IEC voltage ratings for cables

IEC voltage ratings for cables

(OP)
Can anyone tell me, or direct me to info on, IEC cable voltage ratings?  I've seen IEC cables rated 6/10(12) kV.  What do these numbers refer to?  And how does it relate to the North American 100%/133% ratings?  The first number*SQRT(3) equals the second.  But what is the number in ()?  And how does this apply to single core cables?
