What would be the cable size (XLPE) to supply 256 amp at 11
kv? Air or surrounding Temperature is 32 degree C. Cable
will go under ground at 2.5 feet depth. Group Rating Factors
is 3 cables. Clearance between cables is 7 cm. Soil
Temperature (Ambient) 28o C Soil Thermal Resistivity is 1.2
K.m/W
I would like to use 3 separate single core instead of using
3 core cable.
Some says I should use three separate single core 120RM cables.
Some says 70RM .some says 95.
I m totally confused.
Is there ant specific rule to determine cable size?
