The main reason for the failure of solar lawn lights
1. Poor construction quality
Solar lawn lights account for a large proportion of faults caused by construction quality. Main manifestations: First, the depth is not enough, and the construction of the sand-covered bricks is not carried out according to the standard; the second is that the production and installation of the aisle pipe do not meet the requirements; the third is that the embedded pipe of the foundation is not constructed according to the standard, mainly because the embedded pipe is too thin. Coupled with a certain degree of curvature, it is quite difficult to thread the cable, and "dead bends" appear at the bottom of the foundation; fifth, the thickness of the wire nose crimping and insulation wrap is not enough, and it will short-circuit after a long time.
2. The materials are not good enough
Judging from the failures dealt with in recent years, the low quality of solar lawn lamp materials is also a big factor. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is thin. This situation has become more common in recent years.
3. The quality of supporting projects is not too hard
Solar lawn lights are generally laid on the green belt. The construction quality of the sidewalk is poor, and the ground sinks, which causes the cable to be deformed by force, resulting in cable armoring. Especially in the northeast region, which is located in the high cold zone, the winter comes, so that the cables and the soil form a whole. Once the ground subsides, it will be strained at the bottom of the lawn lamp foundation, and in the summer when there is a lot of rain, it will burn at the foundation root.
4. Unreasonable design
One aspect is overload operation. With the continuous development of urban construction, solar lawn lights continue to extend. When new lawn lights are built, they are often close to which lawn lamp is connected to which circuit. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected accordingly. On the lawn lamp, the load of the lawn lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is reduced, and the grounding short circuit occurs; on the other hand, the pole design only considers the situation of the pole itself, ignoring the space of the cable head After the cable heads are wrapped, most of them cannot even close the door. Sometimes the cable length is not enough and the joints do not meet the requirements. This is also the cause of the failure.
