防止电线或电缆在线槽内移动的措施

  (1)金属线槽布线搬适用于正常环境的室内干燥和不易受机械损伤的场所明敷,但对金属线槽有严重腐蚀的场所不应采用。

  (1) the metal wire slot wiring is suitable for indoor drying in normal environment, and is not easy to be damaged by mechanical application. But it is not suitable for places where serious corrosion occurs in metal wire groove.

  (2)同一回路的所有相线和中性线,应敷设在同一金属线槽内。同一路径无防干扰要求的线路,可敷设于同一金属线槽内,线槽内电线或电缆的总截面(包括外护层)不应超过线槽内截面的20%,载流导线不宜超过30根。控制、信号或与其相类似的线路,电线或电缆的总截向下应超过线槽内截面的50%,电线或电缆根数下限。

  (2) all the lines and neutral lines of the same loop should be laid in the same metal line slot. The same path without interference requirements can be laid in the same metal wire slot. The total section (including the outer sheath) of wire or cable should not exceed 20% of the inner section of the wire slot, and the current carrying conductor should not exceed 30. The total cut down of the wire or cable should exceed 50% of the cross section of the line slot and the lower limit of the number of wires or cables.

  (3)金属线槽垂直或倾斜安装时,济南电缆桥架应采取措施防止电线或电缆在线槽内移动。

  (3) when the metal groove is installed vertically or tilted, the Ji'nan cable bridge should take measures to prevent the wire or cable from moving in the online slot.

  (4)由金属线槽引出的线路,可采用金属管,硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤。

  (4) lines drawn from wire grooves can be wired with metal tubes, hard plastic tubes, semi hard plastic pipes, metal hoses or cables. The wire or cable shall not be damaged in the elicited part.

  (5)线糟应平整、无扭曲变形,内壁应光滑、无毛刺。

  (5) the line grains should be smooth and undistorted, and the inner wall should be smooth and without burr.

  (6)金属线槽应可靠接地或接零,但不应作为设备的接地导体。

  (6) metal wire grooves should be reliably grounded or zero, but should not be used as grounding conductors of the equipment.

  2、电缆桥架布线

  2. Cable bridge cabling

  (1)在室内采用电缆桥架布线时,其电缆不应有黄麻或其他易延燃材料外护层。

  (1) when cable bridge cabling is used indoors, the cable shall not have jute or other easy - to - burn material outer protective layer.

  (2)在有腐蚀或特别潮湿的场所采用电缆桥架布线时,应根据腐蚀介质的不同采取相应的防护措施,并宜选用塑料护套电缆。

  (2) when wiring cabling is used in corrosive or especially wet places, corresponding protective measures should be taken according to the different corrosive media, and plastic sheathed cables should be chosen.

  (3)电缆桥架(托盘)水平安装时的距地高度一般不宜低于2.50m,垂直安装时距地1.80m以下部分应加金属盖板保护,但敷设在电气专用房间(如配电室,电气竖井、技术层等)内时除外。

  (3) the height of the ground when the cable tray is installed horizontally is generally not lower than 2.50M. When the vertical installation is below 1.80m, the metal cover should be added to the protection, but it should be excluded when it is laid in the electrical special room (such as distribution room, electrical shaft, technology level, etc.).

  (4)电缆桥架水平安装时,宜按荷载曲线选取佳跨距进行支撑,跨距一般为1.5~3m。垂直敷设时,其固定点间距不宜大于2m。

  (4) when the cable bridge is installed horizontally, the best span should be selected according to the load curve, and the span is generally 1.5 ~ 3M. The spacing of the fixed point should not be greater than 2m when vertical laying.

  (5)几组电缆桥架在同一高度平行安装时,各相邻电缆桥架间应考虑维护、检修距离。

  (5) when several groups of cable bridges are installed at the same height, the distance between the adjacent cables should be considered for maintenance and maintenance.

  (6)在电缆桥架上可以无间距敷设电缆,电缆在桥架内横断

  (6) the cable can be laid on the cable bridge without a distance, and the cable is transected in the bridge.
