    Leave the cable type and size and everything else to your Electrician.

    36 amps load current per phase so go from there.
    I've no idea the ccc of sy as it's not recognised in bs7671 as it's classed as a non British standard cable But most manufacturers claim it's to bs en 50525-2-11

    SY is unlikely to be the most suitable cable for the job.
    Presumably you don't mean 25kV but 25kVA?
