| 摘要 |
The invention relates to a power transmission system (1) for the power transmission of an electrical power (P) from a power source (2a) to a power sink (4A) that is connected to the power source (2A) via a power transfer cable (3), wherein the power source (2A) has a first pole with a first electrical potential, connected to a first pole of the power sink (4A) via parallel power supply lines of a first line pair of the power transfer cable (3), and a second pole with a second electrical potential, connected to a second pole of the power sink (4A) via additional parallel power supply lines of a second line pair of the power transfer cable (3), wherein, during the power transmission via the power supply lines, a user data signal can be transmitted between the power source (2A) and the power sink (4A) via at least one line pair with power supply lines of the same electrical potential, unaffected by the power transmission. |
