Unearthed cable have more insulation strength as compared
to earthed cable.When fault occure phase to ground volage
is root 3 time the normal phase to ground voltage. so If we
used earthed cable It may be chances of insulation puncture.
SO unearthed cable are used.Such type of cable are used in
6.6 KV system where resistance type earthing are used.
