3M 7000031602 – Frequently Asked Questions
1) What cable size does the 3M 7693-S-4 cold shrink termination kit fit?
The 7693-S-4 QT-III kit is built around a cable insulation outer diameter of 0.72 in (18.288 mm), with a conductor size of 1 AWG. One kit terminates a single conductor, and the carton holds 3 terminations, enough for one three-phase run. Measure over the cable insulation, not the jacket, when you check the fit.
2) Can the 3M QT-III 7693-S-4 termination be used outdoors on a riser pole or pad?
Yes. It is a skirted outdoor termination with 4 skirts, and the silicone rubber insulation cuts leakage current in damp conditions. It works indoors as well, so a single kit covers both ends of a run that goes from a vault to an exterior pole.
3) Will the 3M 7693-S-4 kit work on wire shield or UniShield cable, or only tape shield?
The kit terminates tape shield, wire shield and UniShield power cable. The spec sheet lists tape shield as the primary shielding type, and the shield ground connection is what changes between them, so follow the 3M instruction sheet path that matches the cable you are cutting into.
4) What voltage class is the 3M QT-III 7693-S-4 rated for?
Medium voltage, rated 15 kV class with a 150 kV BIL and 100 percent insulation level. The product designation covers 5 to 25/28 kV service depending on cable construction and insulation level, so match your system voltage and the cable's insulation percentage before you order.
5) Does the 3M 7693-S-4 termination kit come with a lug?
No lug or stem connector is packed in the kit. You order the connector separately. The compatible lug for this kit is the QL2-A-2-250. Plan the lug into the same order so the crew is not stopped at the termination.
6) Do I need a torch or heat source to install the 3M 7693-S-4 termination?
No flame, no heat gun. This is cold shrink technology, so the tube is factory expanded on a removable core and collapses onto the cable when you pull the core out. That is the reason it is used in vaults, manholes and other spots where an open flame is not allowed, and it takes the guesswork out of getting an even shrink.
7) How much cable length do I need for a 3M QT-III cold shrink termination?
Allow for a maximum installed length of 12.25 in for the finished termination, measured from the end of the jacket up. Add working slack above that for the lug and the equipment landing point, and confirm your cabinet or pothead has the vertical room before you cut.
8) Does the 3M QT-III 7693-S-4 kit include a breakout boot or rejacketing?
Neither. There is no breakout boot and no insulation rejacketing component in this kit, because it is a single-conductor termination. If you are terminating a three-conductor cable that needs a crotch sealed at the breakout, you need a separate breakout kit in addition to three of these terminations.
9) How many terminations do I get in one 3M 7693-S-4 carton?
Three per kit, which is one three-phase set. For a job terminating both ends of a three-phase medium voltage feeder you need two kits. The manufacturer part number to order against is 7000031602.
10) How does the 3M QT-III control electrical stress at the shield cutback?
The termination uses a high dielectric-constant material to regulate the distribution of electric field stress at the shield cutback, which is where a medium voltage termination fails if it is not managed. The silicone rubber body then provides a void-free seal over the cable, so there are no air gaps to ionize.
11) Is the 3M 7693-S-4 termination kit made in the USA?
Yes, country of origin is the United States. That matters on public works and utility contracts carrying domestic sourcing requirements, so keep the documentation with the submittal package.
