For the high voltage direct buried cables & more than one cable, would the 600mm min between HV cables be a proper distance?

Assuming you have a 2 conductor or triplex cables then you would need 24"(600mm) between them. If you have individual cables 1 circuit then 190mm needs to be maintained between each conductor

Many thanks for your fast reply. But what would be the distance from cable to the trench side?

The formulas for 2000v-35000v are similar to the 0v-2000v. Could there be a possibility of having handy diagrams for 310.15(C) or are the variables to great? Does anyone know if there is a minimum separation that could handle any situation fo 0v-2000v conductors? Does anyone know of a simple Neher-McGrath equation calculator that can be downloaded for free?
