1*400 mm^2 copper conductor. You have to check your conditions if it is underground [earth thermal resistance, distances between cables or ducts, depth and other].It will be better if you will consult a specialist.
An overhead transmission line it will be preferable [it is cheaper!].
RE: Cable size
If you are in AIS, you can use an OHTL, will be about 8-10 times cheaper than a cable.
RE: Cable size
Size should be 2 nos. of 400 sq.mm copper conductor (considering cable derating also) and based on 130 MW (710 Amps), length 500 M.
