About wire size calculation

I have to calculate size of a wire for a solar pump. The pump is 3 phase with ratings 415 V and 3.5A current of 1.5 kW. The cable length is 190 meter. Can anyone give me the calculation of the size of the cable that i needed. I am planning to use 3 core cable may be submersible.

You would want the volt drop to be under 3%, using a volt drop calculator a wire size or 2.5 square mm. would be required. Always follow local code requirements applicable.
