  The outer part of cable chamber is buried underground and protected by welded steel pipe when passing. Protective pipes placed in dusty and humid areas should be sealed. Cables should be laid along the nearest line to minimize bending. If the protective wire exceeds a certain length, the junction box should be installed, and the location of the junction box should be convenient for threading. The opening of the box body should be neat and in line with the diameter of the pipe.
  2. 绝缘电阻的振动测量
  2. Vibration Measurement of Insulation Resistance
  所有电器安装完毕后,应通过振动测量绝缘电阻。在振荡过程中,应断开线路上所有开关、刀门、仪器、设备和电气开关。确认振动正确后,即可进行输电试验。
  After all electrical appliances are installed, the insulation resistance should be measured by vibration. In the course of oscillation, all switches, knife doors, instruments, equipment and electrical switches on the circuit should be disconnected. When the vibration is confirmed to be correct, the transmission test can be carried out.
  3.安装照明装置
  3. Installation of lighting devices
  荧光灯的安装:在同一房间内,单盏灯在中心,多盏灯成直线安装,其偏差在50毫米以内;荧光灯与吊索链、吊索链与灯管相互垂直,吊索链相互平行。其他灯具的安装:根据灯具的外形尺寸达到安装位置,可靠地固定灯具,将线头包好紧贴天花板,不能外露。

The inside and outside of the paint box I are clean, the cover and switch are flexible, the circuit number is clear, the connection is neat, and the installation of PE wires is obviously firm. When installing the distribution cabinet, first adjust the straight line position, and fix the installation according to the labeled position.
  5. 安装防雷接地系统
  5. Installation of lightning protection grounding system
  采用Tn-s一体化接地,并设置专用PE地线。施工材料要求:防雷接地系统所有金属部件均应镀锌,锌层均匀,无锈蚀及锌层剥落现象。工程使用的材料必须具有资质证书,经现场监理和技术人员验收合格后方可使用。
  TN-s integrated grounding is adopted, and special PE grounding wire is set up. Construction Material Requirements: All metal parts of lightning protection grounding system should be galvanized, the zinc layer should be uniform, no corrosion and zinc layer spalling phenomenon. The materials used in the project must have the qualification certificate, which can be used only after the site supervision and technical personnel have passed the acceptance.
