We have under ground cables with rated voltage 11kV, and maximum highest voltage is 12 kV buried with sand, the earth in this area has very high humidity.
If I want to make joint for this cable, what should be the specifications of this joint, should I ask for higher insulation voltage(more than 12 kV) to make sure the joint will not fail in future, or the same specifications of the cable 11 – 12 kV is sufficient.
I will appreciate any help.
Thanks in advanced.
