The problem of road monitoring and power supply in an industrial park is about 10 km long. What cable should I use to get electricity from the management Committee?

If it is only an infrared plug, three-phase electricity is not needed, because the infrared plug uses direct current and needs to be connected with a transformer after conversion. If it is a pin or ball machine with a tripod head, it needs three-phase electricity, mainly connecting the ground wire to the circuit board (decoder) that controls rotation. The electricity can be obtained from the main cable of the street lamp nearby, which is low in cost, but it needs to be coordinated with the public lighting management department of the industrial park. If unified power supply is needed, two methods can be adopted. One is wind power plus solar energy plus batteries. It is estimated that the equipment cost is about 8000- 10000 yuan per probe, and the labor cost needs to be calculated separately. The second is to lay the cable by yourself, and the labor cost is very high, mainly the labor cost of trenching (or cable overhead). MMJ3× 10 power cable is selected as the cable, which is too expensive. It is suggested that the first two methods are more reasonable.
