Expansion Track sections are for use where it is necessary to compensate for the difference in total expansion or contraction between steel track housings and copper bus bars. They must be used on installations across building or structural expansion joint.

At least one Expansion Track section should be installed in each 400 ft. of track run. Additional Expansion Track sections may be required if the installation is subjected to a wide range of temperature changes.

The standard 10' Building Expnasion track section is designed to provide 2" of expansion and 2" of contraction of the steel housing above and below the normal 10' length at 72°F). If the temperature at the time of installation is other than 75°, due comensation must be made according to the chart below. The bus bars and track housing in this section telescope to provide a continuous surface for trolley contacts and the ball bearing support wheels of the trolley. Enclosed flexible jumpers connect the bus bars and maintain full current carrying capacity across the joints.
