- Q: 1000 kW 600 m cable to use much
- Such a large load so far away, can only be transported with 10KY, near the installation of the transformer Caixing, if the 380V transmission, cross-sectional area, high cost, loss of large, not worthwhile. 10KV high-pressure delivery, current 55A, with 25mm? copper cable 35mm? aluminum cable delivery on it. If the 380V transmission, according to the line voltage loss simple calculation formula △ U% = PL / CS take △ U% = 5 copper cable S = PL / CS △ U% = 1000X600 / 77X5 = / 385 = 1558mm? aluminum cable S = PL / CS = U06 / 46X5 = / 230 = 2307mm? Line voltage loss △ U Simple calculation formula △ U% = PL / CS △ U% - Percentage of voltage loss P - Active power of conveying (Kw) Distance of L- M) C-constant, aluminum single-phase 8.. aluminum three-phase four-wire 46; copper single-phase 12.. copper three-phase four-wire 77S-conductor cross section (mm?) (quoted from "electrical entrance permit test low pressure Class theory "" electrical engineering basis ")
- Q: What is the meaning of PG + digital markings for electrical wiring?
- If no color distinction, 100 meters after you know which line of the fire line which line? The
- Q: 3 by 16 cable is a few flat? How? That 5 by 16?
- Is the power directly out of the CPU power supply line or on this basis and added the extension line
- Q: How much of the cable with the switch?
- The switch is selected according to the current. General switch = (2-2.5) Current three-phase current = P / 1.732 / 0.38 / 0.8 Single-phase current = P / 0.22 / 0.8
- Q: Can the main cable be aluminum cable? And explain why, thank you!
- Excretion training is the use of positive reinforcement, that is, a variety of food, toys, the best time to reward
- Q: 5 air conditioning can be used 4 square cable
- You do not use the 9V power supply, a long time will burn the router.You'd better measure the original adapter voltage, if you want to extend the power cord, it is best to use a thick line of reliable connection, you can not start now, you can not start Depending on whether the extension line is too thin, causing the voltage drop too much.It is necessary to extend the front end of the adapter can extend the 220V power cord.
- Q: The difference between nylon balls and geese and ducks
- It depends on the thickness of the wires you use. The thicker the copper wire is, the better. Because the distance will be a voltage drop. So be it, you use a multimeter to look at how long you charge when the output voltage is how much. If you can more than 50 should be no problem. If the voltage is relatively low can change a rough wire, or find a few wires in parallel can also be. I do not know if you can understand it. Even if there is a voltage drop if it is not very powerful should not be the problem, the worst result is the battery charge dissatisfaction. You can try to see how the effect of the day. Certainly will not break your equipment and battery, rest assured it
- Q: How do I ask for cable prices? How many tons is one or more?
- Cable bridge grounding should belong to the protective grounding, grounding resistance at a cross point is not greater than 50 milliohms, no jumper no more than 5 milliohms
- Q: 6 square cable up to how many air conditioning (1.5P)
- 1 square millimeters can flow 4A current, 1KW380V, then the current is about P = UI about 2.6A7KW, 380V, then the current is about 18A, each with the line to share 18/3 = 6A2.5 square mm of copper on it. Of the area need to take . probably 6 level. V is probably 7KW220VI = p / u = 7000/220 = 31A. Then need 10 square millimeters of copper.
- Q: 25 square copper cable how much money one meter?
- 3 plus 1 64.13 yuan, 3 plus 2 75 yuan, 4 plus 1 81.38 yuan contact to see my registration name
