Landscape light installation method and requirements solar street light-litelsolar manufacturer

1. Laying of electric wire pipes and steel pipes: (1) The design and selection of electric wire pipes and steel pipes shall be concealed. , switch boxes, etc. must have product certification. (2) The pre-embedded pipes should be closely coordinated with the civil construction. First, the arrangement of the water pipes should be satisfied, and then the electrical piping should be arranged according to the position. (3) The outdoor power distribution line shall be laid underground with cables through HDPE pipes. The pipelines shall be buried with a depth of 0.7m, and shall not be less than 0.5m when crossing the water system, and shall be laid with steel pipes when crossing the motor vehicle lane. When the garden light line encounters a branch, a L500.W300.H700 passage well shall be set up next to the garden light. Reliable waterproof measures should be taken for all line branches (such as the use of IP62 waterproof junction boxes). 2. Threading: Threading inside the pipe must strictly control the incoming wire. The specification and model of the wire must meet the design requirements and have a factory certificate. After arrival, check whether the insulation resistance, core diameter, material and weight of each coil meet the requirements. The mouth guard of the corresponding specification should be selected according to the size of the pipe diameter, and the specifications and materials such as nylon pressure cap and wiring nose should meet the requirements. Threading in the pipe should be carried out after the building structure and civil construction work is completed. First thread the wire, use Φ1.2~2.0MM iron wire, leave a margin of 10~15CM at both ends, and then clean the soil of the pipe, switch box, socket box, etc. ,dust. When threading, pay attention to the fact that the wires of the same AC circuit must be threaded into the same tube, and the wires of different circuits, different voltages, and AC and straight lines shall not be threaded into the same tube, except for the following situations: circuits with a standard voltage below 50V; the same equipment or The power circuit of the same assembly line equipment and the control circuit without special anti-interference requirements; several circuits of the same lantern; several circuits of the same lighting, but the total number of pipes in the pipe should not be more than 8. The reserved length of the wire: 15CM for the junction box, switch box, socket box and lamp head box, and 1/2 of the perimeter of the box in the distribution box. 3. Lamp installation: (1) Lamps and light sources are used according to the design requirements. All lamps should have product qualification certificates. The wiring inside the lamps is strictly prohibited from being exposed, and the lamps and lanterns are complete. (2) Check whether the lamps meet the requirements according to the installation site, and check the wiring inside the lamps. The installation of lamps must be firm, in the correct position, neat and beautiful, and the wiring is correct. Lamps above 3KG must be pre-magnesium hooks or bolts, and the metal shell of lamps below 2.4M should be grounded. (3) After the installation is completed, the insulation resistance of each branch circuit is qualified, and the power-on operation is allowed. After the power is turned on, it should be carefully checked whether the control of the lamps is flexible, prepared, and the switch corresponds to the control sequence of the lamps. Fourth, grounding protection and safety measures: (1) The grounding protection adopts the TT method, and a closed-loop artificial grounding device is set around the outdoor lighting box. The grounding electrode adopts 50*50*5 L2500 hot-dip galvanized angle steel, and the connecting wire adopts 40*4 Hot-dip galvanized flat steel, the grounding electrode spacing is 5m, the buried depth is 0.8m, and the grounding resistance is not more than 10 ohms. (2) The ground terminals of all lamps in the system are reliably connected to the PE busbar of the lighting box after being reliably connected with the PE wire and grounded. (3) In order to prevent lightning strike and overvoltage, a first-level surge protector is installed in the outdoor lighting box. Yangzhou Global Solar Technology Development Co., Ltd. focuses on the production and research and development of solar road lighting, integrates the practice and application of current intelligent lighting systems, and truly is an enterprise worthy of the name of Internet + road lighting.
