3M 7000006102 3M, Cold Shrink QT-III Termination Kit 7624-T-110, Tape/Wire/UniShield Shielding, 5-15 kV, 1 Kits/Case, Indoor

The 7624-T-110 QT-III kit is sized for 250 kcmil conductor with an insulation outer diameter of 0.83 in (21.082 mm). Sizing on cold shrink terminations is driven by the insulation OD over the primary insulation, not by the conductor size alone, so measure the cable's insulation OD after stripping the jacket and shield and confirm it lands at roughly that 0.83 in figure before you install. If your cable measures well outside that, you need a different range in the 7620-T series.

No. The 7624-T-110 is the indoor, non-skirted version. Non-skirted means there are no external sheds to extend creepage distance, which is what an outdoor termination needs to handle wetting and contamination. For outdoor switchgear, riser poles, or anything exposed, specify a skirted outdoor QT-III termination instead.

It seals to tape shield, wire shield, and UniShield power cables, so one kit covers the three common medium voltage shield constructions you are likely to find in a commercial or industrial feeder. The cataloged shielding type on the kit is tape shield. The high dielectric-constant stress control material handles the field concentration at the shield cutback, and the silicone rubber body gives a void-free seal over the shield.

Yes, lugs are not in the box. The kit does not include a lug or stem connector, and the matching compression lug is the 3M QL2-A-1/0-350, which covers 1/0 through 350 kcmil. Order lugs at the same time or the terminations cannot be landed.

One kit contains three terminations, one per phase, so a single kit terminates one end of a three-phase circuit built from three single-conductor cables. Each termination is one-piece and handles one conductor. If you are terminating both ends of the run, order two kits.

Allow at least 12 inches of length per termination, which is the maximum installed length of the 7624-T-110. Cold shrink means no torch and no heat gun, so you do not need clearance for a flame, but you do need enough straight cable and working space to slide the pre-expanded tube on and pull the core out.

Neither. This kit is the termination only: no breakout boot and no insulation rejacketing component. If your installation needs a three-phase breakout at the point where the triplexed cable separates, that is a separate item. Order it alongside the kit rather than assuming it is in the carton.

Cold shrink terminations like the QT-III go on with no flame, no torch, and no heat gun, which matters in an occupied building, a live substation room, or anywhere a hot work permit would slow the job down. The silicone rubber body stays elastic and keeps pressure on the cable as it heats and cools under load, so the seal does not depend on the installer's heat technique. The tradeoff is that sizing is tighter: you have to match the insulation OD range, here 0.83 in, rather than relying on a heat shrink tube's wider recovery range.

Yes, it is manufactured in the United States, which is what government, utility, and federally funded institutional buyers need to confirm for domestic sourcing requirements on a project.
