embodiment Construction

[0083] figure 2 Shown are two mineral insulated cables 100, 100' (MI cables), which respectively comprise electrically conductive inner conductors 110, 110', wherein the inner conductors are respectively surrounded by outer jackets 120, 120' made of stainless steel and inside Between the conductors 110, 110' and the jackets 120, 120' is compacted ceramic powder as insulating material 130, 130'. In the example shown, the two mineral insulated cables 100 , 100 ′ are constructed identically.

[0084] The two cables 100 , 100 ′ each have an end 101 , 101 ′ which can be formed by separating the cables, that is to say can be designed in particular as a split end or cut end. Thus, the ends 101, 101' of the two cables 100, 100' are characterized in that the inner conductor 110, the jacket 120 and the insulating material 130 of the cable 100 terminate at the same end point in the axial direction A; the same is true for the cable 100' .

[0085] The two MI cables 100, 100' should no...

Abstract

The invention relates to a method for connecting a mineral insulated cable to a further mineral insulated cable or connector, and to an arrangement comprising the mineral insulated cable, which is connected to a further mineral insulated cable or connector, the invention also relates to a cable or a connector, to a corresponding shaped element and to a kit for connecting two cables or connecting a cable to a connector.

Description

technical field [0001] The present invention relates to a method for connecting a mineral insulated cable to a further mineral insulated cable or a connector and to an arrangement comprising a mineral insulated cable connected to a further mineral insulated cable or a connector, It also relates to a cable or a connector, a corresponding shaped element and a kit for connecting two cables or for connecting a cable to a connector. Background technique [0002] Mineral insulated cables (MI cables) are used under extreme environmental conditions, for example in the case of high temperatures, high pressures, radioactive radiation and / or corrosive influences, and generally where aging of the cables should be avoided. As examples, installations in the deep sea, e.g. in oil and / or gas drilling or exploration installations, and / or in chemically or radioactively contaminated environments, e.g. in the chemical industry or in energy installations and reactor technology , especially in a...
