The hotel is 600 meters away from the transformer. The electricity consumption is about 70 kilowatts. How much 3-phase 4-wire aluminum underground wire should be used? How to calculate it? Is there a formula?

The power consumption is about 70 kilowatts, and the working current is about: I=70/(1.732*0.38*0.8)=133A

The aluminum conductor should not be less than: S=133/2 =66.5 square millimeters

According to the wire specification, aluminum conductor 3*71*35 should be used

This seems to be possible, but the power supply radius is generally considered within 500M.

And since you are a hotel, there are many single-phase electrical appliances, such as lighting fixtures.

It is recommended that you use YJLV22-4*120 cable.
