BUSBAR FOR HOLDING A CONTACT WIRE, RIGID OVERHEAD CATENARY SYSTEM AND RAILTRACK COMPRISING SUCH A BUSBAR

This busbar (120) for holding a contact wire (110) has a section comprising a base (122), from which two holding arms (124) are extending downward, each comprising a clamping portion (128) configured to clamp onto the contact wire (110). The two holding arms (124) delimit an inner volume (V120) of the busbar (120). Each clamping portion (128) also comprises a protective wall (132), which extends within the inner volume (V120) and which is configured to prevent water condensing on the busbar (120) within the inner volume (V120) to flow by gravity to the clamping tips. For better protection of the contact wire, the two protective walls (132) include an upper wall (134) and a lower wall (136), which overlap each other and delimit a volume (V132) configured to be filled with a paste, such as grease.
