What are the minimum acceptable insulation resistances of
insulation of underground cable suitable for 0.440kV,11kV,
33kV and 66kV?
Answer Posted / emmanuel
Thumb rule for IR value of a cable as we all know in (rated
KV +1)M ohm . Thus for XKV cable the reated inulation
resistance value is ( X kv +1) Mohm
