3M Electrical Cable Termination Products

  • Medium Voltage Terminations

    3M offers you two options for choosing a medium voltage (5 kV–46 kV) electrical cable termination. The QT-III termination utilizes the latest technology with built-in Hi-K stress controlling mastic and environmental sealing mastic resulting in a much more user-friendly application. The QT-II termination offers some of the same advantages as the QTIII termination but without a few of the time-saving features that the QT-III termination possesses. All terminations meet or exceed IEEE 48 requirements.

  • High Voltage Terminations

    3M high voltage terminations (69 kV–145 kV) are designed to provide high reliability and save you time and money. They install quickly and easily, helping to reduce potential craft errors. They require no special tools, adhesives, torches, or other heat sources. Once installed, the cold shrink accessory creates a dynamic, compressive environmental seal and electrical interface without sealants or adhesives.
