Suriname cable tray bend expansion and contraction issues
Metal actually expands and contracts with weather change, and leaving some small gap in between tray sections is a must. When the distance between the metals is too low, the metals will push against each other and bend. It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion. The metal gets longer, and the heat becomes excessive. In case there is no space to move it, the tray could become deformed or break the bolts that attach. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
