XLPE INSULTED PVC OR LSHF SHETHED POWER CBLES 5
COMPRISON OF MIN PROPERTIES BETWEEN PVC ND XLPE INSULTION Insulation is made of plastics material; they are divided into two groups depending on how they react to heat. Thermoplastics can be repeatedly softened by heating and hardened by cooling. When you heat thermoplastics like PVC, the molecules do not chemically bond with each other. Instead, thermoplastic chains are held together by weak attractions between molecules. When heated, these chains slip off from each other and the material melts. On the other hand, in case of thermosetting plastics, the cross-links or chemical bonds between molecular chains prevent displacement at elevated temperature. Thus thermosetting plastics do not become soft or change their shape on heating. Thermosetting plastics harden permanently once it is moulded and cured. XLPE is polyethylene with their molecular chain cross-linked. The network structure of the molecular chains cannot deform and the excellent properties that polyethylene has at room temperature are retained at elevated temperature. The cross-linking of the molecules also has the effect of enhancing room temperature properties.

NOTE : NOTE : NOTE : The current-carrying capacity for a cable in the size range to, having more than loaded cores, is obtained by multiplying the current-carrying capacity of a -core, having the same insulation type, by the factor selected from this table. The current-carrying capacity for the -core cable is that for the installation condition to be used for the multicore cable. If, due to known operating conditions, a core is expected to carry not more than 0% of its current-carrying capacity in the multicore cable it may be ignored for the purpose of determining the number of cores in the cable. If, due to known operating conditions, a core is expected to carry not more than 0% of its rating after applying the rating factor for the total number of current-carrying cores, it may be ignored for the purpose of obtaining the rating factor for the number of loaded cores. For example, the current-carrying capacity of a cable having N loaded cores would normally be obtained by multiplying the currentcarrying capacity of a -core, having the same insulation type, by the factor selected from this table for N cores. That is I zlc = I tc x C gn where: I zlc is the current-carrying capacity of the multicore cable after applying the rating factor for the total number of current-carrying cores. I tc is the tabulated current-carrying capacity of a -core cable, having the same insulation type as the multi-core cable C gn is the rating factor from Table T for the total number of current-carrying cores 0 However, if M cores in the cable carry loads which are not greater than 0. x I tc x C gn, the current-carrying capacity can be obtained by using the rating factor corresponding to (N-M) cores. The not greater than 0. x I tc x C gn calculation should be applied before the adjacent muticore cable grouping factor, if applicable, from Table T. The 0% rule should not be further applied to any adjacent cable grouping factor calculations. I zlc should be greater than or equal to I n or I b as appropriate, divided by the relevant rating factor(s) C, that is I zlc I n or I b /C

Where horizontal clearances between adjacent cables exceed twice their overall diameter, no rating factor need be applied. The same factors are applied to: - group of two or three single-core cables; - multicore cables If a group consists of both two- and three-core cables, the total number of cables is taken as the number of circuits, and the corresponding factor is applied to the tables for two loaded conductors for the two-core cables, and to the Tables for three loaded conductors for the three-core cables. If a group consists of n single-core cables it may either be considered as n/ circuits of two loaded conductors or n/ circuits of three loaded conductors. The rating factors given have been averaged over the range of conductor sizes and types of installation included in Tables T to T8 and the overall accuracy of tabulated values is within 5%. For some installations and for other methods not provided for in the above tables, it may be appropriate to use factors calculated for specific cases, see for examples Tables T and T7 Where cables having differing conductor operating temperature are grouped together, the current rating is to be based upon the lowest operating temperature of any cable in the group. If, due to known operating conditions, a cable is expected to carry not more than 0% of its grouped rating, it may be ignored for the purpose of obtaining the rating factor for the rest of the group. For example, a group of N loaded cables would normally require a group rating factor of C g applied to the tabulated I t. However, if M cables in the group carry loads which are not greater than 0. C g I t amperes the other cables can be sized by using the group rating factor corresponding to (N-M) cables.
