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.

在安裝電纜橋架系統(tǒng)時，應考慮熱收縮和熱膨脹。直線電纜橋架的長度運行，溫差控制所需的伸縮拼接板的數量（見表1）。電纜托架應錨定在靠近其中間點的支撐板之間，并在所有其他支撐位置上用膨脹導向器固定（見圖1）。電纜托盤應允許縱向運動從這兩個方向的固定點。
