Cable Abandonment Kit or Cable End Cap?

This video by 3M Electrical explains why you would choose a cable abandonment kit over a cable cap.

3M cold shrink cable abandonment kits (live cable end seals) are used to temporarily or permanently seal power, control and instrumentation cables – this includes the abandonment of redundant or decommissioned low voltage offshore, marine and shipwiring power, control and instrumentation cables in both safe and hazardous area workplace locations, such as Zone 1 or Zone 2 according to ATEX Directive.

Unlike cable end caps the cable abandonment kits include a copper earth braid system for the safe grounding off cables in the event of future planned or accidental energisation of the electrical cable circuit – 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 – this is demonstrated in the 3M Training video below.

3M Cold Shrink Tubing

This video by 3M Electrical shows how to apply 3M Cold Shrink Tubing safely.

3M Cold Shrink Tubing is a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core – the cold shrink tubes are supplied for field installation in a pre-stretched condition without requirement to use any activation or installation tools.

Cold shrink tubes are available in both EPDM rubber and silicone.

The 3M video shows how to install the tubing by unwinding the removable core allowing the tube to shrink and form a waterproof cable seal. Cold Shrink is quicker, easier and safer to install than heat shrink tubing alternatives.

Cold Shrink Cable Caps

This video by 3M Electrical shows how to apply 3M Cold Shrink End Caps safely.

3M Cold Shrink end cable caps environmentally seal and mechanically protect exposed low and high voltage cable ends using no specialist tools, mastics or tapes – manually applied the cable caps are safe and fast to install in the field for immediate protection of unsealed cable ends against water ingress.

The 3M video explains how a Cable Abandonment Kit can be used to safely abandon a cable either permanently or temporarily. The Cold Shrink kit ensures that if the cable is accidentally re-energised it remains safe.

Cembre RHU131-C

Thorne & Derrick International are Main UK Stockists and Suppliers of Cembre tools including crimping and cutting types for all constructions of LV MV HV cable including medium/high voltage 11kV/33kV power cables.

The following short article provides useful instructions about how to crimp aluminium conductor cables using Cembre model RHU131-C presshead – with built in safety valve the tool with by-pass the oil supply when maximum pressure has been reached.

The following excerpts are taken from the Operating Manual of Cembre RHU131-C hydraulic presshead crimping tool – however this information applies to the following tool model variants Cembre RHU131.

Cembre RHU131-C hydraulic crimping head is suitable for installing the same range of cable lugs, crimp connectors and terminals as Cembre HT 131-UC

For competitive prices, stock availability and technical advice about the Cembre RHU131-C tool please do not hesitate to contact us.

Crimping Aluminium Cables

Hydraulic Crimping Presshead Accessories

Pre-Rounding Conductor (For Sectoral Cables)

Ensure all aluminium conductors are thoroughly cleaned using approved and suitable cable cleaning wipes prior to crimping.

From the table select the Cembre adaptors and pre-rounding dies for the appropriate conductor size.

Insert the upper adaptor Cembre AU130- and lower adaptor AC130–P into the head as per below.

Insert the pre-rounding die (94) into the AC130–P adaptor.

Position the conductor into the pre-rounding die (95) and locate the pre-rounding die (95) in the adaptor AU130.

Ensure that the pre-rounding die is correctly located in the adaptor with its upper slot in line with the internal adaptor pins.

Operate the hydraulic foot pump until the dies are fully closed, such as Cembre PO7000.

Release the hydraulic pressure and remove the compacted round conductor.

Die Insertion

Connector Cable Crimping

Remove the pre-rounding dies and the adaptor AC130–P from the presshead.

From the table select the containing die and indentor recommended for the conductor size.

Insert the indentor into the ram (09).

Insert conductor into the connector.

Locate the connector into the containing Cembre die then locate the containing die in the adaptor.

Commence indent crimping from the barrel end for both splices and terminals following the sequence shown below:

• For every operation ensure the die is correctly located in the adaptor with its upper slots in line with the internal adaptor pins
• Each indenting operation is completed when indentor and die are fully closed; it is recommended to continue pumping until the maximum pressure valve is activated and a “click” is heard

Adaptor Fitting & Removal

• Insert the upper adaptor AU130 (98) into the U-fork head (14) until secured by the locators (15).To remove the adaptor from the U-fork head, push the adaptor from the locators and slide out
• To insert the adaptor AC130–P(91), press the die release pin (12).

Insert the adaptor into the seat of the ram (09), until secured by the retaining pin (11). To facilitate this operation, an advancement of 3÷4 mm (0.11 – 0.16 in.) of the ram (09) is suggested. To remove the adaptor, press the die release pin (12) and slide the adaptor from the ram (09).
