In some dielectric tests of cables with large cross-
sections up to several thousand square
millimeters, the conductor must be preheated to a
specific temperature by current flow. For this
purpose, a current of several thousand amperes
must be fed into the conductor for the duration of
the test. In order to achieve this, a detachable
current-carrying connection is required, which
ensures a stable electrical contact and long-term
behavior during the test. A contact system was
therefore developed to establish the electrical
contact to the Milliken conductor on the face side.
This is necessary in order to feed the current
evenly to the individual strands of the conductor,
as these are insulated against each other. The
paper presents the patented contact system and
the connection geometry as well as the results of
a functional temperature-rise test in the laboratory.
