Visico™ ME4425/ Ambicat™ LE4462 is a silane crosslinkable black compound system designed for overhead track resistant energy cables. Visico ME4425 is a medium density polyethylene, copolymerized with vinyl silane. LE4462 is a crosslinking catalyst masterbatch specially designed to be used with Visico ME4425 to accelerate the moisture-induced reaction and impart track resistance. The system crosslinks quickly in sauna or in hot water. Cable insulation with a proper mixture of Visico ME4425 (90 parts) and LE4462 (10 parts) exhibits excellent thermo-oxidative stability. The system can be used with copper or aluminum although overhead cables, covered conductors, is primarily aluminum conductors due to the weight saving versus copper for overhead pole cables. The use of ME4425 and LE4462 is designed to provide good weathering performance. If a semiconductive inner layer is required, we recommend to use Borealis LE0542 together with Visico ME4425/LE4462.
