A high-power plug connection system has a cable connection housing for connecting at least two electric high-power plug connectors in order to transmit and/or distribute a high current strength and/or a high electric voltage. The cable connection housing receives at least two insulating bodies for receiving at least one respective high-power contact and at least one electrically conductive rail in an interior. The rail is designed to establish an electrically conductive connection between the at least two high-power contacts, and the insulating bodies protrude at least partly out of the interior through a respective housing opening and into a connection region, the connection region being designed to receive the high-power plug connector.
