QTIII - Medium Voltage Cold Shrink Terminations

QT-III Cold Shrink terminations from 3M offer easy installation and reliable performance when terminating indoor and outdoor medium voltage cable.
Long-term reliability is assured through an improved silicone rubber body with enhanced hydrophobic recovery, UV stability and track and erosion resistance.
This, plus its Hi-K stress control design delivers excellent BIL performance resulting in a more compact termination.
3M Cold Shrink QT-III terminations deliver maximum performance through superior engineering.

The unique step-core design which incorporates Hi-K stress control and silicone sealing compounds means simpler installation on all types of cable.

The complete assembly is pre-stretched and loaded onto a removable core. The disposable core can be recycled. The kits are designed for terminating solid dielectric jacketed concentric neutral (JCN) and concentric neutral (CN) power cables rated 5 through 35 kV.
  • Conforms to IEEE Standard 48 Class 1 requirements for 5, 8, 15, 25/28 and 35 kV terminations
  • One-piece versatile design, allowing quick installation and accommodating a wide range of cable sizes
  • Cold Shrink delivery system allows easy installation: Simply place termination over prepared cable and unwind core to shrink into place (no force fit required)
  • Hi-K stress control: Specially formulated high-dielectric constant material minimizes surface stress by more uniformly distributing the electrical field over the entire surface of the insulator
  • Compact design provides for easier installation in restricted spaces
  • Silicone rubber insulators, EPDM stress control tubes, stress controlling compound and environmental sealing compound are compatible with common solid dielectric insulations, such as polyethylene (PE), cross-linked polyethylene (XLPE) and ethlylene propylene rubber (EPR).
