Cable terminations are used in routine, sample, and type testing of plastic-insulated medium and high voltage cables according to IEC 60840 (30-150kV) , IEC 62067 (150-550kV) , IEC 60060-1, IEC 60060-2 and IEC 60270. They act as the connection between the test object and the high voltage test system.
There are two models of cable terminations using different techniques depending on the test voltage of the cables to be tested.
Oil termination systems are used to test medium voltage cables with test voltages of up to 100 kV.
Water termination systems are used to test medium and high voltage cables with test voltages ranging from 75 kV to 800 kV. In addition to the water terminations they feature a water conditioning unit. When testing cables, the system extracts the produced heat losses via a closed water circuit and at the same time, monitors the conductivity of the resistive stress grader medium.
