1)电力设备电缆不应和输送甲、乙、丙类液体管道、可燃气体管道、势力管道敷设在同一管沟内。
1) The power equipment cable shall not be laid in the same trench with the pipeline conveying class A, B and C liquid, combustible gas and power.
2)配电线路不得穿越通风管道内腔或敷设在通风管道外壁上,穿金属管保护的配电线路可紧贴通过管道外壁敷设。
2) The distribution line shall not pass through the inner cavity of the ventilation pipe or be laid on the outer wall of the ventilation pipe. The distribution line protected by metal pipe can be laid close to the outer wall of the pipe.
3)配电线路敷设在有可炮灰物的闷顶内时,应采取穿金属管等防火保护措施;敷设在有可燃物的吊顶内时,宜采取穿金属管、采用封闭式金属线槽或难燃材料的塑料管等防火保护措施。
3) When the distribution line is laid in the closed roof with gunpowder, it should take fire protection measures such as metal pipe; when it is laid in the ceiling with combustible materials, it should take fire protection measures such as metal pipe, closed metal trunking or plastic pipe of flame-retardant materials.
