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).
