3MTM Cold Shrink QT-III Termination Kit 7620-T & 7690-T Series help provide a high-performance and void-free seal for the tape shield, wire shield, and UniShield® power cables. The kits are estimated to meet or exceed the lifetime of the cable and feature a high dielectric constant material that helps control the electric field stress distribution. For indoor and outdoor weather-protected applications, they help minimize installation time as no torches or other heating sources are needed. Additionally, they are simple to install even in confined work areas and meet or exceed IEEE Standard 48, Class 1 requirements for 5, 8, 15, 25/28, and 35 kV terminations. The insulator is made with dark gray silicone rubber, helping enable advanced tracking resistance, hydrophobic properties, and UV resistance. 3MTM Cold Shrink QT-III Termination Kit 7620-T & 7690-T Series are engineered to meet varying voltage requirements ranging from 5 to 35 kV.
