3M™ Cold Shrink QT-III Termination Kit 7673-S Series for 69/72.5 kV
- 3M ID EEBGHAR000636
Details
Highlights
- A better compact design makes installations easier in restricted spaces
- Installation temperature range of -4 degrees F to 122 degrees F (-20 degrees C to 50 degrees C)
- 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)
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.
