With the development of landscape light, the service life of landscape lights can be very long. If the landscape light break down during use, there are four main reasons.
1. Poor construction quality
Faults caused by construction quality account for a large proportion. The main manifestations are as follows: first, the depth of cable trench is not enough and the paving of sand cover bricks is not carried out according to the standard; Second, the manufacture and installation of corridor tubes do not meet the requirements, and the ends are not made into mouthwash according to the standard. Third, when laying cables, they are dragged on the ground. Fourth, the embedded pipe of the foundation is not constructed according to the standard requirements, mainly because the embedded pipe is too thin and has a certain degree of bending, which makes it quite difficult to pass through the cable. The landscape light manufacturer has “dead bending” at the bottom of the foundation. Fifth, the thickness of wire nose crimping and insulation wrapping is not enough, which will cause interphase short circuit after long-term operation.
2. The materials do not pass the test.
Judging from the faults handled in recent years, the low quality of materials is also a big factor. The main manifestations are: the wires contain less aluminum, the wires are relatively hard, and the insulation layer is thin. This kind of situation is more common in recent years.
3, supporting engineering quality but hard
Landscape light cables are usually laid on sidewalks. Poor pavement construction quality and subsidence of the ground make the cable deformed under stress, resulting in cable armouring. In particular, the northeast region is located in a high and cold region. When winter comes, the cable and soil will form a whole. Once the ground subsides, it will be strained at the bottom of the landscape light foundation, and when there is much rain in summer, it will burn off at the foundation root.
4. unreasonable design
On the one hand, it is overload operation. With the continuous development of urban construction, landscape lights also continue to extend. When new landscape lights are built, they are often connected to the circuit that is close to the landscape light. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected to the landscape lights accordingly, which makes the landscape lights overloaded, cables overheated, insulation reduced, and short circuit to ground etc. On the other hand, when designing the light pole, only the light pole’s own situation is considered, ignoring the space of the cable head. After the cable head is wrapped, most of the doors cannot be closed. Sometimes the cable length is not enough, and the joint fabrication does not meet the requirements. This is also the cause of the failure.
