What is the weight of 500mcm thhn insulated copper cable per foot?
The weight of 500MCM THHN insulated copper cable is approximately 1.002 pounds per foot.
What sized of copper cable to replaced 240 square millimeter cable?
Copper is a better conductor by weight, but aluminum is better by weight, so the copper will be thinner but heavier. You will see that a 250 kcmil aluminium wire will get you 170 amps at 60 degC while a 000 (or 3/0) copper wire will get you 165 amps at 60 degC. I think you mean circular mils, not square millimeters.

If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
To find the percentage of copper-63 atoms in the sample, first add the number of copper-63 and copper-65 atoms together (1.76E4 + 7.88E3). Then, divide the number of copper-63 atoms by the total number of atoms and multiply by 100 to get the percentage. In this case, the percentage of copper-63 atoms in the sample is approximately 69.0%.
How to calculate cable conductor weight?
Basic calculation is: no. of cores x cross-section of one core x 9,6 = copper weight in kg/km e.g. copper weight for cable 4x2,5 = 4 x 2,5 x 9,6 = 96 kg/km This is how cable manufacturers calculate the copper weight. Pls notice that it's valid formula only for cables without screening/shielding. If you know cross-section of screening, you can add that to the formula.
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.
Why is the atomic mass of copper not exactly equal to 64 midway between the mass numbers of copper-63 and copper-65?
Because copper has isotopes. All Copper atoms have exactly the same number of protons, but not all of them have the same number of neutrons. The ones with different numbers of neutrons are known as isotopes. A given sample of Copper will contain various amounts of each of its isotopes. The atomic mass (weight) is an average weight, based on the percentages of the isotopes
What is copper 63?
Copper-63 is an isotope of copper with 29 protons and 34 neutrons. It is a stable isotope of copper found in trace amounts in nature. Copper-63 is used in various applications, including in nuclear medicine and scientific research.
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.
The relative percentage abundance of the two isotope of copper?
Copper has two stable isotopes, copper-63 and copper-65. The relative percentage abundance of these isotopes is approximately 69.17% for copper-63 and 30.83% for copper-65.
How do you calculate weight of copper in 50mm square core size of cable?
