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: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:Can the main cable be aluminum cable? And explain why, thank you!

Power board problem cost 10 less than the general maintenance received you 150

Q:The difference between nylon balls and geese and ducks

As long as the cable is thick enough, 20 meters of the basic loss can be ignored.

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:How do I ask for cable prices? How many tons is one or more?

As long as the line connected to the corresponding location, that is, audio cable audio and video cable, video cable can be used with the video line.

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!

heat shrinkable casing (MRSG) is a new environmentally friendly halogen-free flame retardant casing, inexpensive products, for wire, cable and wire terminals to provide insulation protection

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: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:What is the meaning of PG + digital markings for electrical wiring?

The best cement and other dry in the closing, because the wet cement contains moisture, can be conductive, dry the probability of conduction less. Pay attention to the wire to maintain integrity, no broken skin, it is best to protect the casing.
