How many square aluminum wires are needed for a 10kW motor 200m away from the transformer I want to connect three-phase power. The distance between my place and the transformer is 220 meters. How many flat aluminum wires are suitable? Can I buy a 10 flat aluminum wire with leather, a 10 kW motor

How many square aluminum wires are needed for a 10kW motor 200m away from the transformer I want to connect three-phase power. The distance between my place and the transformer is 220 meters. How many flat aluminum wires are suitable? Can I buy a 10 flat aluminum wire with leather, a 10 kW motor


Estimate the line voltage loss Δ U% at the end of load
Simple calculation of voltage loss of 380 / 220 V distribution line
ΔU%=M÷(C×S)
M-total load moment (kW &; m),
S-conductor section (mm2),
C - calculation coefficient of voltage loss, three-phase four wire, copper conductor, C = 70, aluminum conductor, C = 41.6
(quoted from 280 cases of electrical calculation application, P.46)
M=P×L
P-load power (kw)
L-conductor length (m)
For example, l = 220, P = 10,
M=220×10=2200
S=10
Aluminum conductor, C = 41.6
The line voltage loss Δ U% = 5.3 is obtained
If it is required that Δ U% is not more than 7, 10 square aluminum wires can be used,
If Δ U% is not more than 5, aluminum wire with S = 16 square can be selected



What is the maximum load of 25 square aluminum wire 500 meters away?
They used 50 square aluminum wires to pull 200 meters away from the transformer. I want to connect electricity from them. I'm 500 meters away from them. Can I take two 16 kW motors with 25 square aluminum wires? (three-phase four wire)


Three phase four wire, two 16 kW motors, total power: 32kw, total working current: 61A
200 meters away, the minimum selection of aluminum conductor area of 50 square mm
I don't know what the load of the other company is. If it's more than 10kW, the aluminum wire of the other company's 50mm2 is also less. It's 700m from the transformer to your home, so we should also consider the power consumption of the other company
