FAQ

Is the cable head made of every building?

Building in accordance with the floor or unit configuration distribution box, there are office buildings using a total box. Where there is a cable out of the situation, must be wrapped to make the cable head, according to the choice of distribution box circuit breaker wiring crimp or not crimp the cable terminal. In other words, the cable head must be made, but not necessarily crimp the cable terminal.

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.

5 air conditioning can be used 4 square cable

Lengthened low voltage side, the line resistance increases, the voltage drop increases. Reduced load capacity. So that the router due to insufficient supply voltage and can not work properly. It is not allowed to use 9V power supply. Voltage is too high, the router part of the internal power supply increased power, heat increased, it is possible to burn the router. It is necessary to extend the power cord, I suggest you extend the power supply side (220V one end) safe and reliable. Increase the voltage to increase the supply current, in the electrical working voltage range (with the electrical work voltage range) is allowed, too low electrical appliances can not work properly. Too high there is the risk of burning appliances, according to your actual situation, marked 5V0.2A that the router works at rated voltage, so the way to improve the supply voltage is not applicable. So you can only improve the power supply power (that is, you say to increase the power supply current rather than voltage). With the reserve power, it will provide enough current at the rated voltage (the router as a resistor, from I = U / R, you can know the danger of increasing the voltage) need help please message

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

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

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 ")

How much of the cable with the switch?

The switch is not selected according to the cable and is selected according to the current. The cable is determined by the size of the power (converted to current) and the distance from which the distance is far. The greater the power distance, the greater the cross-sectional area of the required cable. For example: 15KW motor selection cable current I = P / 1.732UcosΦ = 15 / 1.732 / 0.38 / 0.8 = 28A if it is close (within tens of meters), copper cable 6 square millimeters, aluminum cable 10 square millimeters. If it is in the distance (a few hundred meters), copper cable 10 square millimeters, aluminum cable 16 square millimeters. If it is long distance (close to kilometers), copper cable 16 square millimeters, aluminum cable 25 square millimeters. The switch is regardless of distance, completely based on the load current to choose, generally according to the load current of 1.5 times to 2 times to choose.
