Cross the street lamp1

Now the construction of urbanization, many village building development, and community is often used in modelling rich garden light, therefore the courtyard lamp sales soar. But garden light but not in the installation specification, courtyard lamp manufacturers today small make up take you to understand the courtyard

today, with the development of urbanization and construction of many residential buildings, shape rich garden light is often used in residential area, so the courtyard lamp sales surge. However, courtyard lamp installation and construction is not standardized. Today, courtyard lamp manufacturer's small staff will show you the garden light some common problems in installation and construction. 1. Construction quality defects caused by the poor quality of construction accounted for a significant proportion. Main show is: one is the cable trench depth is not enough, sandbags brick laid not according to the standard; Second, the corridor pipe manufacture and installation does not conform to the requirements, end not made in accordance with the standard mouthwash. Third, when laying cable, they dragged on the ground. Fourth, not according to standards based embedded pipe construction. Too thin, the main reason is that embedded pipe bending to a certain extent, it is difficult to through the cable. & other appear at the bottom of the base. Dead corner. The situation; Fifth, thread and pressure to the thickness of the insulation package is not enough, and run for a long time can cause a short circuit. 2. The material didn't pass the test. From the perspective of the failure of treatment in recent years, low material quality is also an important factor. Main show is: less wire aluminum content, lead a hard, thin insulating layer. This kind of situation is more common in recent years. 3 supporting engineering quality closes nevertheless, courtyard lighting cables are usually laid on the sidewalk. Poor quality of pavement construction, the ground sinks, the cable force deformation, lead to cable armoring. Especially in cold area in northeast China. When winter comes, cable and soil will form a whole. Once the ground sinks, it will be at the bottom of the garden lamp base is taut, and when there are a lot of rain in summer, it will be burned in basic root. 4. Unreasonable design on the one hand, it is overload operation. With the continuous development of city construction, garden lamp has been extended. When a new garden light is built, it is normally connected to the circuit near the garden light. In addition, with the rapid development of advertising in recent years, advertising on the load is connected to the courtyard lamp accordingly, which makes the garden light overload, cable overheat, thread and reduced overheating, insulated grounding short circuit. On the other hand, when designing light pole, only consider their own light pole, ignore the empty space of cable head. After winding cable head, most of the door can't close. Sometimes the cable length is not enough, joint production does not conform to the requirements. This is also the cause of the failure.
