摘要
Once the base piece and the support element are in contact with the electrical branch (20,21), and damage of the sliding bearing allows the passage of the current between the base piece and the support element. The tension device has a tension unit (1) having a fixed base piece (2) connecting by a rotating bearing (14) to a support element (5) mounted pivotingly on the base piece, this support element having a roller (9) guided against a traction unit (10). There is a torsion spring (11) interposed between the base and the support element, ensuring a support by the force of the roller against the traction element. There is an annular piece (7) delimited radially by the base piece and the support element receives the sliding bearing (6), this sliding bearing ensuring the metallic or electrical separation between the base piece and the support element.
