City circuit lamp

1. The installation and operation procedures are complicated. Cables are required to laid cables, and a large amount of basic projects such as excavation, laying dark pipes, interior threads, and filling in the cable sulcus must be carried out. For long -term installation and debugging, the terrain and lines require complex, labor and auxiliary materials are expensive.

2. The electricity cost is high, and the main configuration should be maintained or replaced for the long -term uninterrupted lines and other configurations, and the maintenance cost will increase year by year.

3. There are hidden safety hazards. Due to the quality of construction, the reconstruction of the landscape engineering, the aging of materials, the abnormal power supply, the conflict between the water and electrical pipeline, many hidden safety hazards have been brought about.

4. The average service life of the city circuit light is about 10,000 hours. In addition, the longer the use period, the greater the aging pipeline.

5. The larger the scale, the higher the cost of the city's circuit lamp installation. The total investment will be higher than that of solar street lights. In addition, the cables are stolen each year.
