3M Cold Shrink Terminations (QTIII) are shown terminating 12kV 3 core XLPE (polymeric insulated) cables onto copper busbar with double hole compression cable lugs – the Nexans LC (longitudinally corrugated copper) type cable without screen wires is effectively terminated “cold” i.e. without need for naked flames associated with conventional heat shrink type cable terminations.
3M medium voltage primary distribution cable terminations are extensively used in substations and cable vaults with confined spaces where the presence of potentially explosive atmospheres and flammable gas preclude “hot-working”.
“Skirted” cable terminations feature integral rain sheds suitable for indoor (substation switchgear and transformer) or outdoor (pole-top mounted) installation. The 3 phases are clearly labelled using cable tags (Red, Yellow Blue) attached with conventional cable ties.
The MV feeder replacement project required the removal of an existing 400sqmm PILC medium voltage cable and installation of new 500sqmm XLPE single core cable system – the previous MV system under the cable terminations for grounding is obsolete and out of service.
Note the NEMA pad bolted connection – there is a ball stud on it which is used for applying your working grounds.
Longitudinal Corrugated Tape Shielding – a flat copper tape is corrugated at right angles to its length and then formed into a cylinder around the medium voltage cable core or inner cable sheath/jacket. LCT shield design enables rapid stripping and termination by the cable jointer. 3M GSK Shield Grounding Accessory Kits convert concentric neutral (CN) or jacketed concentric neutral (JCN) QT-II or QT-III Cold Shrink termination kits for use on longitudinally corrugated (LC) and tape shielded power cables.
