What are the precautions for the electrical construction of the packing box room?

The industrial development speed of packing box houses can be described as unstoppable. In recent years, packing boxes have been widely used in temporary offices, dormitories, transportation, water conservancy and other construction sites on construction sites. The box-type integrated house is gradually forming a trend, which is a veritable environmental protection green building, which is conducive to protecting the environment and saving energy. But one thing they need to pay attention to is the electrical construction part, which is easily overlooked by people. So what are the precautions for electrical construction of packing box manufacturers? (1) Cable laying and protection measures for packing boxes The outdoor part of the cable is directly buried in the ground, and it is protected by welded steel pipes when passing by. The protective pipeline laid in dusty and humid places, the nozzle and the connection of the pipe should be sealed. Cables in boxes should be routed along the nearest line with as few bends as possible. When the protective pipeline exceeds a certain length, a junction box should be added. Its position should be convenient for threading. 2. Insulation resistance shake test When all electrical appliances are installed, the insulation resistance shake test should be carried out. During the shake test, all switches, switches, instruments, equipment and power switches on the line should be disconnected first. After the shake test is confirmed to be correct Then perform power transmission test run. 3. Installation of lighting fixtures The installation of fluorescent lamps in the box room is mainly to install a single lamp in the center, and install multiple lamps in a straight line. The deviation is within 50mm. For fluorescent lamps with hanging chains, the hanging chains and the lamp tubes are perpendicular to each other. Wherein the suspension couplets are parallel to each other. Installation of other lamps: According to the dimensions and installation position of the lamps, securely fix the lamps, and wrap the thread ends tightly against the ceiling without being exposed. 4. Installation of distribution boxes and cabinets The installation positions of distribution boxes and control boxes should be arranged according to the requirements of use. Before installation, ensure that the components of the boxes and cabinets are complete, the openings of the boxes are suitable, and the cuts are neat. The concealed distribution box cover should be close to the wall. The hanging box should be vertical and the elevation should be accurate. The zero line is connected by the bus bar, without splicing phenomenon, the inside and outside of the box is clean after painting, the box cover and switch are flexible, the circuit number is clear, the wiring is neat, and the PE line is obviously installed firmly. For the installation of the power distribution cabinet, first adjust the position and fix it according to the marked position. 5. The installation of the lightning protection grounding system adopts the TN-S comprehensive grounding form, and a special PE grounding wire is provided. Construction material requirements: All metal components of the lightning protection grounding system must be galvanized, and the zinc layer is uniform, without rust and peeling of the zinc layer. The materials used in the project must have a certificate of conformity and be used after being inspected by on-site supervisors and technicians.
