电缆桥架与管道安装的距离要求

一、电缆桥架与各种管道平行架设时,其净距离应满足下列要求:
1、 When the cable tray is erected in parallel with various pipelines, the net distance shall meet the following requirements:
1、电缆桥架与一般工艺管道(如压缩空气管)平行安装不少于400毫米。
1. The cable tray shall be installed parallel to the general process pipe (such as compressed air pipe) at least 400mm.
2、电缆盘和腐蚀性液体管道平行安装不少于500毫米。
2. The cable tray and corrosive liquid pipe shall be installed parallel at least 500mm.
3、电缆盘应该不是运输腐蚀性液体在高于或者低于腐蚀性气体管道平行安装。当无法避免,不应少于500毫米。和应用在防腐板。
3. Cable trays shall not transport corrosive liquids in parallel with pipes above or below corrosive gas. When unavoidable, it should not be less than 500 mm. And applied in anticorrosive plate.
4、电缆桥架与热管平行安装,热管与绝缘层不小于500毫米,没有隔热层不小于1000毫米。
4. The cable tray shall be installed in parallel with the heat pipe, and the heat pipe and insulation layer shall not be less than 500mm, and the insulation layer shall not be less than 1000mm.
5、电缆盘不应该平行上部的热管装置,当不可避免的需要高于热管平行安装,不得小于1000毫米,有效隔热应采取的措施。重庆桥架就到鹏泽电器。
5. The cable reel shall not be parallel to the upper heat pipe device. When it is unavoidable to install the cable tray higher than the heat pipe in parallel, it shall not be less than 1000mm, and the effective insulation measures shall be taken. Chongqing bridge to Pengze electric appliance.
 
二、电缆桥架与各种管道交叉时,其净距离应满足下列要求:
2、 When crossing the cable tray, the following requirements shall be met:
1、与一般的电缆桥架十字工艺管道,不少于300毫米。
1. Cross process pipe with general cable tray, no less than 300 mm.
2、电缆盘和腐蚀性液体管道低于十字之上或腐蚀性气体管道,不得小于500毫米,十字路口与不锈钢板将电缆保护托盘和盖板长度应不小于2000毫米d ,因为管直径(d)。
2. The cable tray and corrosive liquid pipe lower than the cross or corrosive gas pipeline shall not be less than 500mm. The length of cable tray and cover plate shall not be less than 2000mm D for the pipe diameter (d).
3、有线跨线桥与热管,热管与绝缘层,不得小于500毫米,没有隔热层,不应小于1000毫米,和应用程序在角落的隔热板(如石棉板)将电缆保护托盘和隔热板长度应不小于d 2000毫米。(d为热管绝缘外径)
3. Cable overpass with heat pipe, heat pipe and insulation layer shall not be less than 500mm, without insulation layer, it shall not be less than 1000mm, and the application of insulation board in corner (such as asbestos board) will protect cable tray and insulation board length shall not be less than D 2000mm. (D is the outer diameter of heat pipe insulation)
