3M 5640 Silicone Rubber Termination Kits

3M™ 5640 and 5650 Series Quick Term II Silicone Rubber Termination Kits are one-piece Cold Shrink™ terminations for Jacketed Concentric Neutral (JCN) power cable. They meet the requirements of IEEE standards 48-1990, for class I terminations. In addition they meet German standard VDE 0278 parts 5 & 100, British standard A-B-N-T-9314. Similar terminations using Quick Term II technology meet French EdF standards HN 33-E-01 and HN 41-E-01. The 3M Quick Term II consists of a high dielectric constant (high-K) stress control tube insulated with a molded silicone skirted insulator. There is a four skirt design rated 15 kV, a six skirt design rated 25/28 kV and eight skirt design rated 34.5 kV. Each insulator design incorporates an extended base feature which when combined with mastic ensures a seal at the cable jacket end where the cable neutral wires are brought out. Quick Term II terminations are provided in an expanded state, mounted on a removable inner supporting plastic core. As supplied in this pre-stretched condition the termination is ready for field installation. During installation the core is unwound, allowing termination to shrink and form a tight seal. Collectively, these termination kits cover cables with primary insulation OD from 0.637” to 2.30” (16.2-58.4 mm) and with cable jacket OD from 0.93”-2.75” (23.6-70.0 mm). These kits can be used to terminate Jacketed Concentric neutral (JCN) power cables from: 4 AWG to 2000 kcmil at 15 kV, 2 AWG at 1750 kcmil at 25 kV and 1 AWG to 1500 kcmil at 34.5 kV.Information provided by 3M
