How much ampere current can a 10 square aluminum wire bear

There is no exact statement about how many amperes the wire can withstand. The current carrying capacity of the wire through the tube is different from that without the tube. The number of wires through the tube is different, and the current carrying capacity of the wire is also related to the ambient temperature. A 10 square aluminum wire can withstand about 40 amperes

How many kilowatts of power can a 10 square aluminum wire bring? The distance to a large wire is 100 meters
Three 10 square wires 380V

In detail, it depends on the minimum working voltage requirements of your equipment. Let's assume that the main line can stably provide voltage above 380V. If your equipment is allowed to work at a minimum of ± 7%, that is to say, the voltage drop is allowed to 353v, then your 10 square meter aluminum line can withstand 40A at most, that is, 353v * 40A = 14120w, 14kw
If ± 5%, that is to say, the voltage drop is allowed to be 361v, then you can withstand 28a at most on this section of 10 square aluminum wire 100 meters,
361v * 28a = 10108w, 10kW

Three phase motor 7.5kW, distance 100m, how many square aluminum wire

Three phase ordinary motor 7.5kW, rated current about 15A
4 square aluminum wire, safe current carrying capacity about 20A
6 square aluminum wire, safe current carrying capacity about 30A
The distance is 100 meters. If the actual load is very light and the start-up is also completely empty, you can choose 4 square aluminum wires, but note that this is relatively reluctant
It's better not to be less than 6 square meters
The above is the overhead laying, if it is cable or pipe laying, we need to add one level to consider

30 meters away from 35 square meters aluminum three-phase four wire can bear the maximum number of kilowatts

Cables are generally considered to carry current
35m2 aluminum wire, regardless of laying mode, installation environment and other factors
Its current carrying capacity is generally 105a
As for the power to bear, please calculate according to the formula: P = uicos ψ (voltage × current × power factor)
