ABSTRACT

At one time, paper insulated lead-covered cables were almost exclusively used for main and submain cables. For cables buried in the ground, lead alloy provides excellent corrosion resistance. However, a range of other cable types is now available, and these include PVC insulated, XLPE insulated and LSF type, usually with wire armouring. Each has characteristics which can be appropriate to a range of installation situations, and some detail is given in the sections which follow.
