(i) Conductors: Each core consists of a single copper/aluminum metal and allows the passage of electricity.
(ii) Insulator: The insulation between the cores is magnesium oxide a material capable of withstanding high temperature but absorbent to moisture.
(iii) Outersheath: Is a seamless copper/aluminium tube. The sheath is sufficiently pliable to withstand bending operations during cable installations. It serves as earth continuity conductor.
