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 much of the cable with the switch?
Switch = (2-2.5) current three-phase current = P / 1.732 / 0.38 / 0.8 single-phase current = P / 0.22 / 0.8
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:Apple 6 Charging Why always show this cable has not yet been certified
Motherboard and power supply problem, the best way is to try to USB2.0 ban on the use of USB1.1 but will be slower
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:7 kilowatts of electricity with what specifications of the wire
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.
Q:What is the type of pipe that is marked as KBG pipe?
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:25 square copper cable how much money one meter?
Copper should be more than 2.7 flat. Aluminum to 4.5 or more.
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:How to distinguish how many pairs of cable with a large heat shrink tubing
Cable bridge grounding should belong to the protective grounding, grounding resistance at a cross point is not greater than 50 milliohms, no jumper no more than 5 milliohms
