3M 7000149321 – Frequently Asked Questions

1) Will the 3M 7642-S-2 cold shrink kit fit my cable insulation diameter?
The 7642-S-2 QT-III kit is sized for cable with an insulation outer diameter from 0.64 to 1.08 inches (0.64 in is 16.256 mm at the low end). Measure over the extruded insulation, not over the jacket or the neutrals. If your insulation OD falls outside that window the cold shrink tube will either not recover tight or won't slide over, so a different kit in the 7640-S series is the answer.
2) What cable type and voltage class is this 3M QT-III termination kit for?
It terminates single-conductor concentric neutral (CN) and jacketed concentric neutral (JCN) shielded power cable at 5 to 15 kV, 100 percent insulation level, with a 110 kV BIL. One termination per kit. It is a medium voltage product and is not intended for tape shield or wire shield cable constructions.
3) Does the 3M 7642-S-2 kit come with a lug or connector?
No lug or stem connector is packed in the kit. You order the compression lug or connector separately, sized to the conductor. The kit also has no breakout boot and no insulation rejacketing components, so if your job needs those they are separate items too.
4) Can this 3M cold shrink termination be used outdoors on a riser pole or pad?
Yes. The 7642-S-2 is an outdoor skirted termination, and the skirts give it the creepage distance for weather and contamination exposure. The silicone rubber insulation holds up to UV and damp conditions and keeps leakage currents down. Skirted terminations also work indoors, so it covers both environments.
5) How much cable length do I need to leave for a 3M QT-III 7642-S-2 termination?
Maximum installed length is 9.80 inches from the cut end of the jacket to the top of the termination. Plan your conductor training and clearance in the cabinet or on the pole around roughly ten inches of finished termination plus whatever lug height you add.
6) What conductor size does the 3M 7642-S-2 cold shrink kit cover?
It is listed for 1 AWG conductor. The controlling dimension for the cold shrink body is still the insulation OD, 0.64 to 1.08 inches, since insulation wall varies by cable construction. Check the insulation diameter on your actual cable before committing to this kit.
7) How many terminations do I get in one 3M 7000149321 kit?
One. Each kit terminates a single conductor, and there is one kit per case. A three-phase run of single-conductor CN or JCN cable therefore needs three kits per end, six if you are terminating both ends.
8) Where is the 3M QT-III 7642-S-2 termination kit made?
Made in the United States, which matters if you are buying against a Buy American or domestic-content requirement on a utility or government project. The manufacturer part number to quote is 7000149321.
