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: 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.

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?: 1 Definitions and basic tasks Communication lines and ancillary facilities Routine inspection operations are based on regional characteristics of regular light cable line inspection and protection line publicity, timely detection of problems, troubleshooting factors to ensure smooth communication; communication lines and ancillary equipment to make up Strong, to ensure that the optical cable lines and ancillary equipment integrity is good to prevent the occurrence of failure

Q: 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.

Q: Does anyone know the "line buckle" classification (including shape / size / material / has been some commonly used size!) Line deduction is a hardware products! For daily necessities!: If you want to ensure that the transmission medium does not cause the signal to cause attenuation and interference, fiber transmission or balanced cable transmission is the best solution. If you need fiber transmission, the cost is high because you need to buy digital fiber converters and digital audio decoders and related equipment, but this can be to the maximum extent to ensure the integrity of the signal and the smallest noise interference. If you want to use low-cost transmission can also be used directly to the cable transmission, but must use a balanced interface for transmission, and with 2-core shield or 3-core, 5-core shielded cable for transmission. This can also ensure the clarity of the signal to the maximum extent, but do not eat hungry thirsty 丨 Chicken check blood sausage is too long. No matter how good the cable will be attenuated, the size of the attenuation will directly affect the signal quality and signal integrity. So the transmission distance with the balance line can not be too far. More than two kinds of transmission methods than the existing single-line transmission is much better, if you are a fever-level players, I suggest you use fiber transmission. But if your power amplifier or your source signal to noise ratio is not high, I do not recommend you use fiber transmission, because even if the quality of fiber transmission no matter how good your source is not high, then it does not make sense The

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: The difference between nylon balls and geese and ducks: If the 2.5 square copper wire for the output extension cable, 20 meters distance, the total resistance of about 2 * 1.7 * 0.2 / 2.5 = 0.272 (ohms), the current maximum 1.8A, the voltage drop is 0.272 * 1.8 = ), The charging voltage is 55-0.5 = 54.5 (volts), a difference of about 1% will not have any impact on the battery. However, the third floor, said Ye Hao, you can put the charger put the debris room, from your house put a 220V power cord down, home and then engage in a switch control. It is best to design a light at home, can intuitively see if the electricity is full. That's better. Design light, teach you a way: to find a bad leakless protector, open there is a coil-like ring-shaped stuff, called zero sequence current transformer, it will be down, be careful, do not put Transformers inside the coil hurt, get down, in the transformer two thin lines connected to a light-emitting diode. And then your 220V power cord line of fire from the center of the sensor through, around 3-5 turns. In this way, as long as there is current flow, the light-emitting diode will be bright, when the charge is over, the charging current is close to zero, the light-emitting diode will be extinguished. You can from the light-emitting diode is lit to determine whether the electric has been filled. I also have an electric bike that is so charged.

Q: How do I ask for cable prices? How many tons is one or more?: Yellow line is video, red and white are audio, you can only pick one!

Q: 6 square cable up to how many air conditioning (1.5P): If it is connected to the 220V of the electricity above the 6 square of the copper line can be
