Write any FIVE (5) criteria of underground cables that must befulfilled in electrical transmission. (5 marks) Consider the FigureQ5 (d). Consider a very small layer of insulation of thickness dxat a radius x. The insulation resistance (R) of a single-core cableis 495 MΩ per kilometer. The core diameter is 2·5 cm andresistivity of insulation (ρ) is 4·5 × 1014 Ω-cm. r1 and r2 referconductor radius and internal sheath radius, respectively. Find theinsulation thickness
