- Q:Decoration doubt, what kind of wall can not open the horizontal groove?
- Power board problem cost 10 less than the general maintenance received you 150
- Q:Apple 6 Charging Why always show this cable has not yet been certified
- 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 to distinguish how many pairs of cable with a large heat shrink tubing
- Yellow line is video, red and white are audio, you can only pick one!
- Q:7 kilowatts of electricity with what specifications of the wire
- 7 kilowatts of electricity with what specifications of the wire if it is single-phase 220V, then 7 kilowatts of current is 7000 × 220V = 31.8A, check the electrical manual 4 square copper wire interception is 33A, to meet the requirements.
- Q:Is the cable head made of every building?
- First, the cable production and installation of each building has. Second, the cable terminal set of waterproof, stress control, shielding, insulation in one, with good electrical and mechanical properties, in a variety of harsh environmental conditions for long-term use. With the advantages of light weight, easy installation and so on. Cable terminal is widely used in electric power, petrochemical, metallurgy, railway ports and construction and other fields. Third, the production process: including the following: . cut off the excess cable; . the cable protective layer of the stripping; . conductor connection; . wrapped around insulation (or shrink pipe); . install the connector shell; . ; . for sealing treatment.
- Q:25 square copper cable how much money one meter?
- Copper should be more than 2.7 flat. Aluminum to 4.5 or more.
- Q:How to solve the computer connected to the TV audio problem, how to set the computer and TV audio separation
- 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: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 25mm² copper cable 35mm² 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 = 1558mm² aluminum cable S = PL / CS = U06 / 46X5 = / 230 = 2307mm² 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 (mm²) (quoted from "electrical entrance permit test low pressure Class theory "" electrical engineering basis ")
- Q: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
- Q:What is the type of pipe that is marked as KBG pipe?
- If no color distinction, 100 meters after you know which line of the fire line which line? The
