A three phase, 11 KV, underground cable system, consider a single core of conductor radius 0.5 cm diameter and lead sheath of 1.25 cm. The core and lead sheath have been separated by two intersheaths with radius 0.75 cm and 1 cm. Draw the cable core, dielectric and intersheath layers showing the thickness of each layer, then determine the voltages on the both intersheaths. Suppose the maximum stress on the layers are the same.
