Sequence impedances are very important for short circuit studies and also in planning and operational activities of power system. The computation of the sequence impedances is a very important for insulated cable systems mainly in EHV and HV levels. The objective of this paper is to compute the sequence impedances for a chosen 400kV self contained single core underground cable with different layouts for Copper and Aluminium Core .The Phase impedance matrix (3X3) calculated by eliminating sheaths impedances of (6x6) and also its corresponding sequence impedance matrix (3X3).
