WebFor these reasons, intersheath grading is rarely used. Example 11.15. A single core cable of conductor diameter 2 cm and lead sheath of diameter 5.3 cm is to be used on a 66 kV, 3-phase system. Two intersheaths of diameter 3·1 cm and 4·2 cm are introduced between the core and lead sheath. Web5.3.1 Cable Grading for Uniform Stress Distribution The electric stress in the dielectric may be more equally distributed by one of the two following methods. (i) Capacitance grading (ii) Intersheath grading 5.3.2 Capacitance Grading In this method of grading, the insulation material consists of various layers having different permittivities.
