Universal Solar analyzes for you what kind of cable is suitable for solar street light-

Recently, common customers have asked such a topic when they are doing the basics of high pole lights. Today, we will give a detailed introduction to the cable. For example, the frame type is 28 meters, 12 and 400 watts. We divide the total number of lights into three parts, and each phase has a Four 400 watts, and the starting current of 400 watt sodium lamps is 7 amps (the starting current of 150W sodium lamps is 2A, the starting current of 250W sodium lamps is 4A, and the starting current of 400W sodium lamps is 7A. The starting current without capacitors is 2A, and there are 1.7~1.8A), then 4*7 amps u003d 28 amps. According to the basic knowledge of wiring (1 square with 6A current), but considering the voltage drop, line damage and backup load, it can be used with 10 square phase lines. The load of high-pole lights is uniform. In the case of uniform three-phase, the zero line can be smaller than the phase line, and a grounding line is required if the customer needs it. This is the so-called three-phase five-wire system! The street lamp wiring method is the same as above. If the customer needs low cost, the single-phase power supply can be used when the power connection right is in Party B, that is, one zero (N) and one fire (L) power supply. If required, a grounding (PE) line should be configured. If a very strict project needs to be set up in the middle of the night and all night lights, then it will be divided into (sub-item control) or (sub-loop control).
