Data of 35kV Cables buried for power collecting in Wind Farm of USA

(OP)
Dear Colleagues.
 I am working in Spain for a spanish Company who promotes, builds and operates Wind Farms and Thermosolar Power Plants.
   In accordance with a possible project in USA of a Wind Farm I have to do some calculations related to drop voltage, power losses in buried cables so I would need to get the following Data:
    In a Pre-study it is indicated the size of cables for interconnection between aerogenerators eachselves ( size 4/0 )  and the JBs of several lines towards the main Substation (1000kcmil ).
     I only have the size of the cable and I want to know the type of cable ( aluminium prefered to copper , type of isolation, standards of fabrication , main manufacturers of cable in USA and the link of their webpages, etc. ).
I have tried to get this information through google with no good results.
   I would like to get too the resistance and reactance of the usual 35kV cables for the above using and with sizes between 4/0 and 1000kcmil - and others superior to the bigger one size-, included the price of these size of cables due to the study that I have to do for my Company will include the optimization of size choice taking into consideration the losses in the 20 years of Wind Farm operation.
   Any additional information, hypotheses, recomendations for Wind Farm Design, standards applicable as well as everything you consider to indicate for helping me will be strongly appreciated.
    Thankyou very much in advance for your cooperation.
        Best Regards

igg1966, the NA does not differ from other parts of the world. Current flows in the same direction so whatever you calculate in Spain is applicable behind the big puddle called Atlantic. The web pages given by others could be a great help as other European cable manufacturers. There are factories of Nexans, Prysmians, Silec/General and many more producing cables in this voltage range all over US.

Good luck.
