What size of cable you can use for 3 phase supply with the length of 750 meter and load of 250 amps you will use copper wire please help you?
This information can be found in the latest edition of the NEC. A calculator that I like to use is below in Related Links. Note that the NEC (National Electric Code) tables are usually adopted in the US. Since your question is in SI units (meters), you are probably outside the US. Be aware that your local electrical code may be more stringent than the NEC, or have different requirements. Best to consult a local professional or research what standards are adopted in your area! Be legal, be safe! IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.

What is the size of 3 core copper cable for 3 phase 125 amps current for 10 meter length indoor cable tray?
Allowable ampacities for not more that 3 copper conductors in a cable based on an ambient temperature of 30 degrees C. A #1 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 130 and 140 amps respectively.
Why is a cable on a plug made from copper?
Copper is a very conductive metal and also ductile.
What is CU Cable?
CU Cable is a type of cable commonly used in networking applications to connect devices to a network. It stands for Copper-Clad Aluminum, indicating that the cable is made from a combination of copper and aluminum materials. CU cable is less expensive than pure copper cabling but may not perform as well in high-speed or long-distance applications.
Why copper cable better than aluminium cable?
Copper cable doesn't conduct as well as Aluminum , but for most applications, Copper doesn't heat up as quickly as Aluminum, and is stronger in tensile strength. Also when using Aluminum cable you need to use an oxide to help conduct as Aluminum will work loose from locks in time.
What can copper cable do?
One of the major functions of copper cable is to conduct electricity. It is also quite malleable and can be moulded to many forms. You can also make it very thin for more effective wires.
What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.
What size cable for 50 amps 3 phase for 650 meters length?
70mm 4core copper cable
What is the actual loss of voltage in 100 meter length of cable?
It depends on the material of the cable (aluminum or copper) and the gauge of the cable. (Thickness). And on the current you intend it to carry.
How do you ground a dishwasher with only 2 wires available?
If it has a metal body you attach a suitable cable to match the ground or earth wire colour in your country ( such as a 6 mm squared cross sectional area ) copper cable with green-yellow ( in the U.K.) insulation colours to the metallic frame of the dishwasher with a cable lug and a brass ( preferably ) nut & bolt. Then using a suitable length of cable to the nearest grounded piece of metalwork such as a copper pipe using a "earth clip" for a copper pipe. These can be bought from electrical wholesalers who supply all electricians or / and electrical contractors.
What size in mm of cable on 160amp for 180meter length?
The answer is different depending on the supply voltage because the allowable volt drop is a percentage of the supply voltage.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
What is the size of 3 core copper cable for 3 phase 125 amps current for 10 meter length indoor cable tray?

What is the maximum current capacity of 4 sq mm copper wire?
I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
Copper cable and fiber optic cable are examples of?

What is the function of the power supply cable?
· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.
What machines do you use to recycle copper from scrap cable and copper wire?
I know two kind of machines for copper recycling. One is cable granulator which is used for making copper core into small granules by grinding cable and separating PVC. This is a ideal machine for miscellaneous cable. The other is copper wire stripper which is to strip the PVC cover and you get the entire copper core. This is widely used in various copper wire various diameters.
