What are the common problems in the installation and construction of LED courtyard lights

Nowadays, with the construction of urbanization and the development of many residential buildings, courtyard lamps with rich shapes are often used in residential areas, so the sales of courtyard lamps have soared. However, some courtyard lamps are not standardized in the installation and construction, so let's know what common problems exist in the installation and construction of ED courtyard lamps.

1. Poor construction quality

Because the LED courtyard lamp construction quality caused by the failure accounted for a large proportion. Main performance: first, the depth of cable trench is not enough, and the construction of sand and brick covering is not carried out according to the standard; Second, the embedded pipe of the foundation is not constructed according to the standard requirements, mainly because the embedded pipe is too thin, coupled with a certain curvature, it is quite difficult to pass through the cable, and there is a "dead bend" at the bottom of the foundation; Third, the thickness of the crimping and insulation wrapping of the wire nose is not enough, and the phase to phase short circuit will occur after a long time of operation.

2. Materials fail to pass the test

Judging from the outdoor LED courtyard lamp failures handled in recent years, the low quality of materials also has great factors. The main performance is: the conductor contains less aluminum, the conductor is relatively hard, and the insulation layer is thin. This situation is more common in recent years.

3. The quality of supporting projects is not good

Led courtyard light cables are generally laid on the sidewalk. The construction quality of the sidewalk is poor, and the ground sinks, causing the cable to be stressed and deformed, resulting in cable armor. In particular, the northeast region is located in the alpine zone. The arrival of winter makes the cable and soil form a whole. Once the ground subsides, it will be strained at the bottom of the courtyard lamp foundation, and when there is a lot of rain in summer, it will burn out at the root of the foundation.
