A Silane Grafted Crosslinkable Polyethylene Compound, Curable by exposure to moisture, for insulation of Power Cables and possessing excellent extrudability at output rate. PP 411 has been specially developed for cables upto 11KV. The special formulation and compounding techniques used ensure that the contamination level is kept within the required limits for this voltage grade. PP 411 has general Melt Flow Index range of 0.5-0.8, which provides firm stability during extrusion, especially for the thick insulation required for high voltage. Silane Grafted Crosslinkable Polyethylene For Medium Voltage Power Cable Insulation. |
