1. A transmission cable joint for a medium voltage underground cable system, comprising at least
a casing and
connection terminals,
wherein the casing encompasses components of the cable joint,
wherein the connection terminals belong to the components of the cable joint,
wherein the connection terminals is configured to couple wires of medium voltage transmission cables so that the cables are coupled to each other,
characterized in that
the cable joint further comprises a casing-encompassed inductance component that is connected with the connection terminals for limiting capacitive earth fault current, when the coupled cables produce such current.
