Mains street lamp of the following disadvantages: first: in mains lighting engineering has complex working procedures, the first thing to laying cable, it will be conducted in cable trench excavation, laying of drainage tubes, pipe threading, such as large backfill foundation engineering, and then for a long time
the lights mains the following disadvantages: first:
in the mains lighting engineering has a complex operating procedure, the first thing to laying cable, the cable trench 【 be In cable trench is to change electric power or telecommunications cable laying and facilities of the underground pipeline, palisade structure is also been laying cable facilities, such as rectangle, circle, arched pipeline structure. 】 Excavation, laid drainage tubes, pipe threading, such as large backfill foundation engineering, and then for a long time of installation and debugging, if any route has a problem, to rework large area, and complex topography and wiring requirements, the cost of labor and auxiliary materials is high.
2: grid lamp alteration due to the construction quality, landscape engineering, material aging, power supply, gas pipeline conflict influences many aspects such as safety hidden trouble.
the third: fixed mains street lamp work has high electricity bills, and be a long-term continuous to maintenance and replacement of lines and other configuration, maintenance costs will increase year by year.
