3M 7622-T-110 (7000006101) QT-III Cold Shrink Termination Kit, 5/8/15 kV, 2 AWG - 400 kcmil, Shielded Cable, 3 Terminations/Kit, Indoor

The 3M™ 7622-T-110 (3M stocking number 7000006101) is a QT-III Cold Shrink silicone rubber indoor tubular termination kit for terminating 5, 8 and 15 kV solid dielectric shielded power cable. Each kit makes three single-phase terminations on tape shield, wire shield or UniShield® cable with polyethylene (PE), cross-linked polyethylene (XLPE) or EPR insulation. The one-piece, non-skirted silicone rubber termination uses High-K stress relief (stress control tube plus conformable stress controlling compound) with a built-in environmental top seal, and is qualified as an IEEE Std. 48 Class 1 termination rated 110 kV BIL.

Conductor Range by Voltage Class (compression lugs or connectors)

• 5 kV: 4/0 AWG – 400 kcmil
• 8 kV: 3/0 AWG – 300 kcmil
• 15 kV: 2 AWG – 2/0 AWG (35 – 70 mm²)

Final kit selection is determined by cable insulation diameter: primary insulation O.D. 0.64" – 1.08" (16,3 – 27,4 mm), jacket O.D. 0.97" – 1.48" (24,6 – 37,7 mm).

Key Features

• IEEE Std. 48 Class 1 termination for 5, 8 and 15 kV cable, 110 kV BIL.
• Cold shrink installation — slide over the prepared cable and unwind the core; no heat, no special tools, no force fit.
• High-K stress control distributes the electrical field uniformly, keeping insulator surface stress below 15 V/mil at rated voltage.
• Tracking-resistant, hydrophobic dark gray silicone rubber insulator in a compact, non-skirted tubular design for restricted spaces.
• Rated for cables with 105°C (221°F) maximum continuous operating temperature and 140°C (284°F) emergency overload.
• Each kit includes 3 terminations, 3 pre-formed ground braids, 3 constant force springs, 3 EMI copper foil shielding tape strips, 6 mastic strips, a CC-2 cable cleaning preparation kit and instructions (lugs not included).

Applications

• Indoor and weather-protected locations, including pad-mounted switchgear and transformer enclosures.
• Switchgear, transformer, motor lead and bus connections.
• Free-hanging or bracket-mounted, upright or inverted installations.
