Live Cable Joint – Triple Concentric PILC Cable (Street Lighting LV)

• Application: Triple Concentric PILC Cable (Street Lighting LV)
• Type: Live Cable Joint
• Cable Jointer: David Schofield – HV/LV Cable Jointer

• by Chris Dodds T&D - estimated reading time 5 minutes  

Today, we debut the skills and expertise of David Schofield, HV/LV Jointer. In the following commentary, David explains the cable jointing process when live cable jointing on LV low voltage cables.

Firstly, use a metal hack knife which is an essential hand tool in any cable jointers tool set to remove the steel tape armour from the cable to be jointed.

Use cable cleaning wipes to clean the lead cover and fit a 2-ended continuity bond to bridge the lead. Remove the lead and papers then fit a constant force spring around the lead – a cut is then applied to the 2nd part of the continuity bond around the outer concentric strands (neutral).

This enables the Jointer to cut the neutral in the middle of the cable joint – once cut form them back into a conductor and apply tape and reconnect with a Sicame connector with the single phase neutral included and the earths from both sides of the lead cut.

Next tape up just from the cable crutch of the neutral with Scotch 88 tape and remove papers. Next phase cut in the centre of the cable, this should be a live phase from into a conductor and Scotch 88 tape around the live strands which are live both ways. Now the reconnect with 2nd Sicame straight barrel and apply insulation patch. Tape next layer of papers from crutch to crutch and remove a section of tape and papers from the centre of this core revealing the inner phase. Install Sicame clamp connectors onto this core and with the single phase service core included apply rubber shroud onto this then apply water blocks. Finally, bond armours down and over protect the cable joint with the shell.

132kV Termination Using Pfisterer IXOSIL EST SUB Self Supporting Cable Termination

• Application: 132kV Cable Termination – Pfisterer EST SUB Self Supporting Type
• Cable Type: Pfisterer EST SUB Self Supporting Cable Termination
• Cable Jointer: Andy O’Malley (IBEW 258 EHV Cable Jointer / Cable Splicer – Allteck)
• Featured Manufacturer: Pfisterer

Pfisterer EST SUB

Self Supporting Cable Termination

Pfisterer oil-free and gas-free cable terminations for high voltage cables are environmentally friendly and reduce installation times by the HV Jointer – the cable terminations are available for voltage levels ranging from 52kV to 170kV and conductor cross-sections up to 2500sqmm.

The self-supporting Pfisterer EST design replaces conventional oil-filled and gas-filled outdoor cable terminations both in overhead line towers and transformer stations – the cleverly designed head fitting allows for any thermal expansion in the conductor.

The mounting frame on overhead line towers is now no longer needed since the cable termination can be installed onto the HV cable on the ground and then lifted onto the tower – this leads to very short turn-off periods of the overhead lines.

Pfisterer IXOSIL EST SUB Advantages

• Oil- and gas-free
• Leak-proof
• Compensation of cantilever forces
• Enables installation on the ground, no mounting frames required
• Time savings of up to 50% during cable preparation due to new technology
• 100% electrically routine-tested termination
• Low weight cable termination

Pfisterer MV HV cable plugs and terminations are suitable for all voltage levels and applications where medium or high voltage power must be reliably distributed within the electricity supply industry.
