| 3M™ Cold Shrink 5600 and 5680 Series QT-II Termination Kits contain one-piece silicone rubber terminations designed for concentric neutral (CN) cable. They meet the requirements of IEEE 48-1990 for Class I termination. In addition, they meet German standard VDA 0278 parts 5 & 100, British standard BS C-89, Spanish standard UNE 21-115-75 and Brazilian standard A-B-N-T-9314. Similar terminations using Cold Shrink technology meet French EdF standards HN 33-E-01. Data on foreign standards are available upon request. The 3M termination consists of a high dielectric constant (Hi-K) stress control tube insulated with a molded silicone skirted insulator. There is a four-skirt design rated 25/28 kV, and an eight-skirt design rated 35 kV. Cold Shrink QT-II terminations are provided in an expanded state, mounted on a removable inner supporting plastic core. As supplied in this prestretched condition the termination is ready for field installation. During installation the core is unwound, allowing the termination to shrink and form a tight seal. Collectively, these terminations kits accommodate cable primary insulation diameters from .632” to 2.75” (16-70 mm). These kits can be used to terminate the following concentric neutral (CN) power cables: #2 AWG to 1250 kcmil at 15 kV; #2 AWG to 1500 kcmil at 25 kV and #2 AWG to 2000 kcmil at 35 kV.Information provided by 3M |
