The main reasons for the failure of solar garden lights

There are several main reasons for the failure of solar garden lights: 1. Poor construction quality The failure caused by construction quality accounts for a large proportion. Main manifestations: First, the depth of the cable trench is not enough, and the sand laying bricks are not constructed according to the standard; second, the production and installation of the aisle pipe does not meet the requirements, and the two ends are not made into bell mouths according to the standard; third, when laying cables Dragging on the ground; Fourth, the pre-embedded pipe of the foundation is not constructed according to the standard requirements, mainly because the pre-embedded pipe is too thin, and coupled with a certain curvature, it is quite difficult to pass the cable, and there is a dead bend at the bottom of the foundation; Fifth, the line Insufficient thickness of nose crimping and insulation wrap will cause phase-to-phase shorts after prolonged operation. 2. The material is not good enough Judging from the failures of garden lights handled in recent years, the low quality of materials is also a big factor. The main manifestations are: the wire contains less aluminum, the wire is relatively hard, and the insulating layer is thin. This has become more common in recent years. 3. The quality of the supporting projects is not hard. The garden light cables are generally laid on the sidewalk. The sidewalk construction quality is poor, the ground sinks, the cable is deformed by force, and the cable is armored. Especially the northeast region is in the alpine zone. When winter comes, the cable and the soil form a whole. Once the ground subsides, it will be pulled at the bottom of the garden lamp foundation. In summer, when there is a lot of rain, it will burn at the root of the foundation. 4. Unreasonable design On the one hand, it is overloaded. With the continuous development of urban construction, garden lights are also continuously extended. When building new garden lights, whichever garden light is close to is often connected to which circuit. In addition, the advertising business has developed rapidly in recent years, and the load of advertising is also connected to the garden accordingly. On the lamp, the load of the garden lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is reduced, and the grounding short circuit occurs; After the cable head is wrapped, most of them can't even close the door. Sometimes the cable length is not enough, and the joint production does not meet the requirements, which is also the factor that causes the failure.
