Grades KI-XL-09 / XL-10 combination is suitable for High Voltage Power Cables (HT) applications, upto 35 KV KI-XL09 & XL10 meets requirements as applicable under following standards, when processed using sound extrusion practice and testing procedure; • IS 7098 Part 2/ IS 10810 • BS 5467, 5468, 6724, 7655 • IEC 60502 • NEMA WC 70 & NEMA WC 71 The Sioplas compound (KI-XL09 & XL10) to be extruded as a normal thermoplastic in a PE extrusion line for insulation and suitable semicon compounds in semicon extrusion lines with triple crosshead (three layers in common cross head) and longer water trough for graded cooling, thus obviating the need of an expensive continuous vulcanizing (CCV) extrusion line. The cross-linking of extruded core is subsequently carried out by immersion in hot water or exposure to steam. In both cases, time of curing is to be optimized as a function of thickness of insulation, concentration of catalyst MB and temperature of water bath or steam.
