resistivity of epoxy

pls i want to know the resistivity of the epoxy and if this value depend on the thickness layer of the epoxy. as this value may help me
in the calcultion and design for earthing for hv substation

Many types of filler, which is probably more relevant.

If you use silver as the filler, the resistivity is very low (i.e. conductive epoxy). If you use a nonconducting filler, the resistivity of the epoxy is very high. Just about anything between a very good conductor and a very good insulator is possible. So you'll need a bit more information than simply "epoxy" to get an estimate of its resistivity.
