KI – XL - 09 / XL – 10BK is a combination of KI-XL-09, a Silane Grafted PE compound and a masterbatch, KI-XL- 10 BK, which contains catalyst, carbon black, UV stabilizers and antioxidants. The KI-XL-10 BK masterbatch accelerates the moisture-induced crosslinking reaction and imparts track resistance, resistance to degradation by ultraviolet light stability to the final product. KI – XL - 09 / XL – 10BK is designed for use as a track resistant insulation for the outer layer of Spacer Aerial Cables and as insulation for Partial Insulated Cables. This compound is suitable as insulation for cables rated at voltages up to 33KV. Such system allows the compound to be extruded as a normal thermoplastic in a conventional PE (or even PVC) extrusion line, thus obviating the need of an expensive continuous vulcanizing (CV) extrusion line. The cross-linking step 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 and temperature. KI-XL09 & XL10 BK 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
