Q: 1000 kW 600 m cable to use much: Three-phase 380V, 1000 kilowatts load, the working current is about: 1899A. The total area of copper cable is not less than: 1200 mm2 copper cable. . the cable is usually a few or several groups of wires (at least two each) twisted from the rope-like cable, each group of wires are insulated from each other, and often around a center twisted, the entire outer package Highly insulated cover. Cable with internal power, external insulation characteristics. . the cable has power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.

Q: Is the cable head made of every building?: Generally have every building floor wiring closet must be connected to the big cable. The big cable comes in to do the cable head

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.

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: 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: 5 air conditioning can be used 4 square cable: Such as the extension line added to the adapter primary (city side) certainly easy to use. Extended by two meters, the router does not start, may be extended wire diameter is too thin, bold wire try. If not, choose 6V2A adapter try, the voltage is too high will burn the router. Increase the current is no problem, just like the computer's power, 300-watt power can be replaced, and small is not OK.

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?: 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: 6 square cable up to how many air conditioning (1.5P): 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: 25 square copper cable how much money one meter?: 3000w electrical work at 220V voltage is about 13.6A (current = power divided by voltage). Copper core line of the working current is generally a square 4-6A. That is to say you use 3-4 square power cord more secure.
