    1、YTTW电缆安装方式同普通电缆一样不需要专业人员,也不需要进行安装培训,遵照厂家所提供的安装施工要领及注意事项,安装前厂家均可派人做指导。

     2、电缆盘直接到现场进行放线,放线时可以从上至下,也可以从下至上。

     3、电缆的支架与固定 a水平吊架允许跨距1)电缆外径≤20mm,允许跨距400mm;2)电缆外径>20mm,允许跨距800mm b垂直支架允许跨距1)电缆外径≤20mm,允许跨距1500mm;2)电缆外径>20mm,允许跨距1000mm c在电缆桥架中敷设,固定电缆允许跨距可参照a、b项 d电缆敷设时允许存在自然的蛇形,但弯曲凸度应≤2D,D为电缆外径 e单芯电缆绑箍固定严禁采用磁性材质,例如铁丝等 f单芯电缆不能单根穿越此次那个材质管及闭合的任何形状的磁性构件,必须穿过钢管时又不能三相四线一起穿,应将每根钢管锯开一条缝才能穿过。
