This Standard specifies requirements for non-draining mass-impregnated paper insulated and lead alloy sheathed cables for working voltages up to and including 19/33 kV. Provision is made for extruded or lapped non-metallic protective coverings over the lead alloy sheath, with or without galvanized steel wire armour. Some typical constructions are shown in Figure 1.NOTE: Recommendations for selection and operation are given in Appendix A and those for installation are given in Appendix B.The following cables are included in this Standard:(a) 0.6/1 kV single-core, two-core, three-core and four-core.(b) 1.9/3.3 kV and 3.8/6.6 kV single-core and three-core belted construction.(c) 6.35/11 and 11/11 kV single-core and three-core belted or screened construction.(d) 12.7/22 kV and 19/33 kV single-core and three-core screened or three-core separately leaded (SL).
