1. A method for greasing a contact wire for the electrical power supply of a pantograph of a rail vehicle comprising:
inserting the contact wire (14) into a passage opening (25) of a base body (21) that comprises a guide body part (22) and a cover part 23 extending in a longitudinal direction (1), a transverse direction (11) perpendicular to the longitudinal direction (1) and a height direction (9) perpendicular to the longitudinal direction (1) and perpendicular to the transverse direction (11), whereby the passage opening (25) penetrating the base body (21) in the longitudinal direction (1) as seen from a front side to a back side as seen in the longitudinal direction (1) and wherein the cover part (23) is placed on an upper side of the guide body part (22), seen in the height direction (9); a groove (24) extending in the longitudinal direction (1) is formed on an upper side of the guide body part (22) seen in the height direction (9) and is open in the longitudinal direction (1) at the face sides of the guide body part (22), so that a groove (24) is closed between the cover parts (23) and the guide body part (22), and forms the passage opening (25) through the base body (21), so that the contact wire (14) can be inserted into the groove (24), and
accelerating the base body (21) in the longitudinal direction (1) so that the contact wire (14) is moved through the passage direction, characterized by
introducing grease (54) into the passage opening (25) through which the contact wire (14) moves at a feed rate (59) at which the introduced grease (54) exits the passage opening (25) at the back of the base body (21) under a predetermined condition.
