3M™ Cold Shrink QT-III Inverted Termination Kit 7620-S & 7690-S Series are designed to effectively manage electrical field stress distribution while providing a void-free seal on the tape shield, wire shield, and UniShield® power cables. These kits provide an integrated design that helps promote installation consistency and process streamlining in indoor, outdoor settings, and inverted applications. Engineered with robust construction, the product comprises a high dielectric constant material and silicone rubber insulation, offering excellent thermal stability and UV protection. It utilizes cold shrink technology for easy installation that eliminates the need for force-fitting, while the sealing compounds help to apply constant radial pressure to the cable. The kits comply with IEEE Standard 48, Class 1 requirements for 5, 8, 15, 25/28, and 35 kV terminations and will accommodate most cable supplier bend radius specifications. 3M™ Cold Shrink QT-III Inverted Termination Kit 7620-S & 7690-S Series are engineered to meet varying voltage requirements ranging from 5 to 35 kV. For comprehensive technical information about a specific product in this series, please consult a 3M expert.
