Cable transfer station
In electrical energy engineering, a cable transfer station , also known as a cable transfer station or cable garden , is a ground-level transition from an overhead line system operated with extra-high voltage to an extra- high voltage cable system designed as an underground cable . In the maximum voltage range from nominal voltages of 220 kV and up, the transition from the overhead line to the underground cable generally takes place via a separate cable transfer station.
The cable transfer station must always be fenced because it has high-voltage parts less than six meters above the ground. In the case of terminal masts for low and medium voltage lines , the transition from the underground cable to the overhead line is usually made on the mast without a separate cable transfer station, as is the case with 110 kV lines with plastic-insulated cables.
In addition to surge arresters and the specially designed cable ends , the system usually also includes additional isolators or circuit breakers and current transformers to record the current through the line, depending on the specific station .
