Material Notes:

3M™ Cold Shrink QT-III Silicone Rubber Skirted Termination Kits, 7650-S-HSG and 7660-S-HSG Series, are designed for applications requiring a high-ampacity ground. Each kit contains one-piece, skirted, silicone rubber termination with high-ampacity ground assembly and is qualified as IEEE Standard 48 Class 1 for outdoor weather-exposed applications. The termination assemblies consist of a skirted insulator, high-dielectric constant (High-K) stress control tube, conformable High-K stress controlling compound and built-in environmental top sealing compound. The insulator is made of a dark gray silicone rubber with excellent tracking resistance and hydrophobic properties.Information provided by 3M
