shandong street lamp lighting factory co. , LTD. Production of solar garden light and led street lamp is a new kind of energy conservation and environmental protection products, in the modern market. Although they are very expensive, but they do made its contribution to energy saving and environmental protection. If you don't regularly solar garden lamp installation and maintenance, there will be a failure. Today, I'd like to talk with you in the daily life of common causes of solar garden light. 1, the material is not qualified from the perspective of the failure of treatment in recent years, low material quality is also an important factor. Main show is: copper conductor is less, conductor is hard, with thin insulating layer. This kind of situation is more common in recent years. 2. Poor construction quality caused by the installation quality failure accounted for a significant proportion. Mainly manifested in the following points: one is the cable trench depth is not enough, sandbags brick not according to standard construction; 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. 3. 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, the advertising industry has developed rapidly in recent years, advertising load also correspondingly connected to the courtyard lamp, garden light overload, cable overheat, thread reduced overheating, insulation and 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 is not in conformity with the requirements. This is also the cause of the failure. 4 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.
