The main cause of lawn lamp malfunction

1. Poor construction quality

Because the construction quality caused by the fault accounted for a large proportion. The main performance: one is that the depth of the cable trench is not enough, the sand cover brick is not according to the standard construction; Second, the production and installation of the aisle tube do not meet the requirements, the two ends are not made according to the standard splitter; Third, when the paving cable dragging on the ground; Four is the foundation of the embedded pipe not according to the standard requirements of construction, mainly is the embedded pipe is too small, plus a certain degree of bending, it is very difficult to go through the cable, "dead bending" at the bottom of the foundation; Fifth, the wire nose compression and insulation wrap thickness is not enough, after a long run will be interphase short circuit.

2. Materials are not qualified

In recent years from the handling of the fault situation, the material quality is also a big factor. The main performance is: less aluminum wire, wire is relatively hard, thin insulation layer. This has been more common in recent years.

3. The quality of supporting projects is not excellent

Lawn light cables are generally laid on the green belt. Pavement construction quality is poor, the ground subsidence, cable stress deformation, resulting in cable armoring. In particular, northeast China is located in the alpine zone. When winter comes, the cable and soil form a whole. Once the ground subsidence occurs, it will be pulled at the bottom of the lawn lamp foundation.

4. Unreasonable design

One is overload. With the continuous development of city construction, lawn lamp also extends continuously, the new lawn lamp often near which lawn lamp, which received circuit, combined with the advertising career developing rapidly in recent years, advertising load were corresponding pick up on the lawn lamp, lawn lamp load is too large, cable line nose overheating, heat, insulation, a grounding short circuit, and so on and so forth; The other hand is, the oneself circumstance that considers lamppost only when lamppost is designed, ignore the space of cable head, after cable head pack is wrapped, majority is to connect a door to all close not, sometimes cable length is insufficient, joint makes do not accord with a requirement, this also is the factor that causes trouble.
