Claims17
A coupling sleeve for connecting cable ends of high-voltage DC voltage cables by means of a connection body comprising at least five control inserts for controlling the electric field,
- wherein the connection body is made of an elastomer,
- wherein the control inserts are arranged to be layered and insulated from one another,
- wherein the control inserts are electrically conducting and neither semiconducting nor resistive, and
- wherein the control inserts are configured such that in transient processes, a capacitive field control can be generated, and wherein in transient processes, the capacities between the individual control inserts are effective, and the result is a field distribution according to a capacitive voltage divider.
