3M Cold Shrink QT-III terminations offer easy installation and
reliable performance when terminating indoor and outdoor medium
voltage cable. The unique step-core design combined with the built
in Hi-K stress control and silicone sealing compounds means simpler
installation on all types of cable. The QT-III assures long-term
reliability through an improved silicone rubber body with enhanced
hydrophobic recovery. UV stability and track and erosion
resistance. Plus its Hi-K stress control design delivers excellent
BIL performance and lower surface stress resulting in a more
compact termination. Through superior engineering, 3M Cold Shrink
QT-III terminations deliver maximum performance.
3M Cold Shrink Silicone Rubber Termination Kit QT-III 7640-S,
7650-S and 7660-S series can be used on cables with a rate maximum
operating temperature of 105oC and an overload rating of
140oC. QT-III 7640-S, 7650-S and 7660-S Series
terminations meet all requirements of IEEE Standard 48-1996, "IEEE
Standard Test Procedures and Requirements for High Voltage
Alternating-Current Cable Terminations" and are designated Class 1
for outdoor weather-exposed locations. The current rating of
these terminations meets or exceeds the current rating of the
cables on which they are installed.
