  • The cold shrink delivery system makes installation easy – just slide the termination sub-assembly over the prepared cable and unwind the core to shrink in place
  • Accommodates all cable lug designs including hexagonal or deep indent crimping technologies, plus a variety of mechanical sheer-off connecting technologies
  • For cables with a maximum temperature rating of 105 degrees C and an emergency overload rating of 140 degrees C
  • 7673-S Series terminations conform to IEEE 48 Class 1 requirements for 69kV, 350kV BIL outdoor applications and to IEC60840 for 72.5 kV, 325kB BIL outdoor applications
  • Available with either 8 skirts or 10 skirts for areas with higher contamination
  • A complete termination assembly that is pre-stretched and loaded on a support core
  • Hi-K stress control and high dielectric constant material minimize surface stress by distributing the electrical stress over the entire insulator surface
  • Silicone rubber material works with all common solid dielectric cables, such as cross-linked polyethylene (XLPE), ethylene propylene rubber (EPR) or polyethylene (PE)
  • Installation temperature range of -4 degrees F to 122 degrees F (-20 degrees C to 50 degrees C)

For 72.5 kV Class terminations, trust in 3M Cold Shrink QT-III Termination Kits 7673-S Series. Part of 3M’s Core Technology Platform, the 3M 7673-S Series kits lets you make safe, single-phase terminations on a variety of power cable – from tape shield, longitudinally corrugated (LC) and jacketed concentric neutral (JCN) cable, to tape-over-wire (TOW) and wire-over-tape (WOT) shielded cable.

For areas with higher contamination, the 3M 7673-S-10 Series termination kit provides additional skirts and water-blocking materials to give you a longer creepage path. The complete termination is made up of 4 sub-assemblies: the Silicone Rubber Skirted Stress Control Assembly, Hi-K Stress Control Adapter Assembly, Silicone Rubber Lug Seal Assembly and Silicone Rubber Ground Seal Assembly. Following installation, the support cores can be recycled. When the job requires a cold shrink delivery system, you need the 7673-S Series 3M Cold Shrink QT-III Termination Kit. Our cable accessory products are 100% factory-tested and backed by our strong reputation.

Kit Contents: Each kit contains sufficient quantities of the following materials as appropriate to make one single-phase termination (lug not included unless requested in advance).
