This Standard specifies requirements for non-draining mass-impregnated paper insulated and lead alloy sheathed cables for working voltage up to and including 19/33 (36) 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. NOTES: 1 Recommendations for selection and operation are given in Appendix A and those for installation are given in Appendix B. 2 Purchasing guidelines are provided in Appendix C. The following cables are included in this Standard: (a) 0.6/1 (1.2) kV four-core. (b) 3.8/6.6 (7.2) kV single-core and three-core belted construction. (c) 6.35/11 (12) and 11/11 (12) kV single-core and three-core belted or screened construction. (d) 12.7/22 (24) kV and 19/33 (36) kV single-core and three-core screened or three-core separately leaded (SL).
