1. 拖链内电缆要直线排列，位置是拖链中间。
2.
安装垂直式拖链时参考下面技术材料：拖链最大运行距离不到四米，可不用支架；超过四米必须得用支架，防止低垂现象。3. 电缆、保护管分离方法：不同的电缆，保护管直径之和若超过拖链内腔高1.2倍时，不必用隔条。不到1.2倍时，必须安装隔条；所有的电缆或保护管直径不到拖链内腔高度的0.5倍时，必须得安装横隔条；电缆，保护管安装铺设时互相不要靠得太紧。当拖链必须铺设大量电缆，抑或直径相关太大时，拖链里必须安装纵横多层内隔板；电缆要直线排列，才不至于互相缠结，拖链里按电缆以前，电缆不应该受损伤，电缆线应于圆筒式线架上，笔直取下（不要弯折），保持其正常状态铺设入拖链内。
Usage ：
1.
The cables have to be arranged in a straight line in the cable chain, so it can be installed in the center of the cable chain inside.2. Please refer to below technical data if the cable chain can be installed vertical standing applications In case of the maximum strokes are less than 4m, it do not need the support. In case of the maximum strokes are more than 4m, it have to be used with support in order to prevent the cable chains from hand down.
3. Distribution of the cables or hoses: If the sum of cables and hoses with different diameter of bigger than 1.2 X chain inner heithe, no need divider between the two cables or hoses, however, if the sum is less than 1.2 X chain inner height, vertical divider must be used. _Horizontal separator must be used if the sum of cable or hose`s diameter is less than 0.5X chain inner height. Flat cables or in a circle cables and hoses should be loosened mutually in the chain. Chain have to be arranged separator and divider enough so that set in lots of cables or set in very different diameter`s cable. Cable must arrange straightly in the chain so that cable should not get tangled. Also cable should not damage and be in a straight line on the drum. After that this normal cable if able to put into the chain.
