It is important that thermal contraction and expansion be considered when installing cable tray systems.  The length   of the straight cable tray runs and the temperature differential govern the number of expansion splice plates required (see Table 1). The cable tray should be anchored at the support nearest to its midpoint between the expansion splice plates and secured by expansion guides at all other support locations (See Figure 1). The cable tray should be permit- ted longitudinal movement in both directions from that fixed point.

在安装电缆桥架系统时，应考虑热收缩和热膨胀。直线电缆桥架的长度运行，温差控制所需的伸缩拼接板的数量（见表1）。电缆托架应锚定在靠近其中间点的支撑板之间，并在所有其他支撑位置上用膨胀导向器固定（见图1）。电缆托盘应允许纵向运动从这两个方向的固定点。
