By means of using the expansion joint structure, a mechanical gap formed at the place of connection of the busbars at two ends due to thermal expansion and contraction can be effectively compensated for, thus implementing smooth transitioning and continuous current-taking when a. Busbars, pins and terminals are critical electrical interfaces in electrified systems – especially where oil, coolant, gas, pressure or aggressive environments meet sensitive electronics. These elements not only transfer electrical current from one rigid conductor to the. A busbar expansion joint, which is mounted between two busbars in a rigid catenary system that are arranged in parallel according to a fixed spacing along the longitudinal direction of a line, and are provided with deflectors (1, 2) and an electric connection device (4); the inner side of each. Expansion Joints will be installed where extensions, vibrations or switching impacts have to be absorbed. It may be a consequence of an inappropriate mounting or unequal width of the busbars or.
