Cable compensation device applied to tramcar overhead line system

The invention relates to a cable compensation device applied to a tramcar overhead line system, which comprises a bracket body for supporting a cable and hanging the overhead line system; the bracketbody is a wing-shaped structure and comprises at least one bracket base, at least one cable tray, at least four cable clamps and at least two stiffening ribs. The cable compensation bracket installingstructure consisting of one bracket base, one cable tray, four sets of cable clamps and two blocks of stiffening ribs can realize the safe folding and unfolding of the compensation cable; except forthe compensation cable, the cable compensation bracket is also featured by good appearance, adaptation to the box body structure, and safety and stability. The cable compensation and segmental insulator installing bracket structure consisting of one bracket base, two cable trays, four sets of cable clamps and four stiffening ribs can realize the safe folding and unfolding the compensation cable and stably installation of th
