Case 3: Steel Conductor Rail on Steel Load Profile
No expansion module needed, since there is no differential expansion. Except for building expansion joints:
see chapter 5.1
7.2.4
Case 4: Steel Conductor Rail on Aluminum Load Profile
The aluminum load profile expands more during changes in temperature than does the steel conductor rail.

NOTE!
After adjusting the gap, be sure that it cannot slip more during later installa-
tion.
7.3
Installing an Air Gap
Air gaps without expansion distance and without electrical bypass
Air gaps can be used anywhere. When used in a curve, two additional hanger clamps are required. Gaps can also be
retrofitted.
To do this, cut a 46 mm piece out of the rail at the desired point
Deburr the rail ends cleanly (see BAL0815-0002-EN)
