Cold Shrink Cable Abandonment

3M CSCAK

Low Voltage Polymeric Cables up to 3.3kV

3M Cold Shrink Cable Abandonment Kits (CSCAK) are suitable for XLPE (SWA steel wire armoured) and EPR (GSWB galvanised steel wire braided) insulated cables, including single and multicore cables with lead sheath, 600/1000v up to 3.3kV.

3M CSCAK cold shrink cable abandonment kits (live cable end seals) are used to temporarily or permanently seal power, control and instrumentation cables – especially the abandonment of redundant or decommissioned low voltage offshore, marine and shipwiring power, control and instrumentation cables.

The abandonment kits manufactured by 3M Electrical are cold-applied suitable for Zone 1 and Zone 2 hazardous area electrical installations according to the ATEX Directive without need for heat shrink procedures or “hot-working” with naked flames in potentially explosive environments.

Unlike cable end caps, the cable abandonment kits include copper earth braid system for the safe grounding off cables in the event of future planned or accidental energisation.

The cable sheath and cores should be covered and protected with copper earth braid and bonded using constant force springs to effectively short-circuit the cable system if energised. Copper binder wire and shielding braid is used to abandon and ground the individual cable cores.

Cold shrink cable caps are positioned and installed onto the cable end – the “live-memory” action of cold shrink effectively shrinks down to create a reliable watertight and durable environmental seal exerting a constant radial pressure.

An outer cold shrink tube is positioned over the cable end cap and into contact with the cable sheath.

Cable Compatibility for 3M CSCAK Abandonment Kits

3M CSCAK suits LV Cables XLPE EPR Insulated Cables, PVC or Low Smoke Zero Halogen (LSZH), Lead Sheath, Wire Armour (SWA) & Wire Braid (Galvanised & Phosphur Bronze), this includes onshore and offshore marine and shipwiring cables. Customised cable abandonment kit can be produced for certain applications including MI type Mineral Insulated cables.

See cable abandonment kits and products for high voltage cables including 6.6kV/11kV/33kV pot-end joints.
