Cable tray size must be double of the cable diameter.for
example, three cables(4c/95sqmm,4c/70sqmm,4c/50sqmm)are
traveling in a corridor,...the diameter of
95sqmm-41.7mm,70sqmm-37.7,50sqmm-32. then the total diameter
of the cables are 111.4. for this total diameter, the size
of the cable tray should be double of the total
diameter,.i.e 225mm cable tray can be use.

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
