Question

A single core cable of conductor diameter 2.5 cm and lead sheath of diameter 5.6 cm is to be used on a 66 kV, Phase system. Two intersheaths of diameter 3.3 cm and 4.5 cm are introduced between the core and lead sheath. If the maximum stress in the layers is the same, find the voltage on the intersheaths.​

Answer 1
