Blue Sky, Sunny Day – trackside cable identification underway on existing 33kV cables using a Lee Vaughan cable identifier and setting up of the Accles & Shelvoke spiking gun under a sanction for cable testing.

Cables Spiked – 33kV power cable is spiked to ensure worker safety by short circuiting the high voltage power and making the cable “dead”.

Cables Cut – cable jointing position is prepared and cables cut.

Cables Stripped – the cable sheath is cleaned using jointers cable wipes and stripped using appropriate cable jointing tools.

Cable Preparation Perfection – the copper screen wires are peeled back over the cable jacket and taped using PVC tape. Marker applied for semi-con screens.

Cables Stripped – 33kV semi-con screen removed.

More Cable Stripping – 33kV XLPE insulation removed using Alroc stripping tools.

Ready For Jointing – both 33kV cables are expertly prepared and ready to be jointed using 3M QS2000 Cold Shrink.

Cold Shrink Tubes Parked – 3M cable joint components slid onto the 33kV cables before cable can be jointed.

Conductors Jointed – Pfisterer Sicon bolted connectors installed to joint the 300sqmm stranded copper conductors without resort to crimping tools and die sets.

Cold Shrink Joint – once cables are cleaned and grease has been applied then the 3M cable splice body and tapes are installed. Grease is applied onto primary insulation, semi-conductive screen and connectors.

Taping Time – electrical and mastic tapes applied to both sides of the cable joint. Earth Continuity – copper screen sleeve or stocking is then positioned and constant force springs applied.

Almost Done – 3M Cold Shrink outer jacket is then applied and the cable joint is now complete. The cable joint body is shrink down by turning and pulling out the zip core in counter clockwise direction.
