1. Poor construction quality The proportion of failures caused by construction quality is large. Main performances: First, the depth of the cable trench is not enough, the sand-covered bricks are not constructed according to the standard; the second is that the production and installation of the aisle tubes do not meet the requirements, the two ends are not made according to the standard; the third is when paving the cable The fourth pre-buried pipe is not constructed according to the standard requirements, mainly because the pre-buried pipe is too thin, plus a certain degree of camber, it is quite difficult to wear the cable, and there is a "dead bend" at the bottom of the foundation; The wire nose crimping and insulation wrap are not thick enough, and after a long period of operation, the phases are short-circuited. 2, the material is not off Judging from the fault conditions handled in recent years, there are also many factors in the low quality of materials. The main performance is: the wire contains less aluminum, the wire is harder, and the insulation layer is thin. This situation has been more common in recent years. 3, the quality of supporting projects is not too hard The courtyard light cable is usually laid on the sidewalk. The construction quality of the sidewalk is poor, the ground sinks, and the cable is deformed by force, resulting in cable armoring. In particular, the northeastern region is in a cold zone, and the arrival of winter makes the cable and the soil form a whole. Once the ground subsides, it will be strained at the bottom of the Garden Lamp base, and when the rainwater is too much in summer, it will be blown at the base root. 4, the design is not reasonable On the one hand, it is overloaded. With the continuous development of urban construction, the garden lights are also constantly extended. When the garden lights are newly built, which circuit lights are close to each other, which circuit is received, and in recent years, the advertising industry has developed rapidly, and the advertising load is also connected to the courtyard. On the lamp, the load of the garden lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is lowered, and the grounding is short-circuited; on the other hand, the lamp post is designed only considering the condition of the lamp post, ignoring the space of the cable head, After the cable head is wrapped, most of the doors are not closed, sometimes the cable length is not enough, and the joint production does not meet the requirements, which is also a factor causing the failure.
LED wash wall lamp, as the name implies, let the light like water wash the wall, mainly used for building decoration lighting, and also used to outline the large buildings.Since LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, the washing wall lamp of other light sources is gradually replaced by LED washing wall lamp in 2013.
